REACTIVE DILUENT FOR ONE OR TWO COMPONENT PU FOAMS

摘要

The invention is directed to a polymer foam precursor composition comprising 1 to 60%, preferably 5 to 30 % by weight, of a biodiesel obtained by transesterification of vegetable oils. The polymer foam is advantageously a polyurethane foam and the biodiesel is a mixture of methyl and or ethyl fatty acid esters. The biodiesel is a latent hardener and/or extender and/or liquid filler. The composition is advantageously used in pressurized vessel or aerosol type cans.
