Butyl Rubber(IIR)

Butyl Rubber(IIR)

Butyl rubber is composed by copolymerizing isobutylene, which with small amounts of isoprene.

It is like EPDM possessing excellent resistant to chemical and polar fluid, outstanding electrical insulation and good ozone resistance.

The special properties of butyl rubber are low gas and moisture permeability and high shock absorption.

These properties have made butyl rubber the polymer choice in a variety of applications.
