Tailor-Made Thermoplastic Polyurethanes for the Shoe Industry

Part design:

For applications in sports & leisure industry the Desmopan ? product family offers transparent aromatic grades, highly abrasion-resistant and aliphatic light-stable variations. Besides, these products are free of plasticizers and halogen.

The polyether-based aliphatic TPU grades are ideal for manufacturing sports shoe soles. They are lightfast and can therefore also be produced in bright, fashionable colors. They also combine low density, high elasticity and flexibility, allowing the production of thinner shoe soles with less weight. A further benefit is their excellent adhesion to most materials that are used to produce sports shoes. This combination of properties offers a new, superior alternative to polyether block amides in this market segment.

The abrasion-resistant Desmopan? grades were specially designed for the injection molding process of sports shoe soles and sport shoe studs. However, they are also suitable for standard shoe applications as, for example, ladies shoe heels. The polyester-based TPU products are UV-stabilized, resistant to hydrolysis and have hardnesses from 85 Shore A to 53 Shore D.

Further advantages of these materials are:

• Cost-effective production with short cycle times: the produced parts can be easily removed from the mold even with large wall thicknesses.
• Reduced abrasion loss: up to 30 percent compared to standard grades

Desmopan 795U弹性体的物理性能包括密度、线性膨胀系数、摩擦系数、气体扩散系数、传热系数、玻璃化转变温度、熔点、熔化热、比热容和特性粘度等。TPU的密度大约在1.10～1.25之间，在同等硬度时聚醚型TPU密度比聚酯型TPU低。TPU密度决定于软段种类、分子量、硬段或软段含量以及TPU聚集态。这一部分讨论TPU与橡胶和塑料的比较、软段类型的影响、TPU分子量的影响、软段取代基的影响和硬段含量的影响。
