Lightweight reinforced RIM polyurethane substrates are increasingly being specified for fully covered automotive applications such as interior door panels, instrument panels, and package shelves. In addition to offering a 30-40 % weight reduction over conventionally used substrate materials, consolidation in manufacturing steps are achieved by molding direct to polyvinylchloride (PVC), polyurethane (PU) and/or textile coverings. Weight reduction and consolidation of manufacturing steps lead to considerable part cost savings. Styling trends toward complex, deep drawn door panels, integrated with instrument panel modules, are easily fulfilled with low pressure RIM. Existing RIM capital used to produce RRIM fascia, cladding, and body panels is suitable to manufacture low density RRIM substrates (LD-RRIM).
