Texin® 1209
TPU(热塑性聚氨酯)
科思创 (原拜耳)(Covestro)
产品描述
Texin 1209 resin is an aromatic polyether-based thermoplastic polyurethane; it can be processed by injection molding or extrusion.
Texin 1209 resin is characterized by very good hydrolysis resistance, good low temperature flexibility, resiliency and impact strength, high moisture vapor transmission rates and is plasticizer free. Texin 1209 natural color resin complies with FDA food-contact regulations 21 CFR 177.1680 (Polyurethane Resins) and 177.2600 (Rubber Articles Intended for Repeated Use), subject to the limitations of these and any other applicable regulations. Applications include soft touch over-molding, roof linings, seals, membranes, films, rigid/flexible composite systems and sport shoe soles. As with any product, use of Texin 1209 resin in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
