BEAD FOAM COMPRESSION MOLDING METHOD FOR LOW DENSITY PRODUCT
摘要:
Disclosed is a method for molding a foamed article, such as a midsole or outsole for footwear, in which a desired amount of thermoplastic polyurethane foam beads are placed in a compression mold in the shape of the article and the mold is brought to a peak temperature of from about 130° C. to about 180° C. over a period of from about 300 to about 1500 seconds, then cooled to from about 5° C. to about 80° C. over a period of from about 300 to about 1500 seconds within about 30 seconds after the peak temperature is reached. The foamed article made by the method has a density of from about 0.1 to about 0.45 g/cm3.
