TPU film is one of the preferred plastic materials for wear-resistant products, is more than five times wear-resistant than natural rubber. TPU film hardness is an indicator of the material’s ability to resist deformation, nicks and scratches.
The hardness of the TPU film affects the wear resistance.
The lower hardness of the TPU film, smooth texture and soft hand feel.
The higher hardness of the TPU film, the better wear and scratch resistance of TPU film.
Excessive hardness of TPU film is easy to be brittle. There is a certain relationship between TPU hardness and temperature. When cooling from room temperature to the sudden change temperature (-4~-12°C), little hardness change. The TPU hardness suddenly increase if sudden change temperature, be harder and lower elasticity.
POLYSAN factory produces and supplies high quality TPU film, hardness range from 75A to 95A. It is recommended to select the appropriate TPU film hardness according to actual application requirements to maintain its good elasticity and wear resistance. TPU has been widely used in shoe materials, ready-made clothing, mobile phone cases, inflatable toys, water and underwater sports equipment, medical equipment, fitness equipment, car seat materials, umbrellas, suitcases, leather bags, etc.
