Polyurethane PU is a new maromolecule material developed in Germany in the 1960s. It has the characteristics of rubber and plastic. Polyurethane equipment can with elastomer, fiber, synthetic leather, adhesives, sealants and other various forms are widely used in chemical industry, light industry, transportation, construction, textile, aerospace and mechanical and electrical, medical and health care and etc, which is closely related to the national economy and people's life. Therefore, PU pneumatic tube production line industry prospects are broad.
PU (polyurethane) tube has excellent wear resistance, high pressure resistance, vibration resistance, corrosion resistance, torsion resistance and other properties, and PU tube is light, easy to use, flexible, easy to install, size precision control of inside and outside diameter is high. The tube is widely used in compressed air pipe, pneumatic components, liquid delivery pipe, protective sleeve and so on.
Why can polyurethane equipment has such a big market? Polyurethane material can be widely used because it has the best thermal insulation performance. Polyurethane is widely used in international building energy conservation because of its advantages in thermal insulation.
Since the 1960s, Germany has used the implementation of external wall insulation with polyurethane rigid foam, European and American countries 50% of the polyurethane rigid foam is used in the field of building insulation, in Japan, spraying polyurethane polyurethane rigid foam is widely used in high-rise apartment wall internal insulation, the proportion of more than 50%. But in China, the application proportion of polyurethane hard package in the field of building insulation is still less than 10%, and there is a huge space in the application field.
