Polyurethane(TPU) Tube for Medical 1, Tight tolerance extrusions 2, Excellent biocompatibility 3, Excellent performance

Extruded Polyurethane(TPU) Tube 

[Material Description]

         Thermoplastic Polyurethane(TPU), is an (AB)n type linear polymeric chains in block-structures. A is a polyester or polyether with molecular weight (1000-6000), B is a diol containing 2-12 straight chain carbon atoms. The chemical structure of AB segments is linked by diisocyanates, usually which is MDI. The currently available TPUs can be divided mainly in two groups: polyester-based TPUs and polyether-based TPUs. TPU is white ruleless spherical or cylindrical particles with relative density of 1.10-1.25. The relative density of polyether-based TPUs is smaller than that of the polyester-based TPUs.

[Properties]

                 Excellent wear resistance

                 Excellent elasticity and ductility, outstanding carrying capability, impact resistance & shock absorption

                 Outstanding low temperature performance: TPU has very low glass transition temperature; it has good elasticity, flexibility and other excellent physical properties.

                 Wide hardness range: from 60A to 90D.

                 Excellent biocompatibility
