A rubber material produced by copolymerizing isobutylene with a small amount of isoprene. Butyl is variously manufactured into sheet goods, blended with other rubber materials, and is often used to make sealants and adhesives.
(chemical identification:isobutylene isoprene-IIR):is produced by copolymerizing isobutylene with small amounts of isoprene. These rubbers have excellent impermeability to gases, outstanding dielectric properties, good resistance to tearing, good aging properties at elevated temperatures and good chemical stability.
Synthetic rubber or man-made rubber. Invented during the 1950's for use in everything from car tires to chemical warfare suits. Considered a durable fabric, it has good barrier to a limited number of chemicals. Go to top
