Elastollan? 1175AW
熱塑性聚氨酯彈性體（聚醚）
產品說明:
Elastollan? 1175AW is a polyether-based thermoplastic polyurethane (TPU) containing a plasticizer. It contains a non-halogenated flame retardant and is rated UL-94 V-0 in vertical flame test for wall thicknesses of 0.9 mm - 1.1 mm, UL-94 V-2 for wall thicknesses of 1.2 mm and 3.0 mm. It exhibits excellent abrasion resistance, toughness, transparency, very good low temperature flexibility, hydrolytic stability and fungus resistance. It has excellent damping characteristics and outstanding resistance to tear propagation. Elastollan? 1175AW is supplied uncolored in pellet form.
