Because it is widely used in the manufacture of diving materials, in recent years, with the continuous reduction of costs and the vigorous promotion of many professional finished products manufacturers, it has become a new type of material with expanding application fields.

A rubber name: styrene-butadiene rubber, which is formed by copolymerization of butadiene and styrene. According to the production methods, it can be divided into emulsion polymerized styrene-butadiene rubber and solution polymerized styrene-butadiene rubber, which has good comprehensive properties and chemical stability.
