Description

Bis(Bis(Nonylphenyl) Phosphite), Polypropylene, Glycols is a specialized polymeric antioxidant and stabilizer used in high-performance polymer systems. This compound matters for its ability to effectively inhibit oxidative degradation and thermal breakdown, thereby extending the service life of sensitive materials. It is primarily needed by manufacturers in the plastics, rubber, and specialty chemical industries seeking to enhance the durability and stability of their products under demanding conditions.

Application

• Polymer Stabilization: Acts as a highly effective antioxidant and processing stabilizer for polypropylene (PP), polyethylene (PE), and other polyolefins.
• Rubber Industry: Used to protect synthetic rubbers and elastomers from heat and oxygen-induced aging during processing and in final applications.
• Adhesives & Sealants: Enhances the shelf-life and thermal stability of hot-melt adhesives and various sealant formulations.
• Lubricant & Grease Additive: Serves as an antioxidant additive in synthetic lubricants and industrial greases to prevent viscosity increase and sludge formation.
• Coating Resins: Provides stabilization for alkyd resins and other coating systems susceptible to oxidative cross-linking and yellowing.
• Masterbatch Production: A key component in antioxidant and stabilizer concentrate masterbatches for simplified compounding.

Quality Control

Our production of Bis(Bis(Nonylphenyl) Phosphite), Polypropylene, Glycols adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing to ensure consistent performance, including assessment of active phosphite content, acid value, and color. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and easily oxidized; therefore, containers must be kept tightly sealed after opening to minimize exposure to air and moisture. For long-term storage, consider using an inert gas blanket.
