Nanoclay Modification and Compound Formulation for Foaming Linear Polypropylene

IntroductionLinear polypropylene is not ideal for making foams for sealing purposes due to poor melt strength. The attempts to overcome this limitation by cross-linking a portion of the linear polymer or by adding a long chained branched polymer have resulted in unwanted side effects, such as a reduction in recyclability. Additionally, long chain branched...
