Extruded thermoplastic polyurethane (TPU) results from co-polymerization of two or more monomers. One monomer is used to provide the hard, crystalline features, whereas the other monomer produces the soft, amorphous features. Combined these, form a thermoplastic material that exhibit properties similar to the hard and vulcanized elastomers.
TPU range currently covers the two basic types: Polyester TPU and Polyether TPU based on aromatic diisocyanates.
Because of its toughness and versatility, as well as generally higher price tag than other TPE's, urethane is typically used for parts requiring a high level of performance. These applications frequently demand a flexible material with a high degree of flex resistance, wear ability and durability. Particularly at lower temperatures, other materials do not provide this combination of properties.
