Why adhesive TPU can be used for shoe?
TPU adhesive, full name is thermoplastic polyurethane adhesive, is widely used in the manufacture of shoe glue due to its unique physical and chemical properties. Here are some reasons why TPU adhesive is suitable for shoe glue:
1. Excellent bonding performance
TPU adhesive can bond a variety of materials, including common shoe materials such as PU leather, PVC leather, genuine leather, nylon cloth, etc., as well as sole materials such as PVC sole, PU midsole, rubber sole, TPR, EVA, etc. This wide range of bonding ability makes TPU adhesive an indispensable part of the shoemaking industry.
2. Wear resistance and durability
TPU material itself has excellent wear resistance and durability, which makes the application of TPU adhesive in shoe glue can improve the overall durability of shoes. TPU has excellent wear resistance and abrasion resistance, good tensile strength and tear strength, which are very important for footwear products, especially in footwear products such as sports shoes and casual shoes that require high strength and wear resistance.
3. Good chemical and weather resistance
TPU adhesive has good chemical and weather resistance, which means it can maintain stable performance under different environmental conditions. This is an important advantage for footwear products, as shoes are often exposed to various climates and chemical environments.
4. Low temperature flexibility and high tensile strength
TPU adhesive can still maintain the physical and chemical properties of the material at low temperatures, which makes it suitable for footwear products in various climates. In addition, TPU adhesive has high tensile strength and high elongation, which are essential to ensure the safety and comfort of footwear products during use.
5. Good processing performance
TPU adhesive has good processing performance, is easy to mix with other resins, and can be processed after solvent dissolution. This allows manufacturers to flexibly adjust the formula to meet different production needs and quality standards.
6. Environmental protection characteristics
TPU is a mature environmentally friendly material with good recyclability. This meets the demand of modern consumers for environmentally friendly products and also helps shoemaking companies meet relevant environmental regulations and standards
