  polyethylene (PE) （PE） polyethylene (PE) is plastics industrial in output/production volume most high product types. polyethylene (PE) is transparent or semi transparent, light crystallization property plastics, tool has excellent low temperature resistance property can （ most low use temperature degree can 达－70~－100℃）, electrical insulation property, chemical stability property good, can resistant large more acid alkali 侵蚀, heat resistant. polyethylene (PE) using/adopting injection molding, blow molding, and other methods processing.

     polypropylene (PP) （PP） polypropylene (PP) is propylene polymerization thermoplastic property plastics, usually is color, semi transparent solid 体, 无臭无毒, density is 0.90~0.919克/ cm 3, is most light general purpose plastics, its advantages is tool has in water in resistant features, corrosion resistant, strong/high degree, rigid property and transparent property ratio polyethylene (PE) good, disadvantages is low temperature resistance impact property 差, easy aging, can separation through modified and add additives add 以改进. polypropylene (PP) production methods has method, liquid versus method and gas versus method 3 types.

     polyvinyl chloride (PVC) （PVC） polyvinyl chloride (PVC) is chlorine ethylene polymerization plastics, through add increase agent, its hardness can large degree 改变. it made formed hard products soft products has applications. polyvinyl chloride (PVC) production methods has polymerization method, emulsion polymerization method and polymerization method, 以悬浮 polymerization method is 主.

     polystyrene (PS) （PS） general purpose polystyrene (PS) is styrene polymer, appearance transparent, has disadvantages, therefore, through add poly butadiene can made formed resistant impact property polystyrene (PS) （HTPS）. polystyrene (PS) main/primary production methods has polymerization, polymerization and solvent liquid polymerization.

    ABS resin is acrylonitrile － butadiene － styrene types mono 体共同 polymerization material, 简称ABS terpolymer. this type of plastics due to its separation A（ acrylonitrile ）, B（ butadiene ） and S（ styrene ） in formed in ratio/proportion different, and manufacturing methods 差异, its property has very large 差别. ABS适 combined injection molding and pressure processing, its applications main/primary is production this type products.
