Abstract: Expanded polypropylene (EPP) beads with a density of 10-200 g/l and a particle diameter of 1-10 mm, contain 0.1-10 wt.% homogeneously dispersed graphite particles. Independent claims are also included for production processes for EPP beads by: (a) impregnating graphite-containing polypropylene (PP) granules with 2-40 wt.% volatile blowing agent in aqueous suspension under pressure at 100-160 deg C, and then releasing the pressure; and (b) extruding PP together with graphite and 2-30 wt.% volatile organic blowing agent at 120-240 deg C and granulating the extruded product.

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.
