a brief discussion on the advantages and usage directions of tpu film

tpu filmadvantages?TPUit is increasingly popular among people because of its superior performance and environmental protection concept. currently, tpu can be a substitute for pvc wherever pvc is used. tpu film can not only be bonded to various fabrics, but can also be used to produce products with clear outlines and stable dimensions using vacuum thermoforming. with the continuous improvement of domestic environmental protection awareness, the application of tpu is becoming more and more widespread. among them, the areas with the fastest growth rate are: shoe upper linings, thermal underwear, transparent underwear, transparent shoulder straps, elastic bands and medical breathable tapes. in addition, there are also a large number of applications in the field of clothing fabric lamination. the fabrics laminated with tpu films have waterproof, warm, moisture-permeable and breathable effects, and are very suitable for sports clothing.

tpu filmadvantage

1. wear resistance

it is more than five times more wear-resistant than natural rubber and is one of the 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 commonly used rubber and plastics.

4. twist performance

tpu products can maintain excellent bending resistance in different environments and are one of the best choices among polymer materials.

5. hydrolysis resistance

tpu has good water resistance under turbid conditions and will not undergo obvious hydrolysis in 1-2 years.

polyester series will be completely hydrolyzed if soaked in water at 50 degrees celsius for half a year, 70 degrees celsius for 3 weeks, or 100 degrees celsius for 3-4 days. this is one of the reasons why tpu films are suitable for environmentally friendly materials.

6. high temperature resistance and antioxidant

tpu has good anti-oxidation ability. 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 highly polar polymer material that has very little affinity with non-polar mineral oil and is almost not corroded by fuel oil and mechanical oil. among them, tpu products are characterized by the oil resistance of polyester series products. better

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 using high frequency or hot pressure, so it is widely used in inflatable products. generally speaking, the air tightness of polyester series products is better than that of polyether series.

10. biomedical performance

tpu film has excellent biocompatibility, non-toxic, non-allergic, no local irritation, and non-pyrogenic, so it is widely used in medical, health and other related products as well as sports and protective equipment.
