1. The TUP material is harder and the silicone material is softer;
2. The wear resistance, impact resistance and shock absorption of TPU materials are better than those of silicone materials;
3. The aging resistance of TUP materials is stronger than that of silica gel materials;
4. Silicone material is softer, less elastic, and more sticky; the opposite is true for TUP material;
5. Silica gel is easy to be greasy, and at the same time, the material with poor material is easy to stain and enter the dust; TPU material has outstanding cold resistance, oil resistance, water resistance, and mold resistance;
6. TUP materials are more prone to yellowing than silica gel materials.
Extended information
TPU is used in shoe materials mainly due to its excellent elasticity and wear resistance. TPU-containing footwear products are much more comfortable than ordinary footwear products in terms of wearing comfort. Therefore, they are more widely used in high-end footwear products, especially some sports shoes and casual shoes.
TPU is increasingly popular with people because of its superior performance and environmental protection concept. At present, wherever PVC is used, TPU can become a substitute for PVC. TPU film can not only be laminated with various fabrics, but also can be vacuum thermoformed to produce products with clear contours and stable dimensions.
With the continuous improvement of domestic environmental protection awareness, the application of TPU has become more and more extensive. Among the areas with a relatively fast increase: shoe upper linings, thermal underwear, transparent underwear, transparent shoulder straps, elastic bands and medical breathable tapes.
TPU adhesive is a kind of polyurethane adhesive. The use of polyurethane adhesives in Europe and the United States has been quite common, especially in the use of shoe adhesives, almost use polyurethane adhesives. The use of TPU adhesives in my country is to obtain polyurethane adhesives after TPU is dissolved and processed. In the use of TPU adhesives, the main areas are Guangdong, Fujian, Zhejiang, and Shanghai.
Because TPU hose has softness, good tensile strength, impact strength, high and low temperature resistance, TPU hose is widely used in China for air and oil transportation of aircraft, tanks, automobiles, motorcycles, machine tools and other mechanical equipment. hose. The main TPU hose manufacturers are concentrated in Guangdong, Zhejiang, Jiangsu, Shandong, Hebei and other places.
