ETPU for runways
about TPU
ETPU, short for expanded thermoplastic polyurethane, is a new - type foaming material with excellent performance. It is widely used in runways due to its unique properties
ETPU particles can effectively accumulate and release energy when subjected to force. The unique polymer honeycomb structure provides strong shock - absorption and rebound, enabling the runway to maintain excellent elasticity all year round. When athletes run on the runway, ETPU can be squeezed, expanded, and rebounded under each step, reducing the damage to the knees and ankles during exercise.
ETPU - made runways have excellent aging resistance. They are not easy to yellow or harden, and the elasticity is not easy to lose. They can still maintain good physical properties between 65 degrees Celsius and minus 20 degrees Celsius. After 1000 - hour accelerated aging, the physical properties decrease by less than 1%, which meets the international and domestic standards. They are suitable for professional competitive events with frequent use of spike - shoes and have a long service life.
ETPU - based runways are suitable for a variety of scenarios, such as school playgrounds, fitness areas in parks and high - end residential communities, private basketball court training grounds, etc.. They can meet the needs of different groups of people, providing a more comfortable, safe, and environmentally friendly sports space.
