a brief analysis of the properties of tpu films

1.tpu filmthe wear resistance of rubber is more than five times that of natural rubber, making it one of the first choices for wear-resistant products;

2. tensile properties: the tensile strength is as high as 70mpa and the elongation at break is as high as 800%;

3.tear performancetpu filmit has high tear resistance and its tear strength is better than commonly used rubber and plastic;

4.bending performanceTPUthe product can maintain excellent bending strength in different environments, which is one of the best choices among polymer materials;

5. hydrolysis resistance tpu has good water resistance under turbidity. no significant hydrolysis will occur within 1-2 years. the polyester series will be completely hydrolyzed after being soaked in water at 50°c for half a year or soaked at 70°c for 3 weeks or 100°c for 3-4 days. this is also one of the reasons why tpu film is suitable for environmentally friendly materials;

6. high temperature resistance and anti-oxidation tpu has good antioxidant properties. the heat resistance of ordinary polyester series can reach 130 degrees celsius, and the heat resistance of polyether series can reach 90 degrees celsius;

7. oil and chemical resistance tpu is a highly polar polymer material. it has little affinity for non-polar mineral oils. it is virtually non-corrosive in fuel and machinery oils. in,tpu film manufacturersthe tpu products are also polyester series products with better oil resistance;

8. low temperature performance tpu film has good low temperature resistance and can usually reach -40 degrees celsius. it is a good substitute for pvc;

9. air-tight tpu is very easy to weld using high frequency or hot pressure, so it is widely used in inflatable products. generally speaking, polyester series products have better air tightness than polyether series products;

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