Second, the types of engineering plastics

The types of engineering plastics are polycarbonate, polyoxymethylene, polyamide, thermoplastic polyester and modified polyphenylene ether.

1 & gt； ? Polyamide: (PA, common name: nylon) has attracted people's attention because of its unique characteristics of low specific gravity, high tensile strength, wear resistance, good self-lubrication, excellent impact toughness, rigidity and flexibility. In addition, it has the advantages of simple processing, high efficiency and light specific gravity (only 1/7 of metal), and can be processed into various products to replace metal, which is widely used in automobiles and transportation. Typical products include pump impeller, fan blades, valve seats, bushings, bearings, all kinds of instrument panels, automobile electrical instruments, hot and cold air control valves and other parts. Each automobile consumes about 3.6~4 kilograms of nylon products. Polyamide has the largest consumption proportion in the automobile industry, followed by electronics and electricity.

2 & gt？ Polycarbonate: (PC) has strength similar to that of non-ferrous metals, and has both ductility and toughness. Its impact strength is extremely high, it will not be damaged by hammering, and it can withstand the explosion of TV screen. Polycarbonate has excellent transparency and can be colored in any way. Due to the above excellent performance, polycarbonate has been widely used in various safety lampshades, signal lights, transparent protective plates of gymnasiums and stadiums, daylighting glass, high-rise building glass, car rearview mirror, windshield, aircraft cockpit glass and motorcycle driving helmet. The biggest consumer markets are computers, office equipment, automobiles, replacement glass and plates, and CD and DVD discs are one of the most potential markets.

3 & gt？ Polyoxymethylene: Polyoxymethylene (pom) is an excellent engineering plastic, which has been widely used abroad. Super steel. " Pom has hardness, strength and rigidity similar to that of metal, and has good self-lubricity, good fatigue resistance and elasticity in a wide range of temperature and humidity. In addition, it also has good chemical resistance. At a lower cost than many other engineering plastics, pom is replacing some markets traditionally occupied by metals, such as replacing zinc, brass, aluminum and steel to manufacture many parts. Since its inception, pom has been widely used in electronic and electrical, machinery, instrumentation, daily light industry, automobiles, building materials, agriculture and other fields. In many new fields, such as medical technology and sports equipment, pom also shows a good growth trend.

4 & gt？ Poly (butylene terephthalate): (PBT) is a thermoplastic polyester. Compared with other thermoplastic engineering plastics, unreinforced PBT has better processability and electrical properties. The glass transition temperature of PBT is low, and the mold temperature is 50℃, so it can crystallize quickly, and the processing cycle is short. Poly (butylene terephthalate) (PBT) is widely used in electronic, electrical and automobile industries. Because of its high insulation and high temperature resistance, PBT can be used as flyback transformer of TV, distributor and ignition coil of automobile, shell and base of office equipment, various external parts of automobile, fan of air conditioner, base of electric furnace and shell parts of office equipment.

5 & gt？ Polyphenylene ether: chemical abbreviation is PPO. Thermoplastic resin synthesized by oxidative coupling polymerization of 2,6-disubstituted phenol is generally khaki powder. Polyphenylene ether synthesized from 2,6-dimethylphenol is commonly used and has excellent comprehensive properties. Its greatest feature is excellent dimensional stability and outstanding electrical insulation under long-term load, and its service temperature range is wide. Polyphenylene oxide has been used for a long time in the range of-127 ~ 12 1℃. It has excellent water resistance and steam resistance, and the product has high tensile strength, impact strength and creep resistance. In addition, it also has good wear resistance and electrical properties. It is mainly used to replace stainless steel to manufacture surgical medical instruments. In the electromechanical industry, it can be used to make fasteners and connectors such as gears, fan blades, pipes, valves, screws, etc., and it can also be used to make parts in the electronic and electrical industry, such as coil formers and printed circuit boards.

Third,? What are the engineering plastics?

1. Thermoplastics: The resin has a linear or branched macromolecular chain structure.

3. General plastic

Polyvinyl chloride, polystyrene, polyethylene, polypropylene, phenolic resin, amino resin.

4. Engineering plastics

Broad sense: all plastics that can be used as engineering materials, that is, structural materials.

Narrow sense: plastics with certain metal properties can withstand certain external forces, have good mechanical properties, electrical properties and dimensional stability, and can still maintain their excellent properties at high and low temperatures.

General engineering plastics: polyamide, polycarbonate, polyoxymethylene, acrylonitrile butadiene styrene, polyphenylene ether (PPO), polybutylene terephthalate (PBTP) and their modified products.

Special engineering plastics (high performance engineering plastics): high temperature resistant and structural materials. Polysulfone (PSU), polyimide (PI), polyphenylene sulfide (PPS), polyethersulfone (PES), polyarylate (PAR), polyamideimide (PAI), polyphenylene ester, polytetrafluoroethylene (PTFE), polyetherketone, ion exchange resin and heat-resistant epoxy resin.

5. Functional plastics (special plastics)

Plastics with special functions such as radiation resistance, superconductivity, magnetic permeability and light sensitivity. Fluoroplastics, silicone plastics

6. Crystalline plastics

Plastic whose molecules are arranged regularly and keep their shape. Polyethylene, polypropylene, polyamide

7.amorphous plastics

A plastic in which long-chain molecules are wound into a ball (for thermoplastics) or form a network (for thermosetting plastics) and its shape remains unchanged. PS、PC、ABS .

Engineering plastics are an upgrade of ordinary plastics. Due to the different molecular structures, there are some differences in chemical resistance, friction resistance and electrical properties. Moreover, due to the different molding methods, some methods are suitable for each plastic, and some methods are only suitable for one or several plastics.
