All users of high-grade polyurethane seals, hoping to purchase a reliable material, in order to ensure the quality of the seal.
If the quality is not pass, will have disastrous consequences.
Therefore, everybody is to buy high quality products, at any cost.
I found out that our domestic do polyurethane seal customers, most of them are more trust import TPU.
but, I also found many times, at least, more than half of the company, spend high price, purchase the good good import TPU material, but because of lack of understanding of the processing of TPU, leads to production of the product quality is far from its original performance, very pity.
so, we should be how to correctly choose the seals with TPU material?
correct selection of seal with TPU material, the first thing to understand some of the TPU polyurethane seal related knowledge.
first, about TPU seal condition:
TPU polyurethane seal commonly used in mining, metallurgy, petroleum, chemical, electric power, machinery, excavators, dump truck, dust components, etc. Seals must bear the high temperature in these fields ( 00 - 25℃) And high pressure environment, and in the process of work and pressure, pressure relief pressure heavy and complicated process.
suppliers is very important. The key point is to find the right supplier, genuine, found out the experience and ability to suppliers long-term cooperation, to ensure product quality long-term stability. This relationship to the company's purse, it is recommended that the project was a beginning, for suppliers to protect the quality, always do not change the supplier.
under different working conditions, the types of TPU is different also. TPU with isocyanate, chain extender, polyols three different raw materials, varieties also has a lot of difference, the performance is also suitable for different conditions. So should make the technical communication with suppliers, let them understand your needs. Communicate with each other with the focus on TPU material performance index ( , press the compression permanent deformation resistance; 2, the tensile strength; 3, wear indicator; 4, material viscosity) 。 Good seal with TPU material should be higher processing temperature, compression permanent deformation ( ≤35%) , low abrasion index ( Below 30 mm3) , viscosity larger raw materials. Simply put, quality data are key to speak.
in addition, the correct selection of good seal with TPU material, TPU processing technology is also a key to processing technology is the key to ensure material to the best performance. If you do not understand, must consult our TPU experts. TPU material requirements, if any, please contact us further communication.
