Borealis Daplen™ PB4432 TPO Compound (discontinued **)
Categories:	Polymer; Thermoplastic; Elastomer, TPE; Thermoplastic Olefinic Elastomer (TPO); Polypropylene (PP); TPO
Material Notes:	Daplen PE4432 is a 10% mineral and elastomer modified polypropylene compound intended for injection molding. Daplen PE4432 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. This product is optimized to give good surface aesthetics. Daplen PB4432 has been developed especially for bumpers, spoilers and exterior trims. Information provided by the Manufacturer.
