High-Performance Phosphorus-Containing Antioxidant is primarily used as a synergistic antioxidant for various synthetic resins including polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), ABS resin, and polyesters. It demonstrates exceptional effectiveness in preventing oxidation and improving color stability. 

The product itself exhibits high thermal stability, weather resistance, and hydrolytic stability, ensuring excellent processing performance.

Ideal for polymer materials requiring high-temperature processing, its trivalent organophosphorus structure delivers superior and highly efficient antioxidant performance. 

The product offers outstanding oxidation resistance, effectively inhibits "zinc burning," and provides good lubricating properties.

Structurally free of alkylphenols, this product is safe, non-toxic, and complies with the latest market regulations and development trends. Certified by SGS, it meets the quality requirements of EU RoHS and WEEE directives. Suitable for food packaging materials (TITLE 21 CFR.178.2010).

Primary Applications: ABS, PS, HIPS, NBR, SB, PP, PE.  

Lubrication Mechanism in PVC Processing During high-temperature processing of PVC plastics, a small portion of the lubricant intercalates between PVC molecular chains. This intercalation differs fundamentally from the physical dissolution of plasticizers in PVC: it involves no intermolecular forces, only weak adsorption interactions. Consequently, it reduces friction between PVC melt molecules and effectively lowers the melt viscosity.

The intercalation capacity of lubricants depends on their molecular structure and increases proportionally with temperature (enhancing intercalation at higher temperatures and reducing it at lower temperatures).

The majority of lubricant molecules migrate to the surface of the PVC melt, forming a lubricating film at the interface with processing machinery. This film substantially reduces friction between the PVC melt and equipment surfaces.

Classification by Function:

1. Internal Lubricants: Reduce PVC melt viscosity.

2. External Lubricants: Minimize friction between PVC melt and machinery surfaces.

3. Balanced Lubricants: Achieve both viscosity reduction and friction minimization.

Processing Characteristics:

- Internal lubricants require the shortest plastification time.

- External lubricants demand the longest plastification time.

Through these mechanisms, lubricants enhance PVC melt fluidity, facilitate release from machinery surfaces, and ultimately enable effective molding and processing.
