tpu is thermoplastic polyurethane elastomer rubber.
It is a kind of (AB) n-type block linear polymer, the biggest advantage of the TPU material is that it has good flexibility and can be destroyed at will. As a result, cell phone cases made of this material have good cushioning properties, can effectively prevent dropping, and are easy to install and remove. In addition, TPU material can use micro-matte technology to effectively prevent fingerprints and ensure the cleanliness of the phone.
TPU elastomer is a material between rubber and plastic. It is oil-, water- and mold-resistant.TPU products have excellent load-carrying capacity, impact resistance and shock absorption.TPU belongs to the category of plastics, and the product is made through the injection molding process. The plastic rice grains are heated and melted, and then they are injected into a plastic mold in a bucket to make the product.
Material Application:
1, Shoes
TPU is used in shoes mainly due to its excellent elasticity and abrasion resistance. TPU-containing footwear products are much more comfortable to wear than ordinary footwear products, therefore, it is more widely used in high-grade footwear products, especially some sports shoes and casual shoes.
2, film
TPU because of its superior performance and environmental protection concept is increasingly popular. Wherever the use of PVC, TPU can become a substitute for PVC. TPU film can not only be laminated with a variety of fabrics, but also vacuum thermoforming method to produce clear contours, dimensional stability of the product.
With the continuous improvement of domestic environmental protection awareness, the application of TPU is also more and more extensive. One of the faster increase in the field: shoe lining, thermal underwear, transparent underwear, transparent straps, elastic bands and medical use of breathable tape.
3, adhesive
TPU adhesive belongs to a polyurethane adhesive. The use of polyurethane adhesive in Europe and the United States has been quite common, especially in the use of footwear adhesive, almost using polyurethane adhesive.
The use of TPU adhesive in our country is to dissolve TPU, after processing to obtain polyurethane adhesive. In the use of TPU adhesive, mainly in Guangdong, Fujian, Zhejiang, Shanghai, four major regions.
4, hose
Because the TPU hose has a soft, good tensile strength, impact strength resistance to high and low temperatures, so the TPU hose in China is widely used as airplanes, tanks, automobiles, motorcycles, machine tools and other machinery and equipment such as gas and oil hoses. The main TPU hose manufacturing enterprises are concentrated in Guangdong, Zhejiang, Jiangsu, Shandong, Hebei and other places.
5, wire
TPU provides tear resistance, abrasion resistance and bending characteristics, high and low temperature resistance is the key to the performance of the cable. So in the Chinese market, higher cables such as control cables and power cables with TPU, used to protect the design of complex cable coating materials, the use is also increasingly widespread.
6, roller
Polyurethane elastomer with its high mechanical strength, abrasion resistance, excellent oil resistance, acid and alkali resistance, outstanding compression resistance and make it a large number of applications in the roller. Domestic rollers are mainly the following: industrial rollers, household rollers, sports equipment wheels, medical equipment wheels, toy wheels.
