A unique foaming process is briefly described and the properties of polyolefin foams produced by this process are reviewed. The influence of parameters such as foam density, crosslink level and cell structure are discussed, and in particular the effect of polymer type is examined. Foam grades based on metallocene polyolefins have recently been introduced, and the properties of these materials are compared with those of foams based on other polymers.
