Classification Of Plastic Bottles

- May 23, 2018-

According to the different usage characteristics of various plastic bottles, plastic bottle manufacturers usually divide plastic bottles into three types: general plastic bottles, engineering plastic bottles and special plastic bottles.

General plastic bottles generally refer to plastics with high yield, wide use, good formability and low price. There are five major kinds of raw materials for plastic bottles, namely, polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and propylene green butadiene styrene copolymer (ABS). They are all thermoplastic.

Engineering plastic bottle generally refers to the ability to withstand a certain external force, with good mechanical properties and high and low temperature performance, good dimensional stability, can be used as the engineering structure of plastic, such as polyamide, polysulfone and so on. In engineering plastics, it is divided into two categories: general engineering plastics and special engineering plastics. General engineering plastics include polyamide, polyoxymethylene, polycarbonate, modified polyphenylene ether, thermoplastic polyester, ultra-high molecular weight polyethylene, methyl amyl polymer, vinyl alcohol copolymer and so on. Special engineering plastics also have cross-linked non crosslinked components. The crosslinked types are polyamino bismaleimide, polythree azine, crosslinked polyimide, heat-resistant epoxy resin finger etc. Non crosslinked types are polysulfone, polyethersulfone, polyphenylene sulfide, polyimide, polyether ether ketone (PEEK), etc.

Special plastic bottles generally refer to plastics with special functions, which can be used in special applications such as aviation and aerospace. For example, fluoroplastics and organosilicon have special functions such as high temperature resistance and self lubrication. The reinforced plastics and foam plastics have special properties such as high strength, high cushioning and so on. These plastics all belong to the category of special plastics.
