The main characteristics of PVC film and its use

by：LINYANG 2020-06-15

PVC film is a polymer material that has been born since the development of plastic. As a polymer, this PVC film has the characteristics of light weight, transparency, ease of use, and thin thickness, so it is also called PVC transparent film. Introduce PVC, which is polyvinyl chloride ???? Polyvinyl chloride Poly (Vinyl Chloride), CAS number: 9002-86-2; white bag or light yellow powder; relative density is 1.4; solubility: low relative molecular weight, easily soluble in ketones, esters and chlorinated hydrocarbons Like solvents, high molecular weight is difficult to dissolve; PVC is obtained by polymerization of vinyl chloride monomer. At present, there are four kinds of PVC production methods in China: suspension polymerization, emulsion polymerization, micro-suspension polymerization and bulk polymerization. Some companies use suspension polymerization technology, which uses acetylene and hydrogen chloride as raw materials to synthesize vinyl chloride monomer from the two, and then polymerizes to produce polyvinyl chloride Ethylene. This is the main feature of pvc and its use.
