Product Description

Antioxidant 24 is an organophosphite antioxidant that protects materials from oxidative degradation during processing and storage. It scavenges radicals and decomposes hydroperoxides, minimizing color change and polymer degradation. It works efficiently at low concentrations and synergistically with other antioxidants and stabilizers.

Applications

• Polyolefins (PE, PP)
• Engineering plastics (polycarbonate, polyamide)
• Elastomers, rubber, coatings, adhesives
• Styrenic polymers, PVC, and other thermoplastics
• Used in masterbatches and polymer formulations to improve processing stability and color retention

Storage & Handling

• Store in a cool, dry place (2–8 °C), preferably under an inert atmosphere
• Avoid exposure to heat, flames, and moisture
• Handle in a well‑ventilated area to prevent dust accumulation
• Keep containers tightly closed when not in use

Safety Information

• May cause skin and eye irritation
• Harmful if swallowed or inhaled in dust form
• Use personal protective equipment: gloves, goggles, and a lab coat
• Avoid ingestion and inhalation; do not eat or drink while handling
