Description

Butyl Rubber (IIR) Butterfly Valve Liners / Soft Valve Seats

Butyl Rubber (IIR):

Butyl Rubber is formed by the polymerization of isobutylene with small amount of isoprene. Because the movement of methyl groups is less than other polymers, it has less gas transmittance, greater resistance to heat, sunlight and ozone, and better electrical insulation. Good resistance to polar capacitive agent, the general using temperature range is -54 ~110 degree.
