Estane® thermoplastic polyurethane TPU compounds are specifically designed for fast, easy injection molding of large and small parts. The softer Estane® TPU compounds, in the shore hardness range of 70A to 90A, have a low modulus of elasticity and excellent retention of flexibility at very low temperatures. The harder Estane® TPU compound materials, in the shore hardness range of 50D to 70D, have a high modulus of elasticity, and excellent lowtemperature impact strength.
