1. Wear resistance
It is more than five times more wear-resistant than natural rubber and is one of the preferred materials for wear-resistant products.
2. Tensile properties
The tensile strength is as high as 70MPa, and the elongation at break can be as high as 800%.
3. Tearing property
TPU film has higher tear resistance and better tear strength than common rubber and plastic.
4. Zigzag performance
TPU products can maintain excellent bending resistance in different environments, which is one of the best choices in polymer materials.
5. Hydrolytic resistance
TPU has good water resistance under turbidity, and will not be significantly hydrolyzed for 1-2 years; Polyester series will be completely hydrolyzed after being soaked in 50 ℃ water for half a year or 70 ℃ for 3 weeks or 100 ℃ for 3-4 days, which is one of the reasons why TPU film is suitable for environmental protection materials.
6. High temperature resistance and oxidation resistance
TPU has good antioxidant capacity. Generally, the temperature resistance of polyester series can reach 130 ℃, and that of polyether series can reach 90 ℃.
7. Oil resistance and drug resistance
TPU is a kind of strong polar polymer material, which has little affinity with non-polar mineral oil and is hardly eroded in fuel oil and machine oil. Among TPU products, polyester series products have better oil resistance.
8. Low temperature performance
TPU film has very good low temperature resistance, which can usually reach - 40 ℃. It is a good substitute for PVC.
9. Air tightness
TPU is very easy to use high frequency or hot pressing to weld, so it is widely used in inflatable products. Generally speaking, the air tightness of polyester products is better than that of polyether products.
10. Biomedical properties
TPU film has excellent biocompatibility, non-toxic, no allergic reaction, no local irritation, no heat source, so it is widely used in medical, health and other related products, as well as sports, protective equipment.
