Polyurethane Rigid Foam Slab

Rigid PUR foam is a highly crosslinked closed celled thermoset material of low density. The combination of these reactions leads to the formation of the macromolecular skeleton with tailor-made properties. Polyurethane is a type of polymer offered in both solid and foam form. Specifically, polyurethane foam has an open cellular structure to achieve this form and it can be rigid or flexible. Some of the common types of polyurethane foam are memory foam, high resilience foam and high density foam.
