Bellofram Dense (Solid Silicone) Products
Our multiple lines, extensive expertise in custom formulations, and tool-making capabilities allow us to produce dense silicone across an almost limitless range. Our dense compounds meet the ASTM D 2000 specifications, ranging in hardness from 30 Shore “A” to 80 Shore “A” durometer. Dense 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.
