PA66 Nylon (PA) has a series of excellent properties, such as high mechanical strength, chemical resistance, oil resistance, wear resistance, self-lubrication, easy processing and forming, and has become one of the thermoplastic engineering plastics widely used at home and abroad. But in the practical application, the performance requirements of nylon are different under different conditions or environment. For example, electric drill and motor shell, pump impeller, bearing, diesel engine and air conditioning fan and other parts require nylon material to have high strength, high rigidity and high dimensional stability; Because of the poor toughness of nylon at low temperature, it is necessary to toughen it. In some outdoor applications, nylon materials must be weather-resistant modification in long-term outdoor environment. PA66-LCF Long carbon fiber reinforced nylon has excellent damping properties in 3D printing and has better performance than glass fiber reinforced nylon. In the design of tools for industrial applications, traditional techniques have used aluminum or alternative metal alloys because metal components perform better and meet the requirements of the tool. In many cases, thermoplastics can meet the strength requirements of such tools, but not the rigidity requirements for performing test tasks. Carbon fiber reinforced nylon is an ideal substitute for metal. Due to the combination of the light weight of nylon and the mechanical strength and thermal properties of carbon fiber, the strength and stiffness of carbon fiber composite nylon material is significantly improved, and its mechanical strength even exceeds that of 3D-printed PEEK and PEKK. In the automobile industry, from internal and external components such as vehicle anchors and instruments to engine housing, metal parts can be replaced. As we all know, automotive carbon fiber is widely used in automobile manufacturing due to its strong thermal and mechanical properties. As a substitute for metal parts, carbon fiber reinforced nylon has a wide range of application prospects in the automobile industry, which can realize the possibility of weight reduction and design optimization, as well as environmental protection and economic advantages.

Long Carbon Fiber In recent years, due to the growing demand for lightweight in various industries around the world (automotive, aerospace, military, building and civil engineering, etc.), and the increasingly strict requirements for the use of environmentally friendly and sustainable materials, the use of fiber reinforced thermoplastic composites in various industries has been increasing. Especially for carbon fiber reinforced composites, there is still a high recycling value after the products are discarded after completing their life cycle, and through effective recycling technology and methods, the cost of carbon fiber reinforced composites can be significantly reduced. The recovery method of fiber reinforced thermoplastic composites is closely related to the shape and forming method of fiber reinforced in resin. Take carbon fiber reinforced thermoplastic composites as an example. The reinforced forms of carbon fiber mainly include short fiber reinforced, long fiber reinforced and continuous fiber reinforced, and the main preparation method is melt forming. For thermoplastic resins with high melting point, such as polyetherimide (PEI) and polyetherether ketone (PEEK), solvent forming can be adopted. Due to the linear molecular structure of thermoplastic resin, it is easy to transform from solid state to liquid state at high temperature. Therefore, thermoplastic composite materials can be recycled by remelting and reshaping method, which is more recyclable than thermosetting resin matrix composite materials. PP-LCF datasheet Application Our materails all can be recycled At present, more and more companies are developing recycling methods for fiber reinforced thermoplastic composites. For example, the 2014 Chevrolet Corvette uses composite materials containing recycled carbon fiber in 21 body panel components, including doors, boot LIDS, side coops and fenders. Ford Motor Company has used recycled long carbon fiber and polypropylene (LCF/PP) composites to replace the original ASA engineering plastic as the rigid part of the A-pillar bracket in its 2018 Explorer sport utility SUV.

PLA-LCF Polylactic acid or PLA is a bio-based polymer made using lactic acid from the sugar fermentation process. It was originally intended as a more environmentally friendly alternative to crude oil-based polymers and is technically biodegradable (albeit under industrial compost conditions). In addition to being the most widely used polymer in the desktop 3D printing space, PLA also has a variety of applications in packaging, disposable cups and more. Although it is very cost effective, easy to process and easy to 3D print, pure PLA has poor thermal and mechanical stability and is therefore not suitable for any high performance applications. One way to improve material properties is to use additives such as carbon fiber reinforced materials, as carbon fiber composites can provide an excellent mix of mechanical properties and heat resistance. Long carbon fiber reinforced PLA is an outstanding material that is strong, lightweight, has excellent layer bonding and low warpage. It has excellent layer adhesion and low warpage. Long carbon fiber PLA is stronger than other 3D-printed materials. Long carbon fiber filaments are not as strong as other 3D materials, but tougher. The increased rigidity of carbon fiber means increased structural support but reduced overall flexibility. It is slightly more brittle than regular PLA. When printed, the material is a dark glossy color that shimmers slightly under direct light. characteristic The fracture strain is moderate (8-10%), so the silk is not brittle, but strong toughness Very high melt strength and viscosity Good dimensional accuracy and stability Easy to handle on many platforms High attractive matte black surface Excellent impact resistance and lightness Application of long carbon fiber filliing PLA material Long carbon fiber filling PLA is an ideal material for frames, braces, shells, propellers, tools, instruments, etc. Virtually no bending will occur.

