Thermoplastic TPU

Thermoplastic TPU plastic raw materials excellent abrasion resistance, wear-resistant natural rubber more than five times, is one of the first choice of wear-resistant products materials!

Tensile strength up to 70MPa elongation at break can be as high as 1000%.

Thermoplastic TPU has a high resistance to tearing, tear strength and some commonly used rubber and plastic comparisons is very excellent.

Many plastic materials in the repetitive cyclic stress is prone to fracture, TPU products in different environments can maintain excellent flexural properties, one of the best choice for polymer materials.

Thermoplastic TPU in the turbid water resistance is good, 1 ~ 2 years will not occur significantly hydrolyzed, especially with the polyether series is better. Polymerase series in 50 ° C soaked in water for half a year or 70 C soaked 3 weeks or 100 ° C soaked 3 ~ 4 days, will be completely decomposed, which is TPU suitable for environmental protection as one of the reasons for the material, need to frequently contact with water products, it is recommended to use the polyether series.

Like plastic raw materials in the environment above 70 ° C for a long time is easy to oxidize, TPU antioxidant ability is good: generally speaking, TPU temperature resistance can reach 120 ° C.

TPU is a strong polar polymer materials, and non-polar mineral oil affinity is very small, in the fuel oil (such as kerosene, gasoline) and mechanical oils (such as hydraulic oil, oil, lubricants, etc.) in the almost non-erosion; which TPU products in the polycool series of products is better oil resistance: TPU film and sheet for the volume of the grease change is very small, the tensile strength is even higher than the original initial value; need to be careful! It should be noted that if there is a small amount of water in the mineral oil, it will have different degrees of negative impact on the physical properties of the film.

TPU has very good low-temperature resistance, usually up to -50C, can replace the general PVC due to low-temperature embrittlement and can not be applied in various fields, especially suitable for use in the cold zone related to the type of products.

TPU is very easy to use high-frequency or hot pressure to melt, so it is widely used in inflatable products.

Thermoplastic TPU has excellent biocompatibility, non-toxic, non-allergic, non-localized irritation, non-thermogenic, so it is widely used in medical, health and other related products, as well as sports, protective equipment.
