Butyl rubber (IIR) is an excellent choice for shock absorption and has low moisture and gas permeability. It has great resistance to heat, aging, weather, ozone, chemical attack,
abrasion and tearing conditions. It is resistant to phosphate ester-based hydraulic
fluids and has excellent electrical properties. Butyl is not suitable for petroleum-based
Applications include seals, gaskets, hose, tire inner tubes and sportball bladders.
