Butyl Rubber Sheet (IIR)

Butyl Rubber (IIR) is a synthetic rubber made from isobutylene with a small amount of isoprene. Known for its exceptional impermeability to gases, excellent flexibility, and outstanding resistance to heat, chemicals, and weathering, IIR is widely used in applications requiring airtightness and durability.

Its unique properties make Butyl Rubber ideal for inner liners in tires, pharmaceutical stoppers, sealants, and protective clothing. IIR's low gas permeability helps maintain tire pressure, enhancing safety and performance.

Additionally, Butyl Rubber exhibits excellent damping characteristics and good resistance to aging, oxidation, and ozone, contributing to its long service life in demanding environments.

Key Properties

✅ Exceptional gas and moisture impermeability – ideal for airtight and watertight seals

✅ Excellent resistance to acids, alkalis, and ozone

✅ Good heat resistance and aging stability

✅ Low rebound and vibration damping – performs well in insulation and seal applications
