Butyl Rubber (IIR)
Butyl rubber is a synthetic rubber, a copolymer of isobutylene with isoprene. The abbreviation IIR stands for Isobutylene Isoprene Rubber.
Grades of IIR are:
- Regular Butyl
- Bromo Butyl
- Chloro Butyl
Uses: Butyl rubber is used for the bladders in basketballs, footballs, soccer balls and other inflatable balls to provide a tough, airtight inner compartment. IIR sealant is used for rubber roof repair and for maintenance of roof membranes especially around the edges. Butyl rubber is one of the most robust elastomers when subjected to chemical warfare agents and decontamination materials. It is a harder and less porous material than other elastomers, such as natural rubber or silicone, but still has enough elasticity to form an airtight seal, hence it is used to create seals in gas masks and other protective clothing. It is used in Adhesive, Sealent, Tank lining, Fibre proofing etc.
