Do you know the advantages of these 10 TPU films?

It is precisely because of the many advantages of TPU film that it has a wide range of applications. For example, the advantages of TPU film are better in some clothing, such as shoe upper linings, thermal underwear, elastic bands and medical breathable tapes. The fabric laminated with TPU film has the effect of waterproof, warm, moisture permeable and breathable, which is very suitable for sports clothing. Now let me know what are the advantages of TPU film!

1. Wear resistance It is five times more wear-resistant than natural rubber, and it is one of the main 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. Tear performance TPU film has high tear resistance, and its tear strength is better than that of commonly used rubber and plastic.

4. Bending performance TPU products can maintain excellent bending resistance in different environments, and it is one of the best choices among polymer materials.

5. Hydrolysis resistance TPU has good water resistance under turbidity, and no obvious hydrolysis will occur in 1-2 years. The polyester series will be completely hydrolyzed when soaked in water at 50 degrees Celsius for half a year, or 3 weeks at 70 degrees Celsius, or 3-4 days at 100 degrees Celsius, 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 oxidation resistance. Generally, the temperature resistance of polyester series can reach 130 degrees Celsius, and the temperature resistance of polyether series can reach 90 degrees Celsius.

7. Oil resistance and chemical resistance TPU is a kind of strong polar polymer material, which has little affinity with non-polar mineral oil, and is almost not eroded in fuel oil and mechanical oil. Among them, TPU products are also Polyester series products have better oil resistance.

8. Low temperature performance TPU film has very good low temperature resistance, usually reaching -40 degrees Celsius, and is a good substitute for PVC.

9. Air tightness TPU is very easy to weld by high frequency or hot pressing, so it is widely used in inflatable products. Generally speaking, the air tightness of polyester series products is better than that of polyether series products.

10. Biomedical performance TPU film has excellent biocompatibility, non-toxic, non-allergic, non-local irritation, non-pyrogenic, so it is widely used in medical, health and other related products as well as sports and protective equipment .
