What is PU?
PU is a new type of organic polymer material, known as the "fifth largest plastic". Because of its excellent performance, it is widely used in many fields of the national economy. The product application fields involve light industry, industry, electronics, etc. At the same time, polyurethane is often used as a substitute for rubber products in harsh environments because of its resistance to a variety of acids, alkalis and organic solvents.
The application of PU:
PU can be used to make plastics, rubber, fibers, rigid and flexible foams, adhesives and coatings. It can be used in all areas of people's lives and has a wide range of applications. At the same time, hydraulic seals can also be made.
It is required that the leakage of hydraulic seals is extremely small, has a good sealing effect, and automatically increases its seal as the pressure of hydraulic oil increases. It is used as a series of Dongsheng hydraulic seals. Even in harsh working environments such as high pressure and high temperature, hydraulic seals There is no significant increase in the leakage of parts.
Product characteristics:
Temperature resistance is -20℃-120℃.
Polyurethane products are pollution-free, non-toxic and tasteless.
Long service life and cost reduction.
