Material Notes:
Daplen KB4436 is a 30% mineral and elastomer modified polypropylene compound intended for injection molding. Daplen KB4436 is a material with excellent impact/stiffness ratio. Thanks to its low thermal expansion this material is suitable to mold parts requiring low change of dimensions over a broad temperature range. The product is optimized to give good surface aesthetics.Daplen KB4436 has been developed for body side moldings, rocker panels, and window frames.Information provided by the Manufacturer.
