Abstract
An interior trim panel comprises a flexible polyurethane skin layer, an intermediate resilient polyurethane foam layer and a rigid polyurethane foam substrate. The flexible polyurethane skin layer and intermediate resilient polyurethane foam layer are formed as an expanded thermoplastic urethane (TPU) shell in a slush molding process. The rigid polyurethane foam substrate is then foamed in place on the shell in a substrate forming mold. This produces an environmentally friendly, long lasting interior trim panel that can be manufactured economically without any need for plasticizers or adhesive coatings.
