Manufacturing Process
Cross-Linked polyolefin foam bun stocks are commercially produced by batch processes employing a chemical blowing agent. The process using CBA evolved from the old rubber foam process and is sometimes called the compression molding process since the foam shape is formed in a mold loaded on a hot press.
A homogenous mixture of the polymer, cross-linker, and blowing agent is formed into a slab, heated in a mold on a press so that the cross-linking agent can cross-link the polymer and the blowing agent can decompose, and expanded by a release of pressure.
