Abstract

PURPOSE: To enable the cell diameter to be largely changed and obtain a continuous foamed body having a coarse cell diameter, by a method wherein the first intermediate product obtained by temporarily lowering the pressure in a mold while the decomposing rate of a foaming agent is within a specified range is made to decompose the rest in the second process.
CONSTITUTION: The compound obtained by compounding ethylene (co)polymer with both a foaming agent and a crosslinking agent is placed in a mold capable of being closed up, and pressurized and heated for a given period of time. After a given period of time has passed, it is removed or the pressure is reduced to regulate the cell diameter. To change the cell diameter largely, the decomposing rate of the foaming agent is to be 5W80%. Said first intermediate product is heated in a mold which is not airtight in order to decompose the residual foaming agent and crosslinking agent, thereby the second intermediate product having a coaraw cell diameter is obtained. Destroying independent cells by means of compression in the third process permits a continuous foamed body to be obtained.
