Engineering plastics are thermoplastic plastics that can be used as structural materials. Engineering plastics have inductive functions, such as high rigidity, small creep, high mechanical strength, good heat resistance and good electrical insulation, which can be used in harsh chemical and physical environment for a long time.
Advantages of engineering plastics
Engineering plastics have the advantages of low density, light weight, high specific strength, good insulation, scale stability and corrosion resistance. They can be used in harsh physical and chemical environment, and have less environmental impact and durability.
Compared with general plastics, engineering plastics have better heat and cold resistance functions, and have excellent mechanical functions in a wide range of temperatures, so they are suitable for use as structural materials. Compared with metal materials, engineering plastics have the characteristics of convenient processing, high production efficiency, simplified production procedures and saving funds.
Application of engineering plastics in various occupational fields
Engineering plastics have mechanical functions, heat resistance, durability, corrosion resistance and so on. In many occasions, engineering plastics can replace metal materials, even better than metal materials. Engineering plastics have been widely used in more and more professional fields.
In car / traffic, engineering plastics are commonly used in exterior trim, interior trim, door, lampshade and engine parts.
In the field of electronic and electrical appliances, engineering plastics are used in air conditioners, televisions, washing machines, rice cookers, coffee machines and other small household appliances. In addition, it can also be used to make wire and cable coating, circuit board, insulating film materials and structural parts.
In terms of mechanical equipment, engineering plastics are used in bearings, gears, nuts, seals, fasteners, pipe joints and other mechanical parts and structural parts.
In terms of medical devices, engineering plastics can be used in surgical instruments, syringes, heart valves, bone correction and so on.
In the chemical industry, such as heat exchangers, chemical equipment fabrics and other chemical equipment and pipe and pipe fittings, valves, pumps and other chemical pipeline engineering plastics are involved.

Infrared penetrating PC material: it has the characteristics of processing function, initial transmission wavelength of 790nm and full transmission wavelength of 800nm. It is mainly used in signal transmission equipment, and the typical trademark is pc6783.
Laser laser engraving materials: materials are divided into injection molding grade, black carving white, non flame retardant, high gloss black, white carving black, halogen-free flame retardant. They are mainly used in the fields of electronics and electronics, cars and home appliances. Typical trademarks are abssm236, pcsm294, pa6sm264, pbtsm164, etc.
Antistatic materials: materials with high strength, high toughness, durable antistatic, dyeable, low cost, glass fiber reinforced, mainly used in household appliances, car interior, etc., typical trademarks are abs810-las, abs810-sas, pa66fg430-las, pa66fg430-sas.
Carbon fiber modified plastics: the material is mainly reinforced, which is a composite material with carbon fiber or carbon fiber fabric as reinforcement and PA / PC / ABS / PBT / PPO as matrix. It is mainly used in car manufacturing, electronic and electrical, household appliances, sports devices and other fields requiring high strength, high modulus, low specific gravity, antistatic, and conflict resistance. The typical trademarks of PCL are pa62133, pa62513, pa62922, PC / ABS 2123, PC / abs2513.
Wear resistant plastics: materials can supply a low coefficient of conflict to reduce wear rate. Wear resistant poly (ether ether ketone) is a kind of special engineering plastics with excellent inductive function. It is not only wear-resistant, but also has excellent heat-resistant, chemical corrosion-resistant, radiation-resistant, electrical and flame-retardant functions. It is widely used in the fields of cars, electronic appliances and mechanical chemical industry. Polyoxymethylene is wear-resistant, creep resistant, chemical corrosion resistant, and has high hardness. It is widely used in cars, electronic appliances and home appliances.
Conductive materials: conductive thermoplastic materials allow continuous release of static electricity, rather than rapid accumulation and discharge. The materials have the characteristics of high strength, high toughness, durable antistatic, dyeable, and low cost. They are used in household appliances and car interiors. Typical manufacturers of polycaprolone are labeled with abs810-las, abs810-sas, pa66fg430-las, pa66fg430-sas.
Easy coating materials: improve the surface polarity of polymer materials through special modification technology (PP material surface tension reaches 40 dyne), and then improve the interface affinity of materials. The material can reduce pre-treatment processes such as corona before spraying and printing for injection molding and rumored products.
