Thermoplastic polyurethane Exaflex TPU 90A
Description
Exaflex TPU is a range of high-tech polyurethanes with diverse properties that provide mechanical strength, abrasion resistance and slip resistance. The wide range of available hardness grades makes Exaflex TPU an ideal material for footwear, transport-industry components and the automotive industry.
Advantages
- Resistance to wear and tearing.
- Flexibility: High flexibility at low temperatures; retains elasticity and shape.
- Chemical resistance: Excellent resistance to oils, greases and many solvents.
- Thermal stability: Performs effectively over a wide temperature range, from -40 to +80 °C.
- UV resistance: Does not lose its properties or color under ultraviolet exposure.
Applications
Used for the production of dampers, protective coatings, shock-absorbing elements and seals. Manufacture of soles and inserts. Production of flexible tubing, cable products, connectors and seals. Flexible elements in electronic devices.