ABS-LGF Long glass fiber reinforced ABS can improve the thermal deformation temperature and mechanical properties of ABS, and reduce the shrinkage rate and linear expansion coefficient of ABS. It is used to manufacture products with high dimensional precision. Fiber reinforced ABS general glass fiber content is 20% to 60%. The addition of 20% to 30% glass fiber is the most common. Generally speaking, the higher the long glass fiber content, the better the tensile strength, bending strength, elastic modulus and rigidity of the material, and the thermal deformation temperature also has a significant increase. However, if the long glass fiber is added too much, it will make the tensile strength, bending strength, elastic modulus, rigidity and other properties of the material decline.

HDPE introduce High density polyethylene (HDPE) is a white powder or granular product. Non-toxic, tasteless, crystallinity is 80% ~ 90%, softening point is 125 ~ 135℃, the use of temperature can reach 100℃; The hardness, tensile strength and creep property are better than low density polyethylene. Good wear resistance, electrical insulation, toughness and cold resistance; Good chemical stability, at room temperature, insoluble in any organic solvent, acid, alkali and all kinds of salt corrosion resistance; Thin film to water vapor and air permeability is small, low water absorption; Poor aging resistance, environmental stress cracking resistance is not as good as low density polyethylene, especially thermal oxidation will reduce its performance, so the resin must be added in antioxidants and ultraviolet absorbent to improve this deficiency. High density polyethylene film under the condition of stress thermal deformation temperature is low, should pay attention to the application. Long Glass Fiber filling High density polyethylene (HDPE)/ glass fiber (LGF) composites were prepared by twin-screw extrusion mechanism, and the mechanical properties and non-isothermal crystallization behavior of HDPE/LGF composites were studied. The results show that the impact strength of the composite can be improved by MAH-g-POE, and the interface bond between the glass fiber and HDPE is good. The Avrami index (n) of the composite does not change with the cooling rate. The effects of HDPE on the flow properties of PP and its mechanical properties, and the effects of the flow properties of PP/HDPE blends on the mechanical properties of LGF/PP/HDPE composites were studied. The results show that HDPE can not only improve the impact performance of PP, but also improve the liquidity of PP. The mechanical properties of LGF/PP/HDPE composites, such as tensile strength and bending strength, are mainly affected by the flow properties of the matrix, but have little effect on the mechanical properties of the matrix itself.

PA66 filling LGF Nylon (PA) has a series of excellent properties, such as high mechanical strength, chemical resistance, oil resistance, wear resistance, self-lubrication, easy processing and forming, and has become one of the thermoplastic engineering plastics widely used at home and abroad. But in the practical application, the performance requirements of nylon are different under different conditions or environment. For example, electric drill and motor shell, pump impeller, bearing, diesel engine and air conditioning fan and other parts require nylon material to have high strength, high rigidity and high dimensional stability; Because of the poor toughness of nylon at low temperature, it is necessary to toughen it. In some outdoor applications, nylon materials must be weather-resistant modification in long-term outdoor environment. The reinforced materials used for nylon are mainly glass fiber, carbon fiber, whiskers and other fibrous materials, and the glass fiber reinforced is the most widely used. The glass fiber reinforcement can obviously improve the rigidity strength and hardness of the material, and the dimensional stability and heat resistance of the material are obviously improved. Because nylon itself is not strong enough, by adding 10 to 30 percent of the fiber, to increase its strength. In particular, 30% strength is considered the most appropriate ratio. Also added to 40-50%, according to the specific requirements of different products, coupled with the appropriate formula, can be successful. Production technology of glass fiber reinforced nylon Long fiber method, that is, nylon and other components are premixed and added to the hopper, and the glass fiber from the glass fiber entrance through the screw rotation into the screw, and then mixed with nylon resin. Factors affecting the properties of glass fiber reinforced nylon Firstly, the interface bond between glass fiber and nylon resin has the most important effect on glass fiber reinforced nylon. If the combination between the two is not good, the reinforcement effect will be greatly reduced. At this time, the surface treatment of glass fiber is particularly important. Today, fiberglass manufacturers have been able to produce fiberglass models for different materials with different surface treatments for use by modified plastics manufacturers, as long as the right choice. Second, the length of glass fiber in nylon material is another major factor affecting its properties. In general, long glass fibers are superior to short glass fibers in terms of tensile strength, bending strength and modulus, and notched impact strength. At the same time, the dispersion of glass fiber in the material can not be ignored. The dispersion of glass fiber mainly depends on the appropriate shearing action of twin-screw and the kneading action of material, which involves the combination and speed of screw. The selection of screw speed is related to the content of additives such as glass fiber in the formula. For flame-retardant reinforced nylon, low speed is appropriate because the flame retardant has been decomposed by heat. In addition, processing temperature, glass fiber diameter, glass fiber type will also affect the final performance of the material, so it will not be repeated here. Glass fiber enhances the fluidity of nylon The fluidity of glass fiber reinforced nylon is poor, and problems such as high injection pressure, high injection temperature, dissatisfaction with injection molding and poor surface quality are easy to occur in the process of injection molding, which seriously affect the appearance of products and lead to a high defect rate of products. Especially in the production process of injection molding products, and can not directly add lubricant to solve the problem, can only be improved on the raw material, generally speaking, this needs to be added in the modified formula lubrication componentS. Resistance of glass fiber reinforced nylon to high temperature heat and oxygen aging In some applications such as bearings and diesel fans, glass fiber reinforced nylon often faces the problem of long time high temperature thermal and oxygen aging. Although the reinforced modification of nylon with glass fiber can moderately improve the heat resistance of nylon, it can not solve the problem well. Better results can be achieved by adding appropriate anti-thermal oxygen aging additives to the glass fiber reinforced nylon composite material, as shown in the figure above. Glass fiber enhances the weather resistance of nylon Nylon under the influence of sunlight, temperature change, wind and rain and other external conditions, there will be a series of aging phenomena such as fading, discoloration, cracking, powder and strength reduction, among which UV is the key factor to promote aging. Weather resistant nylon is currently mainly black products, that is, by adding carbon black and other ultraviolet absorption additives in nylon to solve its weather re...

