Texin® 3041
TPU(热塑性聚氨酯)
科思创 (原拜耳)(Covestro)
产品描述
Texin 3041 is an aliphatic polyether-based thermoplastic polyurethane of approximately 55D Shore hardness. It can be processed by injection molding or extrusion.
Texin 3041 resin is characterized by outstanding clarity, inherent resistance to hydrolysis, a high moisture vapor transmission rate, weatherability and flexibility. It is stabilized against degradation due to heat and UV exposure. Typical applications of Texin 3041 include coated fabrics, tarps and rain gear, optical lenses, flexible windows and outdoor signage. As with any product, use of Texin 3041 resin in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.
