Abstract

An intumescent silicone rubber composition is provided having an expandable intumescent material present in the composition by up to 20% by weight, a polyorganosiloxane oil present in an amount from about 10% to about 40% by weight of the composition, a hydrated alkali metal silicate present in an amount: of up to 80% by weight of the composition and a silicone elastomer binder present in an amount from about 4%
to about 30% by weight of the composition. The result is a very effective and relatively inexpensive composition which when used as firestop material around combustible pipe, such as PVC or ABS, readily meets the test criteria set forth under ASTM Standard E-814.
