Introducing Bellofram Elastomers

Bellofram Diaphragm and Bellofram Silicones, two legendary names, become one

Bellofram Elastomers is the new single entity created by joining together Bellofram Diaphragm and Bellofram Silicones. The division’s creation offers a single access point for customers seeking elastomers of every type.

Bellofram Elastomers brings together two legendary names. Bellofram Diaphragm invented the original rolling diaphragm in 1950 and has continued to lead in the manufacturer of frictionless and leak-proof rolling seals that handle pressures, temperatures, and stroke lengths over an extremely wide range. Bellofram Silicones is an industry supplier of closed cell silicone sponge and the only source for sheets skived from buns. It offers bulk extrusion footage, bulk sheet products, and small to medium runs.

The Bellofram Elastomers value proposition is its ability to offer three highly specialized capabilities from one manufacturer, the only company able to do so.

First, Bellofram Elastomers manufactures closed cell silicone sponge in both extruded and molded form, product vital for high-temperature applications. Second, it is the only company in the world that makes closed cell silicone sheets. Skived from buns, there is no rind on either side, for the lightest density, lowest closure force silicone material. And third, the company makes formed fabric-reinforced diaphragms, among the few manufacturers in the world to do so.

No one company does all three, except Bellofram Elastomers.

Products from both divisions serve different applications, but there is considerable market overlap. Bellofram Elastomers was created to give customers a single point of entry to the world of elastomer options available with the Bellofram name. All products from Bellofram Elastomers share the benefits of precision manufacturing, custom material formulations, and unmatched institutional knowledge of applications.
