Poly(dipropyleneglycol) Phenyl Phosphite (CAS 80584-86-7) Overview

Basic Chemical Properties

Manufacturer Specification Comparison

Key Applications & Functional Advantages

Primary Industrial Uses

• Polymer Stabilization: Acts as secondary antioxidant in polyolefins (PP/PE), PVC, and engineering plastics
• Lubricant Additives: Prevents thermal degradation in synthetic engine oils (0.1-0.5% loading)
• Rubber Processing: Enhances aging resistance in SBR and NBR compounds
• Adhesive Formulations: Improves color stability in hot-melt adhesives

Performance Benefits

• Superior hydrolysis resistance compared to traditional phosphites
• Low volatility at high processing temperatures (up to 300°C)
• Synergistic effect with phenolic antioxidants (1:2 ratio recommended)
• FDA-compliant for indirect food contact applications

Technical Usage Guidelines

Recommended Formulation Practices

1. Storage: Keep in sealed containers under nitrogen atmosphere
2. Pre-blending: Mix with carriers like silica (1:1 ratio) for better dispersion
3. Processing Temp: Optimize between 180-260°C for maximum efficiency
4. Compatibility: Avoid strong acids/bases and amine-containing systems

Safety Handling Requirements

• Wear chemical-resistant gloves (nitrile recommended)
• Use local exhaust ventilation during transfer operations
• First Aid: Flush eyes with water for 15 minutes if contacted
