Polypropylene resin composition, useful e.g. for creating fabric texture, comprises a polypropylene resin, a polypropylene elastomer, ethylene-alpha-olefin copolymer, an inorganic filler, cellulose fiber and a volcanic rock

摘要

Polypropylene resin composition comprises: a polypropylene resin containing a homopolypropylene, a propylene-ethylene copolymer, or a high crystalline polypropylene; a polypropylene elastomer prepared by reacting 20-85 wt.% of ethylene-propylene rubber and 15-80 wt.% of homopolypropylene; an ethylene-alpha -olefin copolymer; an inorganic filler; at least one cellulose fiber consisting of nylon, polyethylene terephthalate, polybutylene terephthalate or cellulose; and a volcanic rock. Polypropylene resin composition comprises: a polypropylene resin containing a homopolypropylene, a propylene-ethylene copolymer prepared by polymerizing 50-99 wt.% of propylene monomer and 1-50 wt.% of ethylene monomer, or a high crystalline polypropylene prepared by polymerizing 90-99.9 wt.% of propylene monomer and 0.1-10 wt.% of 4-10C alkylene monomer; a polypropylene elastomer prepared by reacting 20-85 wt.% of ethylene-propylene rubber and 15-80 wt.% of homopolypropylene; an ethylene-alpha -olefin copolymer; an inorganic filler; at least one cellulose fiber consisting of nylon, polyethylene terephthalate, polybutylene terephthalate or cellulose; and a volcanic rock.
