TPU thin film ten aspects of characteristics by Rainbow TPU

Date:Sep 19, 2019

TPU film is based on TPU particle material, through rolling, flow, blowing film, coating and other special processes made of film.Thickness 0.01 to 3mm.

TPU (Thermoplastic polyurethanes), thermal plasticity TPU elastomer, by including NCO functionality, MDI and OH functionality, POLYOL, 1.4 BG, made by mixing and extruding, with good elasticity, good physical properties, and a variety of mechanical strength is very good, therefore, widely used in injection, extruding, rolling and dissolved into solution such as resin processing way, is the plastic processing industry often use plastic material, made its products cover the range of industrial applications and civil necessities.

TPU is welcomed by people because of its superior performance and environmental protection. Currently, TPU can be used as a substitute for PVC.The characteristics of TPU film are mainly reflected in the following ten aspects:

1. The hardness

The higher the hardness level of TPU film, the higher the puncture resistance and wear resistance.Low hardness, the product shows a very smooth texture and very soft feel.

2. Wear resistance

The wear resistance of TPU films is superior to that of many other common polymers.More than five times the natural rubber wear-resistant, wear-resistant products is one of the first selection of materials

3. Tensile properties

TPU film tensile strength up to 70MPa, break elongation up to 800%, one of the most admirable properties is its tensile ability.

4. The weather

The weather aging resistance of TPU film is better than that of natural rubber and other synthetic rubber.

5. Low temperature flexibility

TPU film has excellent softness at low temperature.Most membranes remain flexible even when exposed to temperatures as low as -30 degrees Celsius, making them ideal for harsh environments.

6. Good temperature resistance

TPU film temperature resistance up to 130 degrees Celsius, polyether series temperature resistance up to 90 degrees Celsius.

7. Oil and chemical resistance

TPU is a kind of high-polarity polymer material, which has little affinity with non-polar mineral oil and almost no erosion in fuel oil and machine oil

8. Biomedical properties

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 protection equipment

9. Environmentally friendly and degradable

TPU film will not produce air pollution when burning, and can be biodegraded in soil within 3-5 years. Polyester series will be completely hydrolyzed after being immersed in water at 50 ° c for half a year or 70 ° c for 3 weeks or 100 ° c for 3-4 days.

10. Wide application

TPU films can be made using vacuum or thermal processing while still retaining their flexibility and performance.The material can also be welded into irregular shapes.TPU film has been widely used in: shoes, clothing, inflatable toys, water and underwater sports equipment, medical equipment, fitness equipment, car seat materials, umbrellas, suitcases, bags and so on
