Abstract
PURPOSE: To prevent internal discoloration during the preparation of soft polyurethane foams and to prevent discoloration after preparation, due to heat, ultraviolet rays, etc., by adding TiO2 in addition to the conventional compounding components.
CONSTITUTION: Use is made of a composition for soft polyurethane foams which is prepared by adding 0.1W5pts.wt. per 100pts.wt. of polyol, of TiO2 powder, about 1W30μ in diameter, in addition to a polyol, a polyisocyanate, a catalyst, a blowing agent, etc. The TiO2 prevents effectively discoloration due to internal evolution of heat during foaming. A further effect to prevent discoloration is obtained by combining the TiO2 powder with a phenolic antioxidant such as 2,6-di-tert-butyl-4- methylphenol, the so-called BHT.
