Rubber Compound Materials

Butyl Rubber
[IIR – Isobutylene Isoprene Rubber]

Cloth Inserted Rubber

[Cloth Inserted Sheet, C/I, Fabric Reinforced]
A rubber sheet impregnated with a fabric ply; various rubber compounds can be used.


Diaphragm Sheet

A flexible membrane that permits motion between a stationary and a moving part while maintaining a tight seal. Diaphragm sheets may be made of a variety of compounds and/or contain fabric plies for strength.

EP Rubber