What is PA6 plastic? polyamide (PA), usually called Nylon, is a hetero-chain polymer containing amide group (-NHCo -) in the main chain. It can be divided into aliphatic group and aromatic group. It is the earliest developed and the most used thermoplastic engineering material. Polyamide main chain contains many repeated amide group, used as a plastic called nylon, used as a synthetic fiber called nylon. A variety of different polyamides can be prepared according to the number of carbon atoms contained in binary amines and dibasic acids or amino acids. At present, there are dozens of polyamides, among which polyamide-6, polyamide-66 and polyamide-610 are the most widely used. Polyamide-6 is an aliphatic polyamide, with light weight, strong strength, wear resistance, weak acid and alkali resistance and some organic solvents, easy molding and processing and other excellent properties, widely used in fiber, engineering plastics and thin films and other fields, but PA6 molecular chain segment contains strong polarity amide groups, easy to form hydrogen bonds with water molecules, The product has the disadvantages of large water absorption, poor dimensional stability, low impact strength in dry state and low temperature, strong acid and alkali resistance. Advantages of nylon 6: High mechanical strength, good toughness, high tensile and compressive strength. Outstanding fatigue resistance, the parts after repeated bending can still maintain the original mechanical strength. High softening point, heat resistant. Smooth surface, small friction coefficient, wear-resistant. Corrosion resistance, very resistant to alkali and most salts, also resistant to weak acids, oil, gasoline, aromatic compounds and general solvents, aromatic compounds are inert, but not resistant to strong acids and oxidants. It can resist the corrosion of gasoline, oil, fat, alcohol, alkaline and so on, and has good anti-aging ability. It is self-extinguishing, non-toxic, odorless, good weather resistance, inert to biological erosion, and has good antibacterial and mildew resistance. Has excellent electrical performance, good electrical insulation, nylon volume resistance is high, high breakdown voltage resistance, in dry environment, can work frequency insulation material, even in high humidity environment still has good electrical insulation. Light weight, easy dyeing, easy forming, because of low melting viscosity, can flow quickly. Disadvantages of Nylon 6: Easy to absorb water, water absorption, saturated water can reach more than 3%. Poor light resistance, in the long-term high temperature environment will oxidize with oxygen in the air, the color turns brown at the beginning, and the subsequent surface is broken and cracked. Injection molding technology requirements more strict, the existence of trace moisture will cause great damage to the quality of molding; The dimensional stability of the product is difficult to control because of thermal expansion. The existence of sharp Angle in the product will lead to stress concentration and reduce the mechanical strength; If the wall thickness is not uniform, it will lead to the distortion and deformation of the parts. High precision of equipment is required in post-processing. Will absorb water, alcohol and swelling, not resistant to strong acid and oxidant, can not be used as acid-resistant materials. Why filling Long Glass Fiber? PA6 has excellent properties such as light weight, strong strength, abrasion resistance, weak acid and alkali resistance and some organic solvents, and easy molding and processing. It is widely used in the fields of fibers, engineering plastics and films. However, the molecular chain segment of PA6 contains highly polar amide groups, which are easy to form hydrogen bonds with water molecules. The product has the disadvantages of large water absorption, poor dimensional stability, low impact strength in dry state and low temperature, strong acid and alkali resistance. With the development of science and technology and the improvement of life quality, the defects in some properties of traditional PA6 materials have limited its development in some fields. In order to improve the performance of PA6 and expand its application field, PA6 should be modified. Filling enhancement modification is a common method for physical modification of PA6. It refers to the modification of PA6 by adding fillers such as glass fiber and carbon fiber into the matrix to significantly improve the mechanical properties, flame retardant properties, thermal conductivity and dimensional stability of the material. What is application of PA6-LGF? Modified section of 30% long glass fiber reinforced PA6 is the ideal material for processing power tool shell, power tool parts, engineering machinery parts and automobile parts. Its mechanical properties, dimensional stability, heat resistance and aging resistance have been significantly improved. The fatigue resistance strength is 2.5 times that of unenha...
