How does FT wax improve the processing performance of PVC
Posted by Ella Wang on May 29th, 2019
Let's see how Fischer tropsch wax suppliers improve the processing performance of polyvinyl chloride (PVC). PVC resin processing has the characteristics of poor fluidity, poor thermal stability, easy decomposition and so on. The products produced are brittle and have poor impact resistance. Therefore, it is necessary to add various auxiliary materials in the processing process to improve product performance. In the process of PVC resin, the choice of lubricant is very important. Fito's synthetic wax meets this requirement. This reduces the difficulty of formulation design and effectively improves the efficiency of granule resistance and processing AIDS.
Fischer tropsch wax suppliers have obvious synergistic effects with stabilizers for PVC processing, which can effectively extend the thermal stabilization time and increase the adjustment range of process temperature. The high melting point of fetor synthetic wax is particularly evident in the processing of C polyvinyl chloride resin. Since the narrow adjustment range of processing parameters of PVC resin increases the processing difficulty of products, the selection of high melting point fetor synthetic wax can effectively improve the post-processing lubrication of C PVC products, and improve the appearance and mechanical properties of products.
Fischer tropsch wax suppliers can effectively improve the precipitation of small and medium molecular impurities during product processing. When it comes to the precipitation of small impurities, many people believe that too much lubricant is the cause. Not really. Too much lubricant will definitely migrate to the surface of the product. In particular, PVC pipe production, impurities will adhere to the mouth mold and focus coke, so that the product surface luster.
Polyvinyl chloride processing surface impurity precipitation is more used stabilizer medium and small molecular substances precipitation, especially calcium and zinc stabilizer, after a period of time after the production of impurity precipitation phenomenon. Some are even more serious, the precipitated impurities even adhere to the sizing sleeve. If appropriate fetor synthetic wax is added to the formula to keep the internal and external lubrication balance, the surface precipitation of impurities can be effectively reduced.
