Butyl Manufacturing in Business

Butyl is a synthetic rubber made from isobutylene and isoprene. It features excellent impermeability and good flex properties, making it great for applications requiring airtight rubber. Its first major application was tire inner tubes, but it has expanded to include uses like fiber optics, gloves, O-rings, caulks & sealants, ball bladders, gaskets, speakers, flashing, explosives and more.
