    When PVC is heated to a temperature of 170-180 degrees C, chlorine and hydrogen atoms in the molecule being released and the release of HCl is inevitable. As the decay process takes place, PVC molecular structure becomes unstable so as to accelerate the process of removing HCl release and destroy the molecular structure of PVC. Because PVC should be heated to soften during extrusion / molded preventing the escape of HCl is necessary due to temperature, otherwise will result in PVC structure was destroyed. Stabilizer works to prevent the escape of HCl from PVC original.
    Therefore, use of stabilizers (metal compounds) is necessary to prevent the destructive chain reaction. It can also be added to PVC resistant to light, weather, heat aging. Stabilizers that affect the physical properties as well as the cost of production materials. It has always been provided in the form of restricted application - special mixtures in which the main components are metal soaps (metal shoaps), metal salts (metal salts) and organometallic compounds species.The selection of thermal stability depends on several factors including the technical requirements of PVC products, regulatory requirements to be complied with and the cost of removal.

    The main metals in stabilizer is lead (Pb), barium (Ba), calcium (Ca), and tin (Sn). They are classified into stable Pb, Ba-Zn stabilizer, Ca-Zn stabilizers, and stabilizer Sn. Ba-Zn stabilizers and Ca-Zn is used as metal soaps such as stearates, while Sn stabilizers are used as organic tin (tin dialkyl compounds). In addition to the metal soap, Pb stabilizers used as sulfate (sulphate) basic, basic carbonates, or phosphates (phosphate) Basic.
