Alternative to flame pretreatment – Openair® Plasma pretreatment of exclusive instrument panels without masking
The panel consists of three material layers: a glass-fibre reinforced plastic core, a polyurethane foam layer, and a slush-molded skin (made of PVC or TPU). The core parts are made of injection-molded fibre-reinforced polypropylene. This non-polar plastic needs to be pretreated to make its surface receptive to adhesion processes.With the conventional flame technique, all zones where no foam is to be applied must be masked with thermally stable materials.
