Butyl Rubber

Butyl Rubber is a synthetic rubber that is derived from the polymerization of Isobutylene with Isoprene (composition of 98% of Isobutylene and 2% of Isoprene). The first major application of butyl rubber was for the manufacturing of tire inner tubes. To this day, this remains the most significant segment of its market.

Derivatives of Butyl Rubber:

• Bromo Isobutylene Isoprene – BIIK (also called Bromo Butyl Rubber): derived from reacting Butyl Rubber with Bromine in a continuous process.
• Chloro Isobutylene Isoprene – CIIK (also called Chloro Butyl Rubber): derived from reacting Butyl Rubber with Chlorine in a continuous process.
