PVC internal lubricants are characterized by their strong compatibility with PVC polymers. By reducing cohesion between polymer molecules within the PVC matrix, internal lubricants effectively lower friction heat generation, promoting improved melt fluidity. This results in smoother processing of PVC materials.

PVC external lubricants limited compatibility with polymers, which allows them to migrate from the melt to the exterior. This migration forms a lubricating thin layer at the interface between the plastic melt and metal, effectively reducing friction. External lubricants play a crucial role in minimizing friction and improving the overall processing of PVC.

Lead Compound Stabilizer is comprises lead compounds, lubricants, antioxidants, and hydrotalcite as its primary constituents. serves a vital role in preventing PVC degradation, enhancing its heat and light stability.

Ca Zn Stabilizer,made by calcium salt,zinc salt,lubricants,antioxidant hydrotalcite as the main ingredients.

Tin Stabilizer features various tin-based compounds, combined with lubricants, antioxidants, and essential additives.The key role of Tin stabilizer is to shield PVC from degradation and enhance its heat and light stability.

Stearoylbenzoylmethane (SBM), also known as 1-phenyl-1,3-eicosanedione, with molecular formula C26H42O2, is an organic compound. Stearoylbenzoylmethane is a light white powder with no special odour, soluble in solvents such as toluene, acetone, trichloromethane and ethyl acetate, insoluble in water and hexane.

DBM is a β-diketone product, as a new auxiliary heat stabiliser for PVC, used with calcium/zinc, it is white or light yellow crystalline powder, easily soluble in ether, chloroform, xylene, toluene and aqueous sodium hydroxide solution, slightly soluble in ethanol, slightly soluble in water.

Hydrotalcite is an inorganic compound and a good acid absorber, which can effectively inhibit zinc combustion during processing. It is suitable for the addition of Ba / Zn system and Ca / Zn system formula. When the hard formula of Ca / Zn system is applied, its unique effect is more obvious, and it still has good thermal stability at high temperature of 400 ℃.
