Butyl Sealants: Virgin Raw Materials vs. Reclaim
Introduction to Butyl Sealants Butyl sealants, based on butyl rubber (IIR – Isobutylene-Isoprene Rubber), are extremely versatile materials that play a key role in many industrial sectors, including construction, heavy industry, and renewable energy. Their unique molecular structure, resulting from the copolymerization of isobutylene with a small amount of isoprene,
