According to the molecular structure of synthetic resin, plastic raw materials mainly include thermoplastic and thermosetting plastics. For thermoplastic plastics, plastics that are plastically heated repeatedly: mainly PE/PP/PVC/PS/ABS/PMMA/POM/PC/PA And other common raw materials. Thermosetting plastics mainly refer to plastics made from heat-hardened synthetic resin, like some phenolic plastics and amino plastics, not commonly used. According to the scope of application, there are general plastics such as PE/PP/PVC/PS, engineering plastics such as ABS/POM/PC/PA, etc. There are also some special plastics such as high temperature resistant, high humidity and corrosion resistance and others. Some plastics modified for special purposes. Crash Helmet,Bulletproof Helmet,Ballistic Helmet Dacheng Advanced Material Co., Ltd. , http://www.bullet-proofs.com
