5204 - Closed Cell Silicone Sponge Extruded, Compression Deflection, 5-9
Bellofram Silicones extruded closed cell silicone sponge profiles are used when your difficult sealing problems require a combination of complex gasket shapes and extreme flexibility. Our diemaking capabilities allow us the ability to produce cords, rectangals, tubes, and any complex geometric shape. Our in house mixing gives you the choice of materials with a wide compression deflection rating from ASTM D 1056 2D1 soft density to ASTM D 1056 2D5 extra firm density. The self-forming skin enhances the profiles resistance to water absorption. Need to meet a BMS requirement? Bellofram is a certified supplier of BMS 1-23 and BMS 1-60 products. We offer a flame retardant version in each density range that will make sealing possible in extreme environments. An FDA version is also available when FDA compliance is required. Available in any color to aide to the aesthetics of your assembly.
