SK Chemicals SKYPEL P128DF Thermoplastic Polyester Elastomer
Categories:	Polymer; Thermoplastic; Elastomer, TPE; Polyester TPE
Material Notes:	SKYPEL P128DF is a thermoplastic polyester elastomer resin superior heat resistance. SKYPEL P128DF with a medium 28D hardness based on shore D scale is widely used for injection molding and extrusion applications. And SKYPEL P128DF is also available to over mold TPU, PC, ABS, PC/ABS alloys. Properties: Excellent mechanical properties such as high tensile strength and strain at break. High resistance to creep, impact, and flex-fatigue. Excellent flexibility at low temperature. Fast crystallization to reduce the cycle time of injection process. Processing: SKYPEL P128DF should be sufficiently dried prior to processing. For effective drying using dehumidifying dryer, it should be held for 2 to 3 hours at 100 ? or overnight at least 70 ?. Pre-dried SKYPEL P128DF in aluminum bag is also available. Tensile property tests on ASTM Type IV dumbbells diecut from injection molded slab 2mm thick. Crosshead speed 50 mm/min.
