Bellofram Silicone Solid Molded Products
Molded products from Bellofram Silicones offer solid silicone construction, available in 30 to 80 shore “A” durometer. Material choices range from economical commercial grade to high-performance low-temperature, and flex- and tear-resistant grades. They can be tinted to most colors.
Our in-house mixing of custom formulations allow us to produce solid silicone molded products to confirm to ASTM, SAE, MIL-STD, and other military and industrial specifications. A fully approved NSF 51 version produced with FDA ingredients is also available, in applications where FDA compliance is required. For rush jobs, we can match one of our compounds with a profile of your design to find a quick solution to even your most complex sealing needs.

Solid Extruded Silicone, Closed Cell Silicone Sponge Sheeting and Molded Silicone Rubber Products
Bellofram Silicones, a division of the Bellofram Group of Companies and a member of the Bellofram Elastomers group, is an industry leader in the design, development and manufacture of extruded silicone, silicone sponge foam sheeting, and molded rubber products, including specialty rubber compounds. We have taken the very best technology, chemistry, and rubber know-how from antecedents Mold Ex, MTI Specialty Silicones, and Groendyk Manufacturing to become a one-stop shop for sealing, gasket, and insulation requirements. Our products include:
Closed Cell Silicone Sponge and Solid Silicone Extruded Products
Our multiple extrusion lines and extensive expertise in custom formulations and tool-making capabilities allows Bellofram Silicones to produce closed cell silicone sponge and solid silicone rubber extrusions in almost limitless shapes, colors, and hardnesses. Our commercial closed cell silicone sponge compounds are designed to meet the ASTM D 1056 spec, range in density from 2D1 soft density to 2D5 firm density. Our Solid compounds are designed to meet the ASTM D 2000 spec, ranging in hardness from 30 Shore “A” to 80 Shore “A” durometer. Both sponge and solid silicone compounds are also available in flame retardant and NSF/ANSI 51 compliant versions. All silicone compounds are designed to exceed requirements of a wide range of industrial, aerospace, and MIL-specs.
BELLOFOAM™ Closed Cell Silicone Sponge Rubber Sheeting
Bellofram Silicones produces our proprietary silicone sponge rubber material in bun form, from which sheets are cut. This method is unique in the silicone sheeting industry, and allows us to offer the lightest-weight high-consistency closed-cell silicone sponge foam sheeting in the world. Unique manufacturing methods allow us to reduce weight by 25%, resulting in less expensive material. This method also allows us to produce up to 0.50” thick sheets, far exceeding the industry maximum of 0.188”. Our fluorosilicone sheets and buns meet requirements of AMS 3323. Three hardness ranges, including one fire retardant version and color pigment matching allows us to offer exact customer specification for sealing, gasketing, and insulating needs. Customers may also purchase a bun to skive their own sheets. Pressure-sensitive adhesives may be added, to assist in customer assembly.
Bellofram Silicones offers silicone elastomer compression molding to create products that incorporate closed-cell and dense solid construction methodologies. Closed cell and dense formulations are strictly limited to silicone. These types are also available in a wide variety of elastomers, including nitrile, EPDM, FKM, SBR, fluorosilicone, and other materials. Various fabrics may be integrated within the process to enhance strength and limit stretch. All Bellofram Silicones proprietary formulas are developed to ensure their complete conformance with a wide range of industrial, NSF/ANSI 51 approved, aerospace, and MIL-spec requirements.
