The term microcellular rubber refers to blown rubber that is used for seals, die-cuttings, buffers, blanks and profiles. Low-cost alternatives to microcellular rubber are synthetic rubber or crosslinked PE foam, which is what we mainly process.
Besides PE foam and synthetic cellular rubber, polyethylene foam or cell polyethylene is also frequently understood as being microcellular rubber. Crosslinked PE foam can often be found in craft supply outlets and in the retail trade under the designation 'microcellular rubber'. Although none of these materials are microcellular rubber, they often provide a low-cost and useful alternative to microcellular rubber.
