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

Tin base stabilizer

توشته شده توسط Fatemeh Rajabi

Tin Base Stabilizer PVC compounds usually have limited heat resistance. To bolster this resistance, tin base stabilizers are employed to counteract PVC degradation caused by heat during processing. Among the most effective stabilizers for enhancing PVC’s heat resistance are those based on tin. Tin-based compounds can be classified into two categories :Mercaptides and Carboxylates . Mercaptide-type stabilizers of tin are suitable for rigid PVC packaging with a PVC coating:  These include MTM (Methyl Tin Mercaptide)

Epoxy soybean oil

توشته شده توسط Fatemeh Rajabi

Epoxy soybean oil ( Payaflex ESO 60 )  is a yellow liquid, and the less yellowish it is, the higher the quality of the oil. Soybean oil is converted to epoxy through oxidation. The higher the conversion of double bonds to epoxy, the higher the compatibility of this oil with PVC, and the iodine value of the oil decreases while the oxirene number increases. The suitable iodine value for epoxy soybean oil for 95% compatibility with

Processing Aids in PVC production

توشته شده توسط Fatemeh Rajabi

Introduction In PVC production, one of the biggest challenges is shaping the material due to the high viscosity of the molten PVC. To overcome this challenge, Processing Aids are used. These acrylic-based additives improve melt flow, enhance the surface quality of the final product, and reduce energy consumption during the melting and shaping process. What Are Processing Aids? Processing Aids are acrylic-based additives that are incorporated into PVC formulations to improve the flow of the

Barium-Cadmium-Zinc Stabilizer

توشته شده توسط Fatemeh Rajabi

Ba-Cd-Zn stabilizers are a combination of salts derived from three key metals, each playing a specific role in preventing PVC degradation: Barium: Enhances thermal stability and prevents the structural degradation of PVC at high temperatures. Zinc: Ensures better initial color and prevents discoloration during the early stages of production. Cadmium: Improves initial color and provides light stability, preventing discoloration when exposed to light. The Key Role of Cadmium: In some applications, a Barium-Zinc combination (without

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
