Background of TPSIU Product Development
Compared to general rubber and plastic materials, TPU has the advantages of environmental friendliness, comfort, durability, and diverse processing methods. It is widely used in many fields such as electronic injection molding, sports and leisure, cables, films, pipes, hydraulic seals and transmissions, and military industry. However, TPU materials have limitations in chemical resistance, softness and touch, and resistance to dirt, which restrict their application in smart wearable materials.
TPSiU is a complex multiphase new material formed by thermoplastic polyurethane elastomer (TPU) and organosilicon. TPSIU material combines the durability, wear resistance, and coating molding process options of TPU, as well as the flexibility, UV resistance, and chemical resistance brought by organosilicon technology. TPSIU elastomer can precisely adjust the color to meet customer requirements, and can maintain its excellent and lasting aesthetic characteristics even in demanding wearable device applications. Wearable device manufacturers can use the flexibility and silky feel of TPSIU elastomer to improve consumer comfort.
Performance Characteristics of TPSIU Products
TPSIU material combines the durability, wear resistance, and coating molding process options of TPU, as well as the flexibility, UV resistance, chemical resistance, and dirt resistance brought by organosilicon technology. The main characteristics are as follows: silky touch, wear resistance, high tensile and tear strength, easy coloring and printing, high and low temperature resistance, easy cleaning, excellent demolding properties, low odor, and environmental friendliness.
