Elastic webbing, as a clothing accessory, is especially suitable for underwear, trousers, baby clothes, sweaters, sportswear, rhyme clothes, wedding dresses, T-shirts, hats, busts, masks and other clothing products.
1. Wear resistance
When the material is often subjected to mechanical actions such as friction, scraping, and grinding of elastic bands during use, the surface will gradually wear out, so the choice of abrasion resistance of the webbing material is very important. TPU plastic material has excellent wear resistance, which is more than five times that of natural rubber, and is one of the first choice 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 100%.
3. Tear performance
The elastic body is damaged due to the expansion of the crack during application, which is called tearing. The strength of the tearing headlight belt is the ability of the material to resist tearing; generally speaking, TPU has a high tear resistance, and the tear strength is the same as Some commonly used rubber-plastic comparisons are excellent.Elastic webbing
4. Inflection performance
Many plastic materials are prone to fracture under repeated cyclical stress, and TPU products can maintain excellent flexural resistance in different environments, making it one of the best choices among polymer materials.
5. Hydrolysis resistance
TPU has good water resistance under turbidity, and will not undergo obvious hydrolysis within 1 to 2 years, especially the polyether series is better. Polyester series will be completely decomposed when soaked in water at 50°C for half a year or soaked in 70°C for 3 weeks or soaked in 100°C for 3 to 4 days. This is one of the reasons why TPU is suitable as an environmentally friendly material. It is recommended to use polyether series.Elastic webbing
6. High temperature resistance and oxidation resistance
General plastic raw materials are easy to oxidize in an environment above 70°C for a long time, and TPU has good oxidation resistance; generally speaking, the temperature resistance of TPU can reach 120°C.
