Borealis Daplen™ EF221AE Polypropylene, 20% Mineral Fiber Reinforced
Categories:	Polymer; Thermoplastic; Polypropylene (PP); Polypropylene, Mineral Reinforced
Material Notes:	Daplen™ EF198HP is a 17% mineral filled polypropylene compound intended for injection molding. This material has an excellent balance between impact strength and stiffness and gives a good surface quality. Special Features: High scratch resistance Low gloss High purity Excellent surface appearance Applications: Daplen EF198HP has been developed especially for the car industry to be used in automotive interior parts. Dashboards Door panels and pockets Pillar trims Seat claddings Center consoles Automotive interior applications Values determined on standard injection molded specimens conditioned at 23°C and 50% relative humidity after at least 96 hours storage time. To avoid residual humidity from transport or storage, the material should be pre-dried approximately 2h at 80°C. Information provided by Borealis AG
