Abstract: Expanded polypropylene (EPP) particles with a density of 10-150 g/l and dia. of 2-10mm are based on a gel-free and partly crosslinked polymer (I) of more than 50 wt.% propylene and the polymer chains are linked by polyfunctional organic cpds. (II). Also claimed is a method for making the EPP particles.

Abstract: A process comprises producing expanded polyolefin particles by impregnating polyolefin granules with a volatile blowing agent in suspension under pressure, and then releasing the pressure. The suspension medium has a lower density than the polyolefin granules and the suspension is practically free from suspension agents.

Abstract: The invention relates to a method for producing expanded polyolefin particles, according to which polyolefin granulate is impregnated with a volatile expanding agent in suspension under pressure and then relaxed. The suspension medium has a lower density than the polyolefin granulate and the suspension is practically free of suspension stabilisers.
