Butyl Rubber Rolls is a synthetic rubber, a copolymer of isobutylene with isoprene. The abbreviation IIR stands for Isobutylene Isoprene Rubber. Butyl Rubber is impermeable to air and used in many applications requiring an airtight rubber.
Butyl Rubber is a very good general purpose rubber used for many applications and is a high strength rubber material, known for its excellent resistance to oils and high vapor chemicals. The most unique characteristic of Butyl rubber is that its permeability to air is 70% better than that of most other rubber materials and for this reason the industry uses it for tire tubes and tubeless tire inner liners. Butyl rubber rolls are used where a formed gasket may be needed. Butyl rubber rolls can also be used for piecing together a formidable gasket to prevent fluids from leaking and in many gasket applications in the industrial arena to include pipe saddles, flange gaskets and piping supports / pipe padding. Butyl Rubber resists heat aging, is resistance to UV Rays and chemical erosion. DiscountRubberDirect.com’s Butyl Rubber has a high resistance to abrasion and carries above average tear resistance making it common to use in marine environments and electrical applications. These properties have made butyl rubber the polymer choice in a variety of applications.
