Abstract

PURPOSE: To prepare the titled foam having milky white beautiful appearance and particular specific gravity and hardness, containing a large amount of bonded urea, and suitable as a cushioning material, etc., by foaming a composition composed of specific amounts of polyol, isocyanate, catalyst and foaming agent, etc.
CONSTITUTION: 100pts.wt. of a polyol is compounded with 0.13W0.3pts.wt. of an isocyanate catalyst or an amine catalyst (e.g. triethylenediamine), 7.0W15.0pts.wt. of water as a foaming agent, and 2.0W3.75pts.wt. of a silicone oil as a foam stabilizer. The composition thus obtained is foamed by stirring, and cured to obtain the objective foam having a specific gravity of 0.008W0.016g/cm3 and a hardness of ≥7kg/314cm2.
EFFECT: Since harmuful substances such as trichlorofluoromethane, etc. are not used in the process, there is no trouble of environmental pollution.
