Pearlthane® 12T92E is a special polyester-based TPU, supplied in form of translucent, colourless pellets, combining hardness with excellent processability and low temperature performance. This grade has been specially designed for mechanically demanding applications where excellent mechanical properties are required, such as timing belts Pearlthane® 12T92E can be extruded into profiles, belts, tubes and film. In the case of injection moulding, this grade is only recommended for certain applications, e.g. when large, hard-to-fill mould cavities are used. |
