Abstract

A sound absorbing moulding consists of an open pored and/or textile gas porous substrate. The latter is impregnated with a thermally hardenable binding agent and a hydrophobic and oleophobic agent. The impregnating agent consists of a fluoro carbon resin and the binding agent consists of a polyacrylate resin which has duroplastic characteristics after cross linking has taken place. The substrate consists of polyurethane foam or polyether foam.
