About PVC

关注:32 发表时间:2019-09-19 20:10:36

Polyvinyl chloride is the world's third-most widely produced synthetic plastic polymer, after polyethylene and polypropylene

About 40 million tonnes are produced per year. 

PVC comes in two basic forms: rigid (sometimes abbreviated as RPVC) and flexible. 

The rigid form of PVC is used in construction for pipe and in profile applications such as doors and windows. 

It is also used in making bottles, non-food packaging, food-covering sheets, and cards (such as bank or membership cards). 

It can be made softer and more flexible by the addition of plasticizers, the most widely used being phthalates

In this form, it is also used in plumbing, electrical cable insulation, imitation leather, flooring, signage, phonograph records, inflatable products, 

and many applications where it replaces rubber. With cotton or linen, it is used to make canvas

Pure polyvinyl chloride is a white, brittle solid. It is insoluble in alcohol but slightly soluble in tetrahydrofuran.
