Hot Sale Gum Industrial Butyl Flexible Natural Rubber Sheet

Butyl rubber is a kind of synthetic rubber, which is synthesized from isobutylene and a small amount of isoprene. Finished products are not easy to leak and are generally used to make tyres. Butyl rubber is a copolymer of isobutylene and isoprene. Butyl rubber is a kind of synthetic rubber, which is synthesized from isobutylene and a small amount of isoprene. It is generally used to make tyres. In the field of building waterproofing, butyl rubber has been widely used to replace asphalt in the name of environmental protection.

Butyl rubber has good chemical stability and thermal stability, and the most outstanding are air tightness and water tightness. Its air permeability is only 1/7 of that of natural rubber and 1/5 of that of styrene-butadiene rubber, while its steam permeability is 1/200 of that of natural rubber and 1/140 of that of styrene-butadiene rubber. Therefore, it is mainly used for manufacturing various rubber products such as inner tubes, steam pipes, water tyres, dam bottom and gaskets.
