What is the difference between TPU material and silicone material?

FROM Rainbowtpu(www.rainbowtpu.com)

1. The TUP material is hard and the silicone material is soft;
2. The wear resistance, impact resistance and shock absorption of TPU materials are superior to those of silica gel materials;
3. The aging resistance of TUP materials is stronger than that of silica gel materials;
4, silica gel material is soft, poor elasticity, more sticky; TUP material is the opposite;
5, silica gel is easy to greasy, while the material is slightly poor, it is easy to get ash and ash; 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 data
TPU is used in shoe materials mainly due to its excellent elasticity and wear resistance. TPU-containing footwear products are much more comfortable to wear than ordinary footwear products. Therefore, they are widely used in high-end footwear products, especially some sports shoes and casual shoes.
TPU is increasingly popular for its superior performance and environmental protection concepts. At present, wherever PVC is used, TPU can be a substitute for PVC. TPU film can be used not only to bond with various fabrics, but also to produce clear and dimensionally stable products by vacuum thermoforming.
With the continuous improvement of domestic environmental awareness, the application of TPU has become more and more extensive. Among them, the areas with faster speed increase: upper lining, thermal underwear, transparent underwear, transparent shoulder strap, elastic band and medical breathable tape.
TPU adhesives are a type of polyurethane adhesive. The use of polyurethane adhesives in Europe and the United States has become quite common, especially in the use of footwear adhesives, almost exclusively using polyurethane adhesives. The use of TPU adhesive in China is obtained by dissolving TPU and then obtaining a polyurethane adhesive after processing. In the use of TPU adhesives, mainly in the four main regions of Guangdong, Fujian, Zhejiang and Shanghai.
Because TPU hose has softness, good tensile strength, impact strength and high temperature resistance, TPU hoses are widely used in China for gas transportation and transportation of aircraft, tanks, automobiles, motorcycles, machine tools and other mechanical equipment. hose. The main TPU hose manufacturing enterprises are concentrated in Guangdong, Zhejiang, Jiangsu, Shandong, Hebei and other places.
