The main raw material of vinyl double head is dimethyl dichlorosilane, but the auxiliary raw material needs to use metal sodium and vinyl chloride monomer. The use of metal sodium is a national key control products, with certain access barriers. Vinyl double head is mainly used as head agent to produce high temperature vulcanized silicone rubber, additive silicone rubber, silicone gel and vinyl silicone oil and other products. Through the different amount and way of addition, the vinyl double head can effectively control the degree of polymerization and improve the performance of the product. Looking to the future, the development of high temperature silicone rubber industry to drive the demand for vinyl double head steadily increase, however, the development of electronic field with vinyl double head is an important industrial direction of the company, the corresponding downstream is mainly vinyl silicone oil silicone rubber, liquid silicone rubber, LED potting glue, etc..
