Bellofram Closed Cell Silicone Sponge Products
Bellofram Silicones extruded closed cell silicone sponge profiles are used when difficult sealing problems require a combination of complex gasket shapes and extreme flexibility.
Our full in-house die-making capabilities allow us to produce cords, rectangles, tubes, and other complex geometries. Our in-house mixing provides a choice of materials with a wide compression deflection rating, ranging from ASTM D 1056 2D1 soft density to ASTM D 1056 2D5 extra firm density, with a temperature range of -85° to 400°F for continuous use.
The self-forming skin enhances the profile’s water absorption resistance. We are a certified supplier of BMS 1-23 and BMS 1-60 products. We offer a flame-retardant version in each density range to make sealing possible in extreme environments. A fully certified NSF/ANSI 51 version produced from FDA ingredients is available, in applications where FDA compliance is required. Bellofram Silicones extruded closed cell silicone sponge profiles are available in any color.
