Butyl Rubber

Butyl Rubber is a unique synthetic rubber that is highly impermeable to air,

making it an ideal material for use in applications that require airtight seals.

The polymer is formed by the copolymerization of isobutylene and small

amounts of isoprene. This results in a polymer with low levels of unsaturation,

which provides excellent flexibility and resistance to cracking.

One of the most important properties of Butyl Rubber is its excellent air

impermeability. This makes it an ideal material for use in tyre inner liners,

where it is used to prevent the escape of air from the tyre. It is also widely

used in the manufacture of automotive tubes, pharmaceutical closures, and

ball bladders, where it provides excellent sealing and durability.

Butyl Rubber is also used in a variety of other applications, including

adhesives, sealants, vibration mounts, electrical fluids, and lubricants. Its high

level of heat resistance and excellent low-temperature flexibility make it an

ideal material for use in harsh environments. In addition, Butyl Rubber has

excellent resistance to ozone and UV light, which makes it an ideal material

for outdoor applications.
