TPU waterproof and breathable membrane: It is a major breakthrough in the application of new environmentally friendly materials for waterproof and breathable fabrics. It overcomes many defects of PVC and PU leather. It not only has most of the characteristics of rubber and ordinary plastics, but also has excellent comprehensive physical and chemical properties. Performance, so it is also called future material.
TPU film is a film made of TPU pellets through a special process. It inherits the excellent physical properties of TPU and has a wide range of applications. According to the needs of domestic customers for TPU, our company can make corresponding widths according to customer requirements. Adjustment. Specializing in imported TPU film, TPU waterproof breathable film (transparent, translucent, matte, milky white, skin color, black) TPU hot air tape (waterproof strip), hot melt adhesive film, TPU elastic belt.
TPU transparent film: use: shoe making, luggage, handbags, clothing, military, toys, thickness: 0.02-0.2MM Product advantages: high strength, high tear strength, high oil resistance, low compression deformation, high elasticity, high softness.
TPU waterproof breathable membrane: color: matte, milky white, skin color, black. Thickness: 0.02---0.2MM Uses: clothing, shoe material and fabric fit, silicone chest pad, underwear accessories. Advantages: high water pressure resistance, high moisture permeability, Good feel, good processing performance, washable and dry cleaning.
What's the point?
What are the advantages of TPU film? TPU is increasingly popular because of its superior performance and environmental protection concept. At present, wherever PVC is used, TPU can become a substitute for PVC. TPU film can not only be laminated with various fabrics, but also can produce products with clear contours and stable dimensions by vacuum thermoforming. With the continuous improvement of domestic environmental protection awareness, the application of TPU is becoming more and more extensive. Among them, the areas with faster growth rate: shoe upper lining, 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 compounding. The fabrics laminated with TPU film have the effect of waterproof, warm, breathable and breathable, which is very suitable for sports clothing.
Advantages of TPU
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 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 the tear strength is better than that of commonly used rubber and plastics
4, tortuous performance
TPU products can maintain excellent bending resistance in different environments, which is one of the best choices in polymer materials
5. Hydrolysis resistance
TPU has good water resistance under turbidity, and will not undergo significant hydrolysis for 1-2 years
The polyester series will be completely hydrolyzed if soaked in water at 50 degrees Celsius for half a year or at 70 degrees Celsius for 3 weeks or at 100 degrees Celsius for 3-4 days, which is one of the reasons why TPU films are suitable for environmental protection materials.
6. High temperature resistance and oxidation resistance
TPU has good oxidation resistance, the temperature resistance of general 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. Better
8. Low temperature performance
TPU film has very good low temperature resistance, usually can reach -40 degrees Celsius, is a good substitute for PVC
9. Air tightness
TPU is very easy to use high frequency or hot pressure to weld, 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 properties
TPU film has excellent biocompatibility, non-toxic, no allergic reaction, no local irritation, no pyrogen, so it is widely used in medical, health and other related products as well as sports and protective equipment
