PROBLEM TO BE SOLVED: To make it possible to manufacture an injection-molded body, the surface sliding properties of which are improved and the pollutive volatile components of which are remarkably reduced by a method wherein fine superpolymeric polyethylene particles are employed as sprinkling powder for preventing pellets from agglutinating. SOLUTION: In an injection molding, in which pellet-like thermoplastic elastomeric material is employed, fine superpolymeric polyethylene particles are employed as sprinkling powder for preventing pellets from agglutinating at the supplying of the pellet. In this case, the preferable particle diameter of superpolymeric polyethylene I is set to be 50μm or less. By employing this fine polyethylene particle, the surface sliding properties of a molded body become favorable. Even when the fine polyethylene particle is formed on the exterior of a structure, the hang-up and adhesion with an external factor become small. Further, a volatile component or a pollutive component, which is harmful to the member for a precision apparatus and develops from the molded body, can be remarkably reduced. |
