Silicone Products Silicone Sponge Sheets

BELLOFOAM™ from Bellofram Silicones is the lightest high-consistency closed cell silicone rubber sheeting material on the market. It contains truly closed cells, as determined by the stringent ASTM-D-1056 water absorption under vacuum method, eliminating wicking. The formulation and construction of these sheets allows for continuous operation of materials over a wide temperature range of -85° to +400°F, with outstanding recovery after compression. The sheets skived from buns can be supplied from 0.125” to 2.00” thickness, or buns can be skived into sheets using a customer’s own equipment.

There are three available ASTM-D-1056 hardness versions of the standard sheet, including one with the necessary enhanced fire retardant additives to meet UL94 V-0 specifications, and a second version with fluorosilicone sponge properties, meeting the requirements of AMS 3323. With these and other available options, BELLOFOAM™ silicone foam rubber sponge sheets cover a wide range of demanding physical, temperature, and chemical environments.
