摘要：PURPOSE: A polypropylene-based resin composition is provided to set contents of fluorine resin and inorganic filler to improve melting tension of the resin composition and to have a simple mixing and molding process through an extruder. CONSTITUTION: A polypropylene-based resin composition comprises 100.0 parts by weight of a polypropylene resin or high melting tension polypropylene resin; 0.1-20 parts by weight of a fluorine resin; and 0.1-20 parts by weight of inorganic filler. The weight average molecular weight of the polypropylene resin is a propylene homopolymer or copolymer which has a weight average molecular weight of 300,000 or more and a melt index(ASTM D1238) of 0.1-10 g/10min. The polypropylene-based resin composition has a melting tension of 0.3 N or more.
