Sibur Regular Butyl Rubber (IIR)
Butyl rubber is a synthetic polymer, a copolymer of isobutylene with isoprene. The key advantage butyl rubber offers is superior air-barrier performance with excellent flex properties. Butyl Rubber abbreviated as IIR (Isobutylene-Isoprene copolymer) is extensively used to manufacture tire’s Inner Tube. It offers matchless ozone & weather resistance along with heat stability.
