What Does CIIR Stand For?

CIIR stands for Chlorinated Isobutylene Isoprene Rubber

CIIR, or Chlorinated Isobutylene Isoprene Rubber, is a synthetic rubber compound characterized by its excellent resistance to heat, ozone, and aging. It is produced through the chlorination of isobutylene-isoprene rubber, enhancing its performance in various applications. CIIR is commonly used in the automotive and industrial sectors for products such as tires, seals, and gaskets, where durability and resilience are essential. Its unique properties make it suitable for applications requiring high resistance to chemicals and environmental factors.
