If you want to correctly select TPU plastic materials for seals, kaen Medical Devices equipment suppliers believe that you must first master some knowledge of TPU plastic materials.

　　First, the working status of TPU plastic materials:

　　TPU plastic material seals are generally used in mining, metallurgical industry, crude oil, chemical plants, power engineering, mechanical equipment, excavators, dump trucks, anti-fouling components and other industries. This kind of seal is under high temperature (100-125°C) and high pressure natural environment, and there is also a complicated pressure release process of increasing and releasing pressure during the working process.

　　Second, selection is very important for TPU plastic raw material suppliers

　　 Looking for suppliers of TPU plastic raw materials, it is best to find experienced and capable suppliers for long-term collaboration to better ensure the long-term stability of product quality. It is recommended that the project be initiated at the beginning, and high-quality suppliers should be maintained to avoid changing suppliers for no reason. Under different working conditions, the types of TPU plastic materials are also different. Since TPU has three major raw materials, namely isocyanate, chain extender, and polyether polyol, there are many differences in types, and their characteristics are also different, which is suitable for different working conditions. Therefore, you must fully communicate with the dealer's professional and technical personnel to let them understand your requirements. The focus of communication is on the performance parameters of TPU raw materials (1, compressive shrinkage deformation; 2, tensile strength; 3, friction coefficient index value; 4, raw material viscosity). The TPU raw materials used for good seals should be raw materials with high production and processing temperature, small permanent deformation (≤35%), low coefficient of friction (below 30mm3), and high viscosity.

　　 In addition, the proper selection of the Children underpads raw materials for seals, the production and processing technology of TPU is also very important, and the production process is an important guarantee to ensure that the raw materials are fully utilized to the good characteristics.
