TPU film is a material containing -NH-COO- groups in the molecule. The long-chain glycol and isocyanate components constitute the soft segment, and the short-bonded diol and isocyanate components constitute the hard segment. Many characteristics of TPU depend on the long-chain two The type of alcohol, its hardness is adjusted by the ratio of hard segment, and the light aging property of TPU elastic band can be improved by adding light stabilizer
TPU is used in shoe materials mainly due to its excellent elasticity and abrasion resistance. TPU-containing footwear products are much more comfortable than ordinary footwear products. Therefore, they are more widely used in footwear products, especially some sports shoes and casual shoes.
TPU film also has this high water resistance, because the film with good air permeability is generally made of polyether TPU, so its hydrolysis resistance and antibacterial properties are particularly good, that is, because of its high strength and its Water pressure resistance is also particularly excellent.
TPU film not only has most of the characteristics of rubber and ordinary plastics, but also has a good comprehensive physical and chemical properties, so tpu film is also called the future material.
