Properties

Chlorobutyl rubber is an isobutylene-isoprene copolymer derived from reacting butyl rubber with chlorine in a continuous process. Compared with regular butyl rubber, Chlorobutyl rubber provides an improved compression set and better resistance to heat, ozone and flex fatigue.

Low permeability to air, gases and moisture.

Vibration damping.

Low glass transition temperature, similar to regular butyl.

Wide vulcanization versatility.

Fast cure rates.

Processing safety: no nitrosamines or nitrosamines precursors.

Good adhesion and compatibility to other rubbers.
