Which companies can use engineering plastics

The application of nylon in various industries.

Wardf Polymers (Shanghai) **** Engineering Plastics Application Research Department.

Polyamide PA6 66 (commonly known as nylon) belongs to the technical polymer family (engineering plastics). These resins are mainly used in technical applications with high physical and mechanical properties. In particular, polyamides have the following properties:

High rigidity and creep resistance

High impact resistance

High thermal stability

High abrasion resistance

High chemical resistance

Good electrical characteristics

Good processability good processing

Good aesthetic look good aesthetic look

Good fillability, colorability, impact modification, thermal stability, self-extinguishing, etc.

Due to the above-mentioned characteristics, nylon is widely used in automobiles, electrical equipment, mechanical parts, transportation equipment, textiles, papermaking machinery, etc. The disadvantage is that the water absorption is large, which affects the dimensional stability and electrical properties, and the fiber reinforcement can reduce the water absorption of the resin, so that it can work at high temperature and high humidity. Nylon has a very good affinity with glass fiber.

With the miniaturization of automobiles, the high performance of electrical and electronic equipment, and the weight reduction of machinery and equipment.

Definition of engineering plastics: can replace some metal materials; The continuous use temperature (cut) is greater than 100 °C.

As far as the current trend is concerned, many aspects such as electronic appliances and automobiles have begun to consider replacing metal materials with engineering materials, because they not only have better strength and stiffness, but also have a lighter specific gravity and stronger chemical resistance than metal materials.

It is an industrial plastic that is used as an industrial part or shell material, and it is a plastic with excellent strength, fiber deficit and impact resistance, heat resistance, hardness and aging resistance. <

Polycarbonate (PC), polyamide (nylon), polyacetal (POM), modified polyphenylene ether (denatured PPE), polyester (PETP, PBTP), polyphenylene sulfide (PPS), polyaryl ester, unsaturated polyester, phenolic plastic, epoxy plastic, etc. Engineering plastics are industrial plastics that are used as industrial parts or housing materials, and are plastics with excellent strength, impact resistance, heat resistance, hardness, and aging resistance.

General plastics: generally refer to commonly used plastics with large output, wide use, good moldability and low moldability. Such as polyvinyl chloride, polyethylene, polypropylene, polystyrene, etc.

Engineering plastics: generally refer to those with good physical and mechanical strength, and can still maintain good mechanical energy, electrical properties, chemical properties, wear resistance, heat resistance and dimensional stability at high and low temperatures.

Special engineering plastics: In addition to the characteristics of engineering plastics, their comprehensive properties are higher, and the long-term use temperature is more than 150 meters.

The so-called engineering plastics refer to the industrial plastics that are used as industrial parts or shell materials, and are plastics with excellent strength, impact resistance, heat resistance, hardness and aging resistanceEngineering plastics refer to the plastics that are used as structural materials in the project, and the common engineering plastics are polyamide, polytetrafluoroethylene, ABS plastics, polyoxymethylene, polycarbonate, etc. Ordinary plastics refer to synthetic resins with high molecular weight as the main components, and generally refer to plastics with large output, wide use, good moldability and low cost. There are five major varieties of general-purpose plastics, namely polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and acrylonitrile, butadiene styrene (ABS).
