Tpu is a polymer containing a carbamate group (-NHCOO-) in the molecular chain. It is a segmented copolymer with hard and soft joints. It has plasticity, mechanical strength and rubber elasticity. Due to this unique structure, tpu can be widely used in: shoes, waterproof films, flow films, extruded tubes, waterproof dissociation films, automobiles, flame retardant cables, etc.
Unique advantages of TPU materials
The mechanical properties of TPU are adjustable compared to other materials. Shore hardness between 30A and 80D, excellent wear resistance, tear strength, tensile strength, high elongation at break, bending resistance, oil stain resistance, aging resistance, weather resistance, high water resistance, high permeability, Resistant to hydrolysis, environmental pollution, good biocompatibility, non-toxic and non-polluting.
Comparison of table performance between tpu materials and other materials
So at present, TPU is the best substitute for PVC. This is not only the tensile strength is much better than PVC, but also the low temperature resistance is unmatched by PVC; in addition, the degradability, antibacterial and plasticizer-free performance is superior to PVC. For high-end products, TPU is a good alternative to PVC.
Tpu film has the advantages of high temperature resistance, low temperature, strong toughness and environmental protection. It is gradually replacing PVC and other materials from various fields, and its consumption in China is also growing wildly. With the strengthening of our environmental awareness and the step-by-step improvement of technology, the scope of application of TPU film continues to expand. At the beginning of the 21st century, that is, in the four years from 2010 to the next, the average annual growth rate is about 15% of the market.
TPU film has the advantages of low temperature resistance, high toughness, high strength, environmentally friendly decomposition, and "breathability". It is replacing PVC, EVA, artificial leather and other materials in various fields, and its consumption in China is also growing. With the increasing awareness of environmental protection in the whole society, and with the further development of technology, the scope of application of TPU continues to expand. The overall market growth rate from 2010 to 2014 averaged 15% per year.
TPU film characteristics
The tpu film is formed by melt extrusion of the tpu material. The film has the advantages of high temperature resistance, high toughness, high strength, environmental protection and easy decomposition, and "breathability". They are gradually replacing pvc, eva, artificial leather and other materials, especially in the field of diaphragms. For example, footwear is the most expensive for TPU film. For example, some sports shoes, external shoes, and outdoor shoes require a large amount of film.
Sports equipment is mainly concentrated in water assault boats, inflatable boats, kite water, mainly using polyether TPU film;
Waterproof tpu film for home spinning, first aid clothing, outdoor products, medical supplies (surgical clothing)
