Molded Cellular Rubber

Colonial, DPP has manufactured over four billion (4,000,000,000) custom molded cellular/foam/sponge rubber seals and gaskets for the world's major industries. Molded cellular rubber is a chemically-blown rubber that can be formulated for open or closed cell applications. Our molded products continually create value for our customers by employing a multi-level one piece seal that efficiently replaces built-up and two material die cut seals. Cellular rubber can create a leak-proof barrier against noise; vibration; dust; water and other fluids or chemicals, when urethanes and ethylene materials under perform. Another advantage includes maintaining superior performance even when compressed 20% or 50% due to variations in stack up conditions between individual assemblies.

Our extensive lab and formulating capabilities enable Colonial to design and compound materials to meet a vast range of physical properties including resistance to chemicals, temperature, weather, and exceeding ASTMD1056 water absorption requirements.

Materials include but are not limited to: EPDM; Neoprene; SBR; Nitrile; rubber to metal bonding; rubber to plastic bonding and cellular rubber to dense rubber bonding.
