Abstract

PURPOSE: To manufacture the material for seals having uniform continuous bubbles by placing a thermoplastic elastomer powder and a soluble salt fine powder in a concave matrix and molding them, and then eluting the salt part.
CONSTITUTION: A mixture powder consisting of a thermoplastic elastomer powder (such as a styrene-butadiene copolymer) of a particle diameter of 6W200 meshes and 0%W60% of a soluble salt fine powder (such as NaCl is placed a concave matrix 2 having a metal frame 1, and a convex lid 3 is covered on the upper part of the metal frame 1. Then, the mixture powder is pressed and heated, and then molded by sintering and cooled. Thereafter, the obtained sintered body is washed with water, and the soluble salt part is eluted.
