BELLOFOAM closed-cell silicone sponge sheeting from Bellofram Silicones is designed to support a variety of industrial, manufacturing, gasketing, insulation, sealing, and padding requirements in automotive, aerospace, factory floor, and industrial environments. Offered in a variety of densities, thicknesses, and pigment matched colors, the proprietary BELLOFOAM is uniquely produced in bun form. According to the company, the bun provides the core from which sheets are skived horizontally, resulting in a product with higher consistency and 25% less weight than other closed-cell silicone sponge sheeting available on the market. This method also allows Bellofram Silicones to produce up to 2.00 in (50.8 mm) thick sheets, depending upon customer requirements. The unique closed-cell design of BELLOFOAM is designed around the ASTM D 1056 specification for prevention of water absorption. Three density ranges are available to meet requirements of ASTM D 1056 2D1, 2D2, and 2D3 (AMS 3195).
