Title: METHOD FOR PRODUCING POLYURETHANE BOOTS
Abstract:
The invention relates to a method for producing polyurethane boots, wherein a) organic polyisocyanates are mixed with b) polyols, c) chain extender, d) blowing agent, e) catalyst, and f) optionally other auxiliary agents and/or additives to form a reaction mixture and is introduced into a mold by means of only one injection, which mold comprises the sole and the upper of the boot, and is allowed to fully react to form a polyurethane boot, characterized in that at least one catalyst comprising a tertiary amine and sebacic acid is used at a molar ratio of 1 : 0.19 to 0.27.
