1, PP, polypropylene, low price, easy to modify, generally used in the housing of household appliances, car bumpers, and so on. At present, many of the required parts are made with modified PP and are widely used.
2, PE, polyethylene, low price, not easy to modify, generally in toys, plastic bags, catering, car tables and chairs and other applications, soft texture, and not easy to modify, but the price is very low, so the application is general
3, PS, polystyrene, this material hardness is good, but the benzene ring combustion toxicity is large, generally in engineering and disc applications more, there are some containers.
4, PA, polyamide, commonly known as nylon, because of its good strength application, in engineering machinery, automotive space all have a good application, fiber can be used as the foundation of the fabric.
5, ABS, acrylonitrile styrene butadiene copolymer, the surface brightness is very high, generally as high-grade electrical appliances shell many.
6, PVC, PVC, itself flame retardant, good strength, and low price, the application is also very wide, but the burning of toxic gases, also will be a lot of restrictions, in the pipe, sheet, cable materials, containers and so on a lot of applications.
