Borealis Daplen™ AK4504 TPO Compound (discontinued **)
Categories:	Polymer; Thermoplastic; Elastomer, TPE; Thermoplastic Olefinic Elastomer (TPO); Polypropylene (PP); TPO
Material Notes:	Daplen AK4504 is a 30% mineral and elastomer modified polypropylene compound intended for injection molding. Daplen AK4504 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 AK4504 is designed for acoustic applications, climate control housing, and cowl vent grill Information provided by the Manufacturer.
