Nylon 66 is a kind of high-grade thermoplastic resin, which is an excellent polymer material for manufacturing chemical fibers and engineering plastics.

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...

Material Introduction In 1935, Wallace Carothers, a scientific researcher at DuPont, and his team successfully synthesized PA66 by condensation of adipic acid and adipic diamine for the first time, and DuPont completed the commercial production of PA66 fiber in 1939. Starting in the 1950s, PA, including PA6 and PA66, was developed for the production of injection molded products to replace metal to meet the requirements of light weight and cost reduction of industrial products. At present, PA66 is the most used PA species other than PA6. PA66 Scientific name: Polyhexanediamide Abbreviation: PA66 Common name: Nylon 66  PA66 has many similarities with PA6. PA66 is also a transparent to milky white granule that can take on almost any color with the addition of a colorant (masterbatch) specific for polymers. Material properties Similar to the basic properties of PA6, PA66 also has low specific gravity, high tensile strength, wear resistance, good self-lubrication, and excellent impact toughness. In addition, because the number of hydrogen bonds in PA66 is more than in PA6, the intermolecular force of PA66 is stronger than the intermolecular force of PA6, which makes the internal structure of PA66 more compact than PA6, with better thermal properties, higher rigidity and toughness, better dimensional stability, lower water absorption, and more wear resistance. However, PA66 has a higher market price than PA6 and is not as easy to process and mold as PA6. Like PA6, PA66 can also add a certain percentage of glass fiber, carbon fiber, etc. to improve the performance and meet the application needs of different products. The following table is a PA66-LCF30 performance table produced by Xiamen LFT composite plastic company. Materials Application PA66 has higher hardness, mechanical strength, toughness, self-lubrication, friction resistance, heat resistance after the addition of carbon fiber, and is widely used in automotive parts, electrical and electronic, as well as mechanical and engineering parts and other fields.

Polyamide 66 Nylon is the common name for polyamide (PA), a generic term for thermoplastic resins containing repeating amide groups on the main chain of the molecule, including aliphatic polyamides, aliphatic-aromatic polyamides and aromatic polyamides. As one of the top five engineering plastics, nylon has an extremely wide range of industrial applications, mainly in automotive parts, mechanical parts, electronics and appliances, cosmetics, adhesives and packaging materials. Among them, the largest production and most widely used are aliphatic polyamides, mainly nylon 66 and nylon 6. Nylon 66 (PA66) is made by condensation of adipic acid and hexanediamine, which is a class of polyamide. Advantages: high strength, corrosion resistance, good wear resistance characteristics, and has self-lubricating, flame retardant, non-toxic environmental protection and other excellent performance. Disadvantages: poor heat resistance and acid resistance, low impact strength in dry state and low temperature, high water absorption affects the dimensional stability and electrical properties of products. Polyamide 66 filling long carbon fiber High-performance fibers are chemical fibers with high load-bearing capacity and high durability because they have a special physical or chemical structure embodied with some excellent characteristics that traditional fibers do not have, such as high temperature resistance, corrosion resistance, flame retardancy and other properties. Carbon fiber is an inorganic polymer material with carbon content higher than 90% obtained from organic fibers through carbonization and graphitization. Advantages: light weight, high strength, high modulus, high temperature resistance, wear resistance, corrosion resistance, fatigue resistance, electrical conductivity, thermal conductivity, etc. Disadvantages: high cost, relatively difficult to infiltrate, poor transparency, etc. Carbon fiber composite materials are very useful structural materials, which are not only light, high temperature resistant, but also have high tensile strength and elastic modulus, and are indispensable materials for the manufacture of spacecraft, rockets, missiles, high-speed aircraft and large passenger aircraft. In transportation, chemical industry, metallurgy, construction and other industrial sectors, as well as sports equipment and other aspects have a wide range of applications. The density of PA66/CF composites tends to increase slightly as the content of CF increases. This is due to the fact that the density of CF is larger compared to that of PA66. The fracture surface of PA66 is smoother, while the fracture surface of PA66/CF sample is extremely rough and CF is pulled out, which indicates that the CF in the system plays a good role in bearing the load when the composite sample is subjected to external force, and this fracture is a ductile fracture, therefore, PA66/CF composite is a ductile material. With the increase of CF content, the tensile strength of PA66/CF composites increased significantly. The flexural strength and flexural modulus of PA66/CF composites are increased substantially with the increase of CF content.
