Matte finish, dull sand TPU, also known as thermoplastic polyurethane. The thermoplastic TPU elastomer is made by mixing and extruding MDI containing NCO functional groups with POLYOL containing OH functional groups and 1.4BG. What are the characteristics of TPU?

1. Wear Resistance. As materials are frequently subjected to mechanical actions such as friction, abrasion, and grinding during use, their surfaces gradually wear down. Therefore, the choice of materials with low wear is crucial. Matte finish sandblasted TPU boasts excellent wear resistance, which is more than five times that of natural rubber, making it one of the materials of choice for wear-resistant products.

2. Tensile Performance. The tensile strength reaches up to 70MPa, with a breaking elongation as high as 1000%.

3. Tearing Strength. Tearing refers to the destruction of an elastomer due to the expansion of a crack during application. Tearing strength is the ability of a material to resist tearing. Generally speaking, TPU has a high resistance to tearing, and its tearing strength is very excellent when compared to some commonly used rubbers and plastics.

4. Flexural Performance. Many plastic materials tend to fracture under repetitive cyclic stresses. TPU products maintain excellent flexural properties in various environments, making them one of the better choices among high polymer materials.

5. Hydrolysis Resistance. TPU demonstrates good water resistance under turbid conditions, showing no significant hydrolysis within 1-2 years, with the polyether series being particularly superior. The polyester series will completely decompose when soaked in water at 50℃ for half a year, 70℃ for 3 weeks, or 100℃ for 3-4 days. This is one of the reasons why TPU is suitable as an environmentally friendly material. For products that need to be in frequent contact with water, it is recommended to use the polyether series.
