POLYPROPYLENE-BASED RESIN WITH HIGH GROSSINESS BY CONTROLLING THE CONTENT OF ETHYLENE PROPYLENE RUBBER AND ETHYLENE PROPYLENE RUBBER

摘要

PURPOSE: A polypropylene-based resin is provided to increase glossiness by controlling the kind, content and property of a mixing component without application of additives for increasing glossiness, and to reduce manufacturing costs in absence of additives.;CONSTITUTION: A polypropylene-based resin is mixed with ethylene propylene and homo-polypropylene. The content of the ethylene-propylene rubber is 5~15 weight%. In the ethylene-propylene rubber, the content of the ethylene is 25~50 mole %. The inherent viscosity of the ethylene-propylene rubber is 2.0~5.0 dl/g. The melt index of the polypropylene-based resin is 1~40 g / 10 minute.;COPYRIGHT KIPO 2010
