The Impact of Volatility on PVC Granules

توشته شده توسط Fatemeh Rajabi

During the production process of PVC granules, one of the major challenges is bubble formation, which negatively affects the final product’s quality. At high temperatures, PVC undergoes dehydrochlorination, resulting in the release of hydrogen chloride gas (HCl). If this gas is not promptly removed from the process, it can become trapped within the granules, leading to bubble formation. In addition to HCl, other by-products from PVC decomposition, such as plasticizer evaporation, may also contribute to

Synthetic Polyethylene Wax

توشته شده توسط Fatemeh Rajabi

Polyethylene Wax: Polyethylene wax is a byproduct of high molecular weight polyethylene or HDPE. To produce this wax, HDPE is used as the raw material with a molecular weight typically ranging from 2000 to 4000. Initially, short chains are separated from HDPE through various processes such as chemical breakdown. Subsequently, these shortened chains are transferred to a suitable reactor for purification. The reactor, using heat and a solvent, separates impurities, resulting in polyethylene wax with

Alternative plasticizers for DOP

توشته شده توسط Fatemeh Rajabi

:Plasticizers Plasticizers are additives that enhance the flexibility and processability of plastics, preparing them for diverse applications. Among the extensive range of plasticizers, Di-Octyl Phthalate (DOP) is commonly used as a typical plasticizer. :DOP Plasticizer One of the primary functions of the DOP substance in Polyvinyl Chloride (PVC) products is to establish flexibility and softness. Achieving this characteristic necessitates an appropriate level of usage (above 5 P.h.r). DOP, in contact with the polymer chains, creates
