Butyl rubber is impermeable to air with outstanding resistance to gases, vapors, heat aging, oxygen, ozone, sunlight, abrasion and tearing. It offers excellent resistance to alkalis and acids and this material is good for electrical insulation, automotive parts and construction.
Attributes of Butyl:
- Air tight and gas impermeable
- Low glass transition temperature
- Good ozone resistance
- Good vibration damper
- Slow aging material
Uses of Butyl:
- Shock mounts and Butyl O-Rings
- Sealant for rubber roof repair, construction sealants, hoses and mechanical goods.
- Tubeless tire liners, inner tubes.
- Stoppers for glass bottles, medicine bottles, and pharmaceuticals
- Pond and Tank liners
