What Are The Classifications Of Plastics?

As a 3 Inch Plastic Stopper Wholesaler, let's talk about the classification of plastics.

a) according to the heat behavior

Thermoplastic

Common varieties: polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyamide, acrylonitrile-butadiene-styrene, PE, PP, PS, PVC, PA, ABS, polymethyl methacrylate, poly Tetrafluoroethylene, polyoxymethylene, polycarbonate, polyfluorene PMMA, PTFE, POM, PC, PSF. Such as PE Plastic Tube Core.

2. Thermoset plastic

Common varieties: phenolic plastics, epoxy plastics, unsaturated polyesters, PF EP UP silicone plastics.

b) According to the solid polymer macromolecular configuration

Crystalline plastic

PE, PP, PA, POM, formaldehyde

2. Unshaped

PS, PVC, PMMA, PC

                                                                                           
c) According to the scope of application

1. General-purpose plastics: large output, wide application, low price, and general performance. Production accounts for more than half of the total. Including 6 major varieties: polyethylene, polypropylene, polyvinyl chloride, polystyrene, phenolic, amino plastic, PE, PP, PVC, PS

It has high strength, good wear resistance, corrosion resistance, self-lubricity, and dimensional stability, that is, it has certain metal properties and can replace metal as some mechanical components.

Commonly used: polyamide, polyoxymethylene, polycarbonate, ABS, polyfluorene, polyphenylene ether, PA, POM, PC, ABS Plastic Core, PSF, PPO, PTFE

2. Special plastics: Plastics with certain special properties.

High heat resistance or high electrical insulation and corrosion resistance.

Such as: fluoroplastic: polytetrafluoroethylene. Anti-friction self-lubricating parts, various non-lubricated piston rings at high temperatures or corrosive media, low-speed friction bearings, etc.
