Q:What material is the packing belt made of?

Polypropylene is a thermoplastic resin made by the polymerization of propylene. According to the location of the methyl group into isotactic polypropylene (isotactic, polyprolene), random polypropylene (atactic polypropylene) and syndiotactic polypropylene (syndiotactic, polypropylene) three kinds.The arrangement of methyl groups on the same side of the molecular backbone is called isotactic polypropylene. If the methyl group is arranged in random order on both sides of the backbone, it is called atactic polypropylene, and when the methyl group is arranged alternately on both sides of the backbone, syndiotactic polypropylene is called. In general industrial polypropylene resins, the isotactic structure is about 95% and the remainder is atactic or syndiotactic polypropylene. Industrial products are based on isotactic substances. Polypropylene also includes copolymers of propylene with a small amount of ethylene. Usually translucent, colorless solid, odorless, non-toxic. The melting point can be as high as 167 DEG C because of the highly crystalline structure. Heat resistance and corrosion resistance, products can be steam disinfection is its outstanding advantages. Small density, is the lightest general plastic. The disadvantages are low temperature resistance, low impact and easy aging, but can be overcome by modification.
