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 a layered double hydroxide, and layered compounds refer to a class of compounds with a layered structure, interlayer ions, and exchangeability. Due to its unique layered structure and excellent physical and chemical properties, it has efficient acid absorption performance and good thermal stability,when combined with calcium zinc additives, it has a good doubling effect on thermal stability.
