TPU film, thermoplastic TPU elastomer, is made by MDI containing NCO functional group and POLYOL, 1.4BG containing OH functional group. It is made by kneading and mixing. It has good elasticity, good physical properties and good mechanical strength. Therefore, it is widely used in injection, extrusion, calendering and dissolving into solution type resins. It is a plastic material often used by plastics processing industry. Its products cover the range of industrial applications and civilian necessities. TPU is superior because of its superiority. Performance and environmental concepts are more popular. At present, wherever PVC is used, TPU can be a substitute.
Characteristics of TPU film
. The higher the hardness grade of the TPU film, the higher the puncture resistance and the abrasion resistance. The hardness level is low, and the product exhibits a very supple texture and a very soft hand.
2, Wear resistance
The wear resistance of TPU films outweighs many other common polymers. More than five times more wear-resistant than natural rubber, it is one of the preferred materials for wear-resistant products.
The TPU film has a tensile strength of up to 70 MPa and an elongation at break of up to 800%. One of the most acclaimed properties is its stretchability.
4, Weather resistance
The weathering resistance of TPU films is superior to that of natural rubber and other synthetic rubbers.
5, Low temperature flexibility
The TPU film has excellent low temperature flexibility. Even when exposed to as low as -30 degrees Celsius, most films remain flexible, making them ideal for demanding environments.
6, Good temperature resistance
The temperature resistance of TPU film 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, and has low affinity with non-polar mineral oil. It is hardly eroded in fuel oil and mechanical oil. Among them, TPU products are resistant to oil in polyester series. Preferably.
8, Biomedical performance
TPU film has excellent biocompatibility, non-toxicity, 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.
9, Environmentally friendly degradability
TPU film does not produce air pollution when burned. It can be biodegraded in soil for 3-5 years. The polyester series will be completely hydrolyzed by immersing in 50 degrees Celsius water for half a year or 70 degrees Celsius for 3 weeks or 100 degrees Celsius for 3-4 days.
10. Wide applicability
TPU films can be vacuum or hot processed while still retaining their flexibility and performance. This material can also be welded into an irregular shape.
TPU film has been widely used in: shoe materials, ready-to-wear, inflatable toys, sports equipment for water and underwater, medical equipment, fitness equipment, car seat materials, umbrellas, luggage, leather bags, etc.
