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 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 ( 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
