What are the types of Jiangmen engineering plastics
Engineering plastics have the characteristics of high rigidity, small creep, high mechanical strength, good heat resistance and good electrical insulation, which make them suitable for long-term use in harsh chemical and physical environments and can replace metals as engineering structural materials. With the development of technology, the application of engineering plastics has been expanding, and has been extended to cars, home appliances, aviation, medical treatment, sports, electronics, construction and other fields.
1 polyamide of five engineering plastics
Polyamide (PA) is a kind of engineering plastic with excellent functions. It has excellent mechanical functions, excellent corrosion resistance, oil resistance, heat resistance, high modulus and other benefits. Strengthening and flame retardant modification can significantly improve its heat resistance, modulus standard stability and flame retardant. It is widely used in car, electronic and electrical, electric tools and other industries.
Application of PA plastics in the field of home appliances: mainly used for electrical parts of unattended electrical appliances.
Application of PA plastics in the field of cars: PA has good inductive function. After being reinforced by glass fiber, the strength, standard stability and other functions have been improved, and the price is relatively cheap. Therefore, it has become an ideal material for the peripheral parts of the engine. Intake manifold is the most typical application of modified PA in cars. In addition, the modified nylon is generally used as the preferred material for engine cover, engine decoration cover, cylinder head cover and other components. In addition to engine components, modified PA can also be used for oil filter, wiper, radiator grille, etc.
2 polycarbonate of five engineering plastics
Polycarbonate (PC) series includes toughening, strengthening, flame retardancy, etc. through modification, its flame retardancy and strength can be significantly improved, making the modified materials widely used in car parts, OA products, electronic and electrical products, etc.
Application of PC plastics in the field of home appliances: because of its high mechanical function and excellent appearance, the modified PC is professionally used in the field of home appliances. It is usually pc/abs alloy, with high resistance, stress cracking resistance, heat resistance, high weld line strength and other benefits.
Application of PC plastics in the field of cars: due to its high mechanical function and excellent appearance, modified PC is mainly used in car interior and exterior decoration, and the most widely used are pc/abs alloy and pc/pbt alloy. Pc/abs alloy is also used to manufacture car parts such as components around the instrument panel, anti freezing plate, door handle, negative flow plate, bracket, steering column sheath, decoration plate, air conditioning system accessories, etc. Pc/pet alloy can be used to manufacture car exhaust port and license plate cover. Pc/abs alloy can also be used to manufacture car exterior parts, such as car wheelhouse, reflector shell, tail lamp cover, etc. Pc/abs has excellent formability and can process large car components, such as car fenders.

3 polyoxymethylene of five engineering plastics
Polyoxymethylene (POM) is one of the five engineering plastics. It has the advantages of high hardness, wear resistance, creep resistance and chemical corrosion resistance. It is widely used in the fields of cars, electronic appliances and household appliances.
Application of POM plastics in the field of home appliances: such as the turbine and power wheel of washing machine, various parts, shells, sliding parts, support frames, etc. of microwave oven.
Application of POM plastics in the field of cars: the modified POM has low wear resistance coefficient and strong rigidity, and is very suitable for manufacturing car pumps, carburetor components, oil pipelines, power valves, Wanshang section bearings, motor gears, cranks, handles, instrument panels, car window elevator equipment, electric switches, safety belt buckles, etc. Manufacturing shaft sleeves, gears, sliding blocks and other wear-resistant parts is the strength of modified POM. These parts have little metal wear, reduce the amount of lubricating oil, and enhance the service life of the parts. Therefore, they can widely replace copper, zinc and other metals to produce bearings, gears, pull rods, etc. POM has been widely used in the car manufacturing industry because of its light components, low noise and simple forming devices.
4 polybutylene terephthalate, one of the five engineering plastics
Polybutylene terephthalate (PBT) is a kind of engineering material with excellent function. It has excellent resistance to fatigue, heat and weather, good electrical function and low water absorption. Strengthening and flame retardant modification can significantly improve its heat resistance, modulus, standard stability and flame retardant. It is widely used in car, home appliance and other industries.
Application of PBT plastics in household appliances: flame retardant PBT is mainly used in household appliances with flame retardant requirements.
Application of PBT plastics in the field of cars: PBT plastics are widely used in bumper, carburetor assembly, fender, spoiler, spark plug terminal board, fuel supply system parts, instrument panel, car igniter, accelerator and clutch pedal. PBT Alloy is also widely used in luxury cars. Pbt/pc alloy has good heat resistance, stress cracking resistance, excellent wear resistance, chemical corrosion resistance, high low-temperature impact strength, easy processing and finishing. It is mainly used in bumper, floor, panel and motorcycle guard of high-end cars.
5 polyphenylene oxide of five engineering plastics
Polyphenylene oxide (PPO) has excellent physical and mechanical functions, heat resistance and electrical insulation, low moisture absorption, high strength and good standard stability. It is widely used in water related fields such as kettle covers, valve cores, water pumps and impellers.
The application of PPO plastics in the field of home appliances: heat resistance and stress cracking resistance, mainly used in the lid of electric kettle.
Application of PPO plastics in the field of cars: the modified PPO mainly uses parts with high requirements for heat resistance, flame retardancy, electrical function, impact function, standard stability and mechanical strength in cars. For example, ppo/ps alloy is suitable for wet, loaded occasions with high requirements for electrical insulation and good standard stability. It is suitable for manufacturing car wheel housing, front lamp glass slot, tail lamp housing and other parts, as well as car electrical components such as connection box, fuse box, circuit breaker housing and so on. Ppo/pa alloy has excellent mechanical function, standard stability, oil resistance, electrical insulation and impact resistance. It can be used to manufacture car external parts, such as large baffle, cushion, rear baffle, etc.
