Urethane]-foam moulding compsn. - with poly:ol-component contg. fluorohydrocarbon, for moulding prods. with integral skin

摘要

In a urethane-foam moulding compsn. with a first liq. contg. a polyol component and a second liq. contg. an isocyanate component, the novelty is that the first liq. is mixed with a blowing agent of fluorohydrocarbon contg. at least one C-H bond and a b.pt. not higher than 20 deg.C and the polyol component is a combination of a number of polyether-polyols having a viscosity of 70-100 Pa.s. USE/ADVANTAGE - Used for producing interior parts of vehicles, e.g., arm-rests, head-rests, ect., and can be used for a wide range of uses, e.g., cushions, mattresses, pieces of furniture, etc. A lower mixt. of hydrochlorofluorohydrocarbons and hydrofluorocarbons is reduced. The foam prods. have good physical properties and damage to the ozone layer in the atmos. is reduced.
