Thermoplastic elastomer powder and powder slush molding method using the same
摘要:
A thermoplastic elastomer powder for powder slush molding, comprising an elastomer composition of an ethylene-α-olefin copolymer rubber and a polyolefin resin, wherein said elastomer composition has a complex dynamic viscosity η*(1) as measured at a frequency of 1 radian/sec in a dynamic viscoelasticity measurement at 250°C, of 1.5 x 10⁵ poise or less, a Newtonian viscosity index n calculated from the following formula by using the complex dynamic viscosity η*(1) at a frequency of 1 radian/sec and the complex dynamic viscosity η*(100) at a frequency of 100 radian/sec. of 0.67 or less: n = [logη*(1) - logη*(100)]/2.
