METHOD FOR MANUFACTURING POWDER OF THERMOPLASTIC ELASTOMER COMPOSITION |
摘要 |
PROBLEM TO BE SOLVED: To provide a manufacturing method by which powder of a thermo plastic elastomer composition having an average particle diameter of 700μm or less as converted in terms of a sphere can be manufactured without deteriorat ing the productivity by an underwater cut process. SOLUTION: This manufacturing method comprises the steps to manufacture the powder of the thermoplastic elastomer composition having an average particle diameter of 700μm or less as converted in terms of a sphere by the underwater cut process. The powder of the thermoplastic elastomer composition manufactured by this method meets the following conditions (a) and (b): (a) The temperature of the thermoplastic elastomer composition immediately before passing through a die is 120-220 deg.C. (b) The temperature of the die is 230-350 deg.C.
