For procurement managers, R&D scientists, and formulation chemists in the chemical industry, sourcing high-quality raw materials is critical for product success. Diisodecyl Pentaerythritol Diphosphite (CAS 26544-27-4) is a specialized phosphite ester antioxidant and stabilizer, increasingly sought after for its performance in polymers, lubricants, and adhesives. As a leading manufacturer and supplier, we aim to provide clarity on what makes this compound valuable and how to procure it effectively. This guide aims to help you buy with confidence.

Understanding Diisodecyl Pentaerythritol Diphosphite

Diisodecyl Pentaerythritol Diphosphite is a liquid additive characterized by its excellent hydrolytic stability, strong peroxide decomposing capability, and its synergistic effect when used with primary antioxidants. Its phenol-free nature makes it an environmentally friendlier option for a range of applications, including PVC, polyurethanes, resins, and lubricants.

Key Properties Buyers Should Consider:

  • Appearance: Typically a clear liquid, indicating purity. Any cloudiness or color deviation might suggest contamination or degradation.
  • Purity (Assay): Look for high assay percentages, generally above 98.5%. Higher purity ensures consistent performance and predictable formulation behavior. We prioritize high purity in our manufacturing.
  • Acid Value: A low acid value (e.g., <0.5 mg KOH/g) is indicative of a well-produced product with minimal acidic impurities.
  • Hydrolytic Stability: This is a critical performance parameter. Reliable products will maintain their integrity and efficacy under humid conditions.
  • Phenol-Free Status: For compliance and safety, ensure the product is genuinely phenol-free.

Applications Driving Demand

The demand for Diisodecyl Pentaerythritol Diphosphite stems from its effectiveness in:

  • Polymer Stabilization: Enhancing thermal resistance and color stability in PVC, PU, and other polymers.
  • Lubricants: Acting as an antioxidant and corrosion inhibitor.
  • Adhesives and Coatings: Improving durability and longevity.

Sourcing Strategy: Choosing a Manufacturer and Supplier
