Butyl Rubber is a synthetic rubber, a copolymer of isobutylene with isoprene. The product is impermeable to air and used in many applications requiring an airtight rubber. Butyl Rubber has good flex properties, resulting from low levels of unsaturation between long poly isobutylene segments. It also has a high level of heat resistance and excellent low-temperature flexibility.
Butyl Rubber is used in the manufacture of tyre inner liners, automotive tubes, pharmaceutical closures, ball bladders, adhesives, sealants, vibration mounts, electrical fluids and lubricants among others.
