Butyl Rubber
BUTYL RUBBER
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.
Certain materials must be able to tolerate frequent shaking. Butyl rubber can sustain damage over time without breaking down. This resilient material may withstand impact or handle hardship without compromising seals or hindering other job duties.
One of the greatest compounds for reducing vibration and noise is butyl rubber. Because of the material’s well-known durability and flexibility, shock mounts, suspension bushings, and other components that need to reduce vibration and noise production in an application are a good fit for it.

ADVANTAGES OF BUTYL RUBBER
Butyl, like other specialized materials, has a few unique properties that set it apart and make it the preferred option for a wide range of industries and applications. To put it simply, butyl rubber is long-lasting because of the following characteristics:
- Physical robustness
- Low permeability to moisture and gases
- Absorption of shock
- Several resistances
APPLICATIONS
- 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
