POLYURETHANE FOAM WITH INTEGRAL SKIN AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain low-density integral skin foam having excellent physical properties such as impact resistance, etc., and to provide a method for producing the same. SOLUTION: The method for producing integral skin foam comprises using a specific blowing agent substantially free from water and/or a polyoxyalkylene polyol having 15-45 mgKOH/g hydroxy value and≤0.03 meq/g total unsaturation degree. The integral skin foam having≤0.55 g/cm3foam density and excellent impact resistance is obtained without prolonging a demolding time. COPYRIGHT: (C)2004,JPO&NCIPI
