General Sealing Products / Sponge, Foam & Cellular Grades

Custom Grades including MilSpec, Def STAN, NSN, AS & DTD available. Below is a sample of common grades. Contact us for your unique requirements.

Natural Rubber sponge has a unique cell structure when compared to most other blown rubber sponges. When blown you get an Open Cell structure composed of connected cells that allow air or gas to pass through when compressed.

This sponge structure offers good compression set characteristics, and typically rebounds faster than closed cell sponges. We offer a range of materials from soft to extra firm and these can be classed VO fire rated or with Cryogenic insulation options.
