Exaflex® TPU 95A is an ester-based thermoplastic polyurethane with a hardness of 95 Shore A. It combines high tensile strength at break (42 MPa) with exceptionally high elongation of 572 % and an elastic modulus of 108 MPa — a combination rare for the 95A class, characterizing the material as stiff yet with pronounced elastic recovery.

Tear strength of 60 N/mm (ISO 34-1) and high damping characteristics make the material suitable for conveyor components, wear profiles, drive profiles and parts under cyclic loading. Very good low-temperature flexibility and resistance to mineral oils, greases and many solvents. As an ester-based TPU, it requires drying before processing to a residual moisture content below 0.02 %.

Exaflex® TPU 65D-EF is an easy-flow modification of polyurethane with a hardness of 65 Shore D. Its reduced melt viscosity allows thin-walled parts and complex geometries to be filled at lower injection pressure, while the improved demolding profile shortens mold-opening time and reduces mold wear.

Its basic set of physical and mechanical properties matches Exaflex® TPU 65D — hardness 65 Shore D, tensile strength 55 MPa, elongation 250 %, tear strength 200 kN/m (Die C). It is intended for series molding of complex parts where a short cycle and clean release of the molding from the cavity are critical.

Key properties

• Easy Flow — reduced melt viscosity for thin-walled parts and complex cavities
• Improved demolding — lower risk of molding deformation, shorter cycle
• Reduced mold wear thanks to lower injection pressure
• Hardness 65 Shore D (ASTM D2240)
• Tensile strength 55 MPa, elongation 250 % (ASTM D412)
• Tear strength 200 kN/m, Die C (ASTM D624)
• Low abrasion loss — 65 mm³ per ASTM D5963 (Method A non-rotate)
• Tg −22 °C (DSC), resistance to hydrolysis and mineral oils

Applications

• Thin-wall injection molding: technical housings, gears, vanes, complex boxes with ribs and lugs
• Multi-cavity molds with long melt flow paths
• Automotive electronics parts, medical housings, sports protective gear
• Series moldings with tight cycle and ejection tolerances

Processing recommendations
