TPU film

What are the advantages of TPU film? TPU is increasingly popular for its superior performance and environmentally friendly concepts. At present, wherever PVC is used, TPU can be a substitute for PVC. TPU film can be used not only to bond with various fabrics, but also to produce a clear and dimensionally stable product by vacuum thermoforming. With the continuous improvement of domestic environmental awareness, the application of TPU has become more and more extensive. Among them, the areas with faster speed increase: upper lining, thermal underwear, transparent underwear, transparent shoulder strap, elastic band and medical breathable tape. In addition, there are a large number of applications in the field of apparel fabrics. The fabrics after TPU film bonding have the effect of waterproof, warm, moisture and breathability, which is very suitable for sportswear.

TPU advantages are organized as follows

1, wear resistance

More than five times more wear-resistant than natural rubber, it is one of the preferred materials for wear-resistant products.

2, tensile properties

The tensile strength is up to 70 MPa and the elongation at break can be as high as 800%.

3, tear performance

TPU film has high tear resistance and tear strength is better than common rubber and plastic

4, tortuous performance

TPU products can maintain excellent tortuosity under different environments, and are one of the best choices for polymer materials.

5, hydrolysis resistance

TPU has good water resistance under turbidity and does not undergo significant hydrolysis in 1-2 years.

The polyester series is soaked in water at 50 degrees Celsius for half a year or 70 degrees Celsius for 3 weeks or 100 degrees Celsius for 3-4 days. It is completely hydrolyzed, which is one of the reasons why TPU film is suitable for environmentally friendly materials.

6, anti-high temperature and anti-oxidation

TPU has good oxidation resistance. The temperature resistance of general polyester series can reach 130 degrees Celsius, and the temperature of polyether series can reach 90 degrees Celsius.

7, oil and chemical 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 mechanical oil. Among them, the oil resistance of polyester series products in tpu products Better

8, low temperature performance

TPU film has very good low temperature resistance, usually reach -40 degrees Celsius, which is a good substitute for PVC.

9, air tightness

TPU is very easy to weld with high frequency or hot pressing, so it is widely used in inflatable products. In general, polyester series products are more airtight than polyether series.

10. Biomedical performance

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 and protective equipment.

Combine the above information to summarize the advantages of TPU

TPU (Thermoplastic polyurethanes), thermoplastic TPU elastomer, is made by MDI containing NCO functional group and POLYOL and 1.4BG containing OH functional group. It is made by kneading and mixing. It has good elasticity, good physical properties and various mechanical strengths. They are very good. Therefore, they are widely used in injection, extrusion, calendering and dissolving into solution type resins. They are plastic materials commonly used by plastics manufacturers. The products are made up of industrial applications and civilian necessities.

In recent years, due to the continuous development of new products, the use of thermoplastic PU elastomers is continuously increasing, creating a new opportunity for the plastics industry to create low-cost, high value-added industries.

TPU (thermoplastic polyurethane) is increasingly popular for its superior performance and environmentally friendly concepts. At present, wherever PVC is used, TPU can be a substitute for PVC. But the advantages of TPU, PVC is far behind.

TPU not only has excellent high tension, high tensile strength, toughness and aging resistance, but also is a mature environmentally friendly material. At present, TPU has been widely used in: shoe materials, garments, inflatable toys, sports equipment for water and underwater, medical equipment, fitness equipment, car seat materials, umbrellas, luggage, leather bags and so on.

The TPU film is formed on the basis of TPU pellets by calendering, casting, film blowing, coating, and the like. At present, it is widely used in sports shoes: trademark decoration on the sole and upper, airbags, air cushions, oil bags, etc.

There are two trends in the application of TPU film on sports shoes: one is the popular style blown by women's sandals, that is, the high transparent TPU film is directly cut, or screen printing is colored, or the cloth is folded into a clip. Mesh, etc., high-frequency forming and bonding on the upper, functional and decorative effects. The second is to use waterproof and moisture-permeable TPU film and shoe cloth to use together to achieve waterproof and moisture-permeable effect.
