THERMOPLASTIC ELASTOMER POWDER COMPOSITION FOR POWDER MOLDING AND POWDER MOLDING METHOD USING THE SAME COMPOSITION AND ITS MOLDED BODY

摘要

PURPOSE:To obtain the title composition having excellent powder fluidity for a long period and capable of providing a good molded article by adding fine powder to thermoplastic elastomer powder of ethylene-alpha-olefin based copolymer rubber and polyolefin based resin, etc. CONSTITUTION:100 pts.wt. thermoplastic elastomer powder being powder of a thermoplastic elastomer consisting of a composition of an ethylene-alpha-olefin based copolymer rubber and polyolefin based resin or powder of a thermoplastic elastomer consisting of a partially crosslinked type composition of ethylene-alpha- olefin based copolymer rubber and polyolefin based resin, being <=1.5X10<5> poise in complex hinematic viscosity eta...(1) in 1 readin/sec frequency at 25 deg.C and being <=0.67 in Newton viscosity index calculated from eta...(1) and complex hinematic viscosity eta...(100) at 100 radian/sec frequency is blended with 0.05-20 pts.wt. fine powder having <=30mum average particle diameter to provide the objective thermoplastic elastomer powder composition for powder molding.
