Butyl Special CIIR High Temp 70 Duro

Resistant to Compression Set and High Temperatures

Chlorobutyl (CIIR) and Isobutylene Isoprene (IIR) compounds provide superior gas permeation and excellent weather resistance. They are also useful for their energy absorption properties. Food grades are available.

Butyl rubbers do not provide good petroleum oil or fuel resistance and are not especially good at compression set resistance.
