With the development of society and the advancement of technology, the application of new materials has become more and more extensive. Since the beginning of the 1980s, polyurethane elastomers have changed from military to military and civilian, and after civilian-oriented, the variety of products has continuously increased. The scale of production is increasing, and the role played by various sectors of the national economy
Polyester TPU is the most important product in the global TPU film market in 2015, and its value as of 2024 will total a total of 212.8 US dollars. On the other hand, TPU is expected to show strong demand growth and revenue during the forecast period. Some will plan to expand the compound annual revenue growth rate to 7%
According to the 2018-2025 global and Chinese polyurethane sealant market status research and development prospect report released by China Industry Research Network, polyurethane sealant (polyurethanesealant) is a sealant mainly composed of polyurethane rubber and polyurethane prepolymer. This type of sealant has high tensile strength, excellent elasticity, wear resistance, oil resistance and cold resistance, but its water resistance, especially alkali resistance, is not good.
1. Good corrosion resistance; mainly used in medium acid and strong alkali occasions, such as: acid and alkali flow meters, pumps, valves in chemical industry, printing and dyeing machinery, corrosion-resistant sliding parts in the marine industry.
Polyurethane is a general term for high-molecular polymers containing imidic acid groups (-NH-CO-O) in the molecular chain, referred to as PU (Polyurethane). It is usually prepared by reacting polyisocyanate with compounds or polymers containing polyhydroxyl groups. The polyurethane film used as packaging material is a thermoplastic polyurethane elastomer (abbreviated as TPU).
