Performance advantages of TPU film
TPU film has good tensile elasticity. During the traction and winding process, attention must be paid to maintaining the stability of the tension and reducing the traction as much as possible. Therefore, some equipment adopts tension closed-loop control to achieve constant tension of traction, ensure the stability of tension, and wind through gap winding.
Ten characteristics of TPU film.
difficulty
The higher the hardness level of the TPU film, the higher the puncture resistance and abrasion resistance of the product. The hardness is low, and the product presents a very soft texture and a very soft hand.
Abrasion resistance
The abrasion resistance of TPU film is better than many other common polymers. It is more than 5 times more wear-resistant than natural rubber and is one of the first-choice materials for wear-resistant products.
Ductility
The tensile strength of TPU film is as high as 70 MPa, and the elongation at break can be as high as 800%. One of the most commendable properties is its ability to stretch.
Weather capability
The weathering resistance of TPU film is better than natural rubber and other synthetic rubbers.
Low temperature flexibility
TPU film has excellent flexibility at low temperatures. Most films remain flexible even when exposed to temperatures as low as -30 degrees Celsius, which makes them ideal materials for harsh environments.
Good temperature resistance.
The temperature resistance of TPU film can reach 130, and the temperature resistance of polyether series can reach 90.
Oil and chemical resistance.
TPU is a high-polarity polymer material, which has almost no affinity with non-polar mineral oil, and is hardly corroded in fuel oil and engine oil. Among TPU products, polyester products have better oil resistance.
How to chooseTPU film to buy a suitable TPU film.
TPU film
1. Taste
The taste of TPU film is different from other plastics, it is not easy to cause irritating smell, and it will not release harmful gas. If you smell it carefully, you will smell the delicate fragrance of TPU film;
2. Combustion burns the TPU film, and the thick smoke is milky white smoke. If a small amount of black smoke from the exhaust pipe occurs, it indicates that the combustion is insufficient;
3. Decomposition It only takes a year or so to decompose the TPU film into the soil layer. After decomposition, it becomes water = radon gas and co2, which is not easy to cause harm to the soil layer.
Therefore, the TPU film is not easy to cause the destruction of the large geographical environment, and at the same time, it will not cause harm to the body. Everyone can feel at ease.
