PLA PLA (polylactic acid) is also known as polylactic acid, the production process of polylactic acid is pollution-free, and the product can be biodegradable to achieve recycling in nature, so it is an ideal green polymer material, and one of the representatives of biodegradable plastics. The structure of PLA has important influence on its heat resistance, toughness, mechanical strength, degradability and biocompatibility. The influence on heat resistance is mainly discussed below. There is only one submethylene on the main chain of PLA molecule, the molecular chain has a spiral structure, and its activity is poor. As a result, the PLA after injection molding almost does not crystallize due to slow crystallization speed, so the heat resistance of the product is poor. During hot processing, the ester bond is partially broken to produce terminal carboxyl group, which plays an autocatalytic degradation effect on the thermal degradation of PLA. LGF reinforced PLA The rigidity of the fiber makes it play the role of skeleton support in the polymer matrix. When the polymer is heated, the movement of the chain segment is limited, thus improving the heat resistance of the material. At present, the fibers that can be used for enhancement modification of PLA include natural plant fiber (sisal, flax, linen, bamboo, coconut, wood fiber, etc.), natural animal fiber (silk, etc.), mineral fiber (basalt fiber, etc.), and chemical fiber (carbon fiber, glass fiber, etc.). Among these fibers, carbon fiber and glass fiber are widely used for their high strength and high modulus. Natural plant fiber has been widely studied because of its wide source, degradability and improved thermal and mechanical properties of composites. Modified natural fiber and modified inorganic fiber (glass fiber or carbon fiber) were mixed into the PLA matrix to prepare two kinds of fiber reinforced PLA composites. The test results show that the Vica softening temperature of the composites exceeds 140℃. Compared with Short fiber(SGF) Compared with the short fiber, it has more excellent performance in mechanical properties. It is more suitable for large products and structural parts. It has 1-3 times higher (toughness) than short fiber, and the tensile strength (strength and rigidity) is increased by 0.5-1 times.

PLA information PLA, also known as polylactide, refers to the polyester polymer obtained by polymerization of lactic acid as the main raw material, usually using renewable plant resources (such as corn, cassava, etc.) made of starch as raw material. It is a new type of renewable biodegradable material. PLA material characteristics The raw materials are renewable and relatively easy to obtain even if used as 3D printing materials, which can be used for large-scale production; The PLA has good thermal stability and solvent resistance. The processing temperature of PLA is between 170 ℃ and 230℃, and the finished product has good heat resistance. Good permeability and transparency luster, can be processed by extrusion, spinning, biaxial stretching, injection blow molding and other ways, tensile and bending modulus can be comparable to the traditional plastic resin; High biocompatibility. The monomer material of PLA, L-lactic acid, is an endogenous active substance in human body. Therefore, the finished product printed by 3D printing material PLA is non-toxic to human body and can be absorbed by human body. It has good degradability. Different from the degradation methods of other 3D printing materials, PLA is embedded in the soil and completely degraded by microorganisms in nature under specific conditions to generate carbon dioxide and water. The carbon dioxide generated directly enters the soil organic matter or is absorbed by plants instead of being discharged into the air, which is recognized as an environmentally friendly material. Application of PLA materials Due to the good mechanical and physical properties of PLA material, PLA material is widely used, including various food containers, packaged food, fast food lunch boxes, etc.  At the same time, with its advantages in compatibility and degradability, PLA can also play a large role in the medical field, which can be made into medical tissue skeleton material and medical carrier for human body. In addition to its excellent tensile strength and extensibility, PLA can be produced by various common processing methods, such as melt extrusion molding, injection molding, blow film molding, foam molding and vacuum molding. About us

