Production Technology Of Composite Stabilizer

Composite stabilizer is still as the main stabilizers in various metal salts, use of synergies and added to its effect, coupled with a variety of secondary stabilizers, further improve the stability of the metal salt system effect. In the liquid component of the composite stabilizer design, general control of metal salts concentration of 2%~15% (metal ion), phosphite 10%~50% (mass fraction, the same below), antioxidant, 1%~4%, 1%~10% of lubricants, solvents, 20%~40%. Liquid industrial compound stabilizers to produce mainly primary stabilizer of preparation, stabilizer and stability enhancers, additive mixing, bleaching and filtering processes. Solid stabilizer in PVC resins and processing modifiers such as chlorinated polyvinyl chloride (CPE) and ethylene-vinyl acetate copolymer (EVA), as the carrier, controlling the salt concentration 10%~50% (metal ion), lubricant content 5%~15%, mass fraction of secondary stabilizers 5%~10%. Solid industrial compound stabilizers to produce mainly primary stabilizer preparation stability enhancers, additives, stabilizers and mixing, granulating process.
