BELLOFRAM Elastomers

THE NAME THAT MATTERS

Bellofram Elastomers brings together two legendary names, Bellofram Diaphragm and Bellofram Silicones.

Bellofram Diaphragm invented the original rolling diaphragm in 1950 and has continued to lead in the manufacture 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 closed cell silicone sponge sheets skived from buns. It offers bulk extrusion footage, bulk sheet products, and small to medium runs.

Although products from both divisions serve different applications, 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. Order with confidence that you will receive an exacting solution with industry-leading expertise.

THREE IN ONE: THE BELLOFRAM ELASTOMERS’ DIFFERENCE

Three highly specialized capabilities. Only one manufacturer.

What’s the Bellofram Elastomers difference?

There are actually three of them. Three highly specialized capabilities that, when you put them together, makes us the only source in the world for all three.

We manufacture closed cell silicone sponge in both extruded and molded form. This product is vital for high-temperature applications in which superior physical properties must be maintained as temperatures rise.
We are 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.
We make formed fabric-reinforced diaphragms, among the few manufacturers in the world to do so. The deeper the curve, the higher the degree of difficulty. When you need a top-hat diaphragm that’s fabric reinforced, only we will say 'no problem.'

No one does all three. Except Bellofram Elastomers.

Customers know they can come to us with their toughest challenges and we will deliver right-sized solutions they often can't find anywhere else in the world. Bellofram Elastomers brings the power of three together.
