HFO-1234ze has found another use as an innovative blowing agent for integral skin polyurethane foams, providing excellent foam performances and minimizing the environmental impact.
Different from insulating foams, polyurethane integral skin foam products are composed of a two-part polyurethane system: a flexible, lightweight foam core encased in a thick outer “skin” providing a soft touch feeling, that is created in a single molding process. Integral Skin Foams has a wide use, e.g. car steering wheels, or office furniture armrests.
HFO-1234ze has a very low GWP of 1, is non flammable and is not classified as a volatile organic compound (atmospheric ozone precursor) by the US EPA.
