Butyl Reliance Impramer R 1675

Butyl rubber is a synthetic polymer, a copolymer of isobutylene with isoprene. The key advantages butyl rubber offers is superlative air-barrier performance with superior 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. Impramer R 1675 is offered as white to light amber color bale and has 0.92 as typical specific gravity.
