CONDUCTIVE POLYPROPYLENE-BASED FOAMED RESIN PARTICLES EXHIBITING EXCELLENT MOLDABILITY AND CONTAMINATION RESISTANCE, METHOD FOR PRODUCING POLYPROPYLENE-BASED FOAMED RESIN PARTICLES, AND POLYPROPYLENE-BASED FOAMED RESIN MOLDED BODY

摘要

A resin composition contains 100 parts by weight of a polypropylene-based resin. 17.6 parts by weight or more and less than 33.4 parts by weight of conductive carbon black, and 0.1 parts by weight or more and 3.0 parts by weight or less of a water-soluble organic substance, the resin composition having a melting point Tm of 145°C or more and 155°C or less as measured by a differential scanning calorimetry (DSC) method, and having a temperature difference ΔT of 50°C or more between the melting point Tm and the crystal melting start temperature Tl in the DSC curve.
