UNBRPAD

UNBRPAD is a kind of uncured non-silicone rubber for manufacture of pressure caul sheets, flexible mandrels and rubber tooling. UNBRPAD provide an uniform pressure on the vaccum bag side of the part to improve part quality during autoclave processing. UNBRPAD can undertake high temperature similar to silicone rubber but will not cause silicone contamination.
