often abbreviated as CIIR (Chlorinated Isobutylene-Isoprene Rubber), is a synthetic rubber that is derived from butyl rubber through the chlorination of its polymer structure. This modification enhances the material’s compatibility with other materials and improves its adhesion to various substrates. Chlorobutyl rubber retains many of the properties of butyl rubber, such as gas impermeability and chemical resistance, while offering better adhesion properties. Here are some key characteristics and common uses of chlorobutyl rubber.
Chlorobutyl rubber has significantly improved adhesion properties compared to standard butyl rubber. It can bond more effectively with various substrates and materials.
Like butyl rubber, chlorobutyl rubber maintains excellent impermeability to gases. It is often used in applications requiring airtight seals or barriers.
Chlorobutyl rubber offers good resistance to a wide range of chemicals, acids, and bases, making it suitable for applications in contact with corrosive substances.
It exhibits good resistance to weathering, UV radiation, and ozone, making it suitable for outdoor applications.
Chlorobutyl rubber remains flexible at low temperatures, which is important for applications in cold environments.

Gaskets and O-rings
Chlorobutyl rubber is valued for its improved adhesion properties while retaining the gas barrier characteristics and chemical resistance of butyl rubber. It is used in various applications where strong bonding or adhesion to different surfaces is a key requirement.