Long carbon fiber Carbon fiber has many excellent properties, high axial strength and modulus, low density, high specific performance, no creep, super high temperature resistance in non-oxidizing environment, good fatigue resistance, specific heat and electrical conductivity between non-metal and metal, small coefficient of thermal expansion and anisotropy, good corrosion resistance, good X-ray transmission. Good electrical and thermal conductivity, good electromagnetic shielding, etc. Compared with traditional glass fiber, carbon fiber has more than 3 times of Young's modulus; it is about 2 times of Young's modulus compared with Kevlar fiber, which is insoluble and swollen in organic solvents, acids and alkalis, and has outstanding corrosion resistance. But is there a way to reduce the price of carbon fiber? That is to mix it with relatively cheap nylon material to form a composite material with good performance and meet the requirements. In that case, there is no doubt that carbon fiber nylon will definitely have a place in the composite material. Nylon itself is an engineering plastic with excellent performance, but moisture absorption, poor dimensional stability of products. Strength and hardness are also far from metal. In order to overcome these shortcomings, as early as before the 70s. People have used carbon fiber or other varieties of fibers for reinforcement to improve its performance. Carbon fiber reinforced nylon materials have developed rapidly in recent years, because nylon and carbon fiber are excellent performance in the field of engineering plastics materials, its compound material synthesis reflects the superiority of the two, such as strength and rigidity than unreinforced nylon is much higher, high temperature creep is small, thermal stability has improved significantly, good dimensional accuracy, wear resistance. Excellent damping, compared with glass fiber reinforced has better performance. Therefore, carbon fiber reinforced nylon (CF / PA) composites have developed rapidly in recent years. And for 3D printing using SLS technology is the most suitable technical means to achieve carbon fiber reinforced nylon.

Carbon Fiber Reinforced Plastic Carbon fiber reinforced plastic composite (CFRP) is a lightweight, strong material that can be used to make a wide range of products used in everyday life. It is a term used to describe fiber reinforced composites with carbon fiber as the main structural component. Note that the "P" in CFRP can also stand for "plastic" rather than "polymer." Typically, CFRP composites use thermosetting resins such as epoxy, polyester, or vinyl esters. Despite the use of thermoplastic resins in CFRP composites, "carbon fiber reinforced thermoplastic composites" often uses its own acronym, CFRTP composites. LFT-G focuses on LFT&LFRT. Long Glass Fiber Series (LGF) & Long Carbon Fiber Series. Compared with Short Carbon Fiber, Long Carbon Fiber has more excellent performance in mechanical properties. It is  more suitable for large products and structural parts. It has 1-3 times higher (toughness) than Short Carbon Fiber, and the tensile strength(strength and rigidity) is increased by 0.5-1 times. Properties of CFRP composites Composites reinforced with carbon fiber are different from other FRP composites that use traditional materials such as glass fiber or arylon fiber. Advantages of CFRP composites include: Light weight: Conventional fiberglass reinforced composites using continuous fiberglass and 70% fiberglass (glass weight/gross weight) typically have a density of 0.065 lb/cubic inch. A CFRP composite with the same 70% fiber weight might typically have a density of 0.055 lb/cubic inch. Increased strength: Carbon fiber composites not only weigh less, but CFRP composites are stronger and stiffer per unit weight. This is true when comparing carbon fiber composites to glass fibers, and even more so when comparing metals. For example, when comparing steel to CFRP composites, a good rule of thumb is that a carbon fiber structure of the same strength typically weighs 1/5 as steel. You can imagine why car companies are looking into using carbon fiber instead of steel. When comparing CFRP composites to aluminum (one of the lightest metals used), the standard assumption is that an aluminum structure of the same strength might weigh 1.5 times as much as a carbon fiber structure. Of course, there are many variables that can change this comparison. Grades and qualities of materials may vary, and for composites, the manufacturing process, fiber structure and quality need to be considered. Disadvantages of CFRP composites Cost: As amazing as the material is, there's a reason carbon fiber can't be used in every situation. Currently, the cost of CFRP composites is too high in many cases. Depending on current market conditions (supply and demand), the type of carbon fiber (aerospace grade versus commercial grade), and bundle size, carbon fiber prices can vary significantly. On a per-pound basis, carbon fiber can cost anywhere from five to 25 times more than fiberglass. The difference is even greater when comparing steel with CFRP composites. Electrical conductivity: This can be a plus or minus for carbon fiber composites, depending on the application. Carbon fiber is extremely conductive, while glass fiber is insulating. Many applications use fiberglass instead of carbon fiber or metal, strictly because of electrical conductivity. For example, in the utility industry, many products require the use of fiberglass. This is one of the reasons why the ladder uses fiberglass as the ladder rail. The chance of electric shock is much lower if the fiberglass ladder comes into contact with the power cord. The situation with CFRP ladders is different. Although the cost of CFRP composites remains high, new technological advances in manufacturing are continuing to provide more cost effective products. Application of PP-LCF Long Carbon Fiber as the reinforcement material of CFRP, its proportion is only 1/4 of iron, specific strength is 10 times that of iron, elastic modulus is 7 times that of iron, carbon fiber excellent physical properties are played in various fields from sports goods to aircraft.

