Thermoplastic elastomer powder for powder molding, powder molding method using the same and molded article thereof. |
摘要 |
<p>A thermoplastic elastomer powder for powder molding, comprising an elastomer composition of an ethylene- alpha -olefin copolymer rubber and a polyolefin resin, wherein the elastomer composition has a complex dynamic viscosity eta *(1) as measured at frequency of 1 radian/sec. in dynamic viscoelasticity measurement at 250 DEG C, of 1.5 x 10<5> poise or less, a Newtonian viscosity index n calculated from the following formula by using the complex dynamic viscosity eta *(1) at a frequency of 1 radian/sec. and the complex dynamic viscosity eta *(100) at a frequency of 100 radian/sec. of 0.67 or less, and a hardness (shore D) of 45 or less: <MATH> ,</p> |
