comprehensive analysis of TPU film
Thermoplastic polyurethane (TPU) not only has the properties of high strength, high wear resistance and other properties of the crosslinked polyurethane, but also has the thermal plastic properties of linear polymer materials, so that the application of the thermoplastic polyurethane is extended to the plastic field. Especially in recent decades, TPU has become one of the fast developing polymer materials.
TPU thin film is an important application form of TPU materials. In recent years, it has been widely used with the development and progress of high technology. However, because of its difficulty in processing and unstable products, no manufacturers in mainland China have been able to make mass production.
Brief introduction of TPU film
TPU films have excellent properties such as high strength, high toughness, high toughness, abrasion resistance, oil resistance, cold resistance, aging, non-toxic and degradable, which are incomparable with other plastics and rubber. It also has excellent properties such as waterproof, wind proof, wind proof, cold proof, anti cold, antibacterial and anti ultraviolet. It can be used in many industrial and civil fields. It is a green film and an ideal substitute for PVC film.
The above table shows that the comprehensive properties of functional TPU films are obviously better than those of general plastics and rubber. TPU films are pided into two categories: polyester and polyether. Polyester products have good heat resistance and chemical resistance. They are widely used in the use of replacing PVC products. Polyether has better resistance to low temperature, water resistance and mildew resistance, and is widely used in products related to water.
According to the online understanding of coating, TPU film can be pided into blown film series and tape casting series because of their different manufacturing processes.
TPU film market
The production of TPU materials is mainly distributed in the United States, Western Europe and Japan, and China's Taiwan area also has a certain proportion. Because of the very unstable characteristics of TPU film products in the process of production, the development and testing need advanced technology and equipment; on the other hand, because of the competition of other materials, the economic factors also make the production of TPU film must be more efficient, and can produce high quality TPU thin film to reduce cost. It also requires wider variety of TPU film, thinner and thicker thickness, and better technology to enhance its physical properties, resulting in higher added value. The above two aspects have become the bottleneck restricting the development of TPU manufacturers in China.