Polyphenylene sulfide is a new functional engineering plastic.

What is Polyamide 66 materials? PA66, abbreviation of Polyamide 66, chemical name polyhexanediylhexanediamine, commonly known as nylon 66. It is a colorless transparent semi-crystalline thermoplastic polymer, widely used in automotive, electrical and electronic appliances, mechanical instruments and meters, industrial parts and other industries. However, due to the high water absorption, poor acid resistance, low impact strength in dry state and low temperature, and easy to deform after absorbing water, which affects the dimensional stability of the products, the scope of its application has been limited to a certain extent. In order to improve the above shortcomings, expand its field of application, and better meet the requirements for the use of performance, people use a variety of methods to modify PA66, in order to improve the impact, heat deformation, molding and processing performance and chemical corrosion resistance of PA66 plastic. As the specific strength and Young's modulus of glass fiber (GF) is 10-20 times larger than PA66, the coefficient of linear expansion is about 1/20 of PA66, the water absorption rate is close to zero, and there is good heat and chemical resistance, etc., so the glass fiber filling is the most commonly used means of enhancement and modification of PA66.                       Polyamide 66 fillin long glass fiber compounds Why do we use LFT plastics instead of metal? Many components that are currently manufactured in metal can be produced at lower cost and lower weight in high strength plastics. Compared to metals, plastics offer a number of significant advantages: • Faster production cycles • Lower investment in equipment and tooling • Elimination of finishing operations, such as machining or painting • No corrosion problems • Tighter tolerances • Easier assembly What is the difference between Long glass fiber and Stardard glass fiber? Long glass fiber (LGF) typically contain glass fibers with lengths of 10 to 12 mm, versus 0.7-mm fibers in standard glass-reinforced compounds. In the composite material made of fibers is sheared or pulled, the fibers are pulled out from the matrix, such a pulling process is conducive to the absorption of energy provided by the loading, the longer the fibers are within a certain length, the greater the absorption of energy, and the more significant its strength. And in the same volume amount, due to the longer the single fiber, the fewer the number of fiber roots, the less stress concentration generated at the fiber end, the more difficult the destruction of the material. From the results of practical application feedback, the various properties of long glass fiber reinforced thermoplastic composites are more excellent than Standard glass fiber. In addition, glass fiber reinforced composites in the friction process, the fiber body plays an important role in lubrication, long glass fiber can be much more sustainable, stable lubrication, so the coefficient of friction is lower, less wear, and the formation of the abrasive debris is finer. Because of these advantages, long glass-fiber reinforced thermoplastic composites perform better in real-world applications without fear of high frequencies and high loads. What is the advantages of Polyamide 66? Nylon 6/6 is composed of a molecular structure of higher order than Nylon 6, heightening Nylon 6’s positive characteristics: higher tensile strength and stiffness, better dimensional stability, and a higher melting point. Nylon 6/6 has a high lubricity and resistance to hydrocarbons; and exceptionally balanced strength, ductility, and heat resistance. As strong as it is independently, adding fillers, fibers, lubricants, and impact modifiers can increase Nylon 6/6’s strength times five and stiffness times ten.                       TDS of 30% long stand fiber glass reinforced Polyamide 6.6                  All TDS with 20%-60% fiber specification, please aks technologists What are the applications of Nylon 66 filling long stand fiber glass pellets? Frequently asked questions Q. Does long glass fiber and long carbon fiber injection have special requirements for injection molding machines and molds? A. There are certainly requirements. Especially from the product design structure, as well as the injection molding machine screw nozzle and mold structure injection molding process must consider the requirements of long fiber. Q. Using a long fiber reinforced thermoplastic material, will it  block the die hole due to the long length of the fiber or not? A. When using long glass fiber or long carbon fiber, it is necessary to evaluate whether the product is suitable for LFT-G. If the product is too small or the dispensing is not suitable for long fiber materials. The long fiber itself has requirements for mold nozzle. Q. How to choose the rei...
