What is tpu material and what are the characteristics of tpu
Today the editor will share with you what is TPU material. Friends who like to buy mobile phone cases should know what TPU is. In fact, this material is often used as bed sheets, shower curtains, tablecloths, aprons and other home textiles. TPU can be used not only for home textiles, but also in medicine, national defense, industry and other fields. Let’s follow the editor to learn more about it in detail.
What is TPU material?
TPU is thermoplastic polyurethane elastomer rubber. TPU is a polymer polymerized by chemical reactions of diphenylmethane diisocyanate (MDI), toluene diisocyanate (TDI), biomacromolecule polyols, and chain extenders. It is a plastic material that can continuously soften or change at a specific temperature, but it can maintain its shape at normal temperatures and play a role of support and protection. It is widely used in shoe midsoles.
What are the characteristics of TPU?
1. Wide strength coverage: By changing the formulation of each chemical reaction component of TPU, it can be obtained Products with different strengths, and as the strength increases, the product still maintains stable ductility.
2. High mechanical strength: TPU handicrafts have outstanding load-bearing capacity, impact resistance and shock-absorbing properties.
3. Good production and processing characteristics: TPU can be produced and processed using ordinary thermoplastic material production and processing methods, such as injection, extrusion, calendering, etc. , TPU is produced and processed together with some polymers to obtain polymer cemented carbide with complementary properties.
4. Remarkable cold resistance: TPU has a relatively low glass state change temperature and remains stable at a subzero temperature of 35 degrees. ductility, flexibility and other physical properties.
5. Resistant to oil, moisture and mold.
6. High wear resistance: This can be seen by comparing the Taber wear coefficient of TPU with other materials.
7. Highly recyclable.
The above is what the editor has shared with you today. I hope it can be helpful to you.
