Sponge and Foam


Optimize the performance of your components by matching your application to the right sponge or foam material.  Applications include gaskets, seals, pads, cushions, packaging, electrical-, thermal-, and acoustic insulators, and vibration isolation and damping.

Ensuring a proper seal, achieving precise compression set resistance, protecting against dust or the environment (e.g. UV, moisture)—all of these requirements can be accomplished when the proper material is used in the creation of your die-cut components.
