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. Automotive parts PA66's low specific gravity, high rigidity, strong toughness, heat resistance and gasoline resistance make it widely used in automotive modules, automotive structural parts, automotive interior and exterior parts, automotive transmission system and chassis shield, automotive fuel system, automotive ignition system, etc. The products involve automotive cable channel modules, structural parts of front-end components of automotive sunroof system, automotive rearview mirror bracket, automotive radiator, headlight support frame, door module, seat structural parts, seat shell and backrest, dashboard skeleton, air cooler fan, etc. Electrical and electronics PA66's good insulation, flame retardancy and corrosion resistance make it suitable for making various connectors, switches, sockets, terminal blocks, wire coverings, wire ties, insulating spacers, circuit breaker housings, transformer bobbins, retaining clips and motor parts after glass fiber reinforcement. Mechanical and engineering parts PA66's good rigidity, toughness, self-lubricating properties, heat and abrasion resistance make it suitable for manufacturing various nuts, screws, cable ties, worm gears, rotating wheels, gears, pump impellers, pulley sleeves, bushings, solenoid distribution valve seats, power tool housings, pipes, luggage racks, fan housings, appliance housings, door and window frames, cable drag chains and large machine tool baffles.

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.
