1. Acts Antioxidant 1330 as a high-efficiency phenolic antioxidant in polyolefin processing, effectively inhibiting thermal-oxidative degradation of PP, PE and their blends during extrusion and injection molding.

2. Serves Antioxidant 1330 CAS 1709-70-2 as a long-term heat stabilizer in engineering plastics and elastomers, stably improving high-temperature aging resistance of films, pipes and automotive plastic parts.

3. Functions as a synergistic additive with phosphite antioxidants, reliably enhancing light stability and color fastness of polymer products in outdoor applications.

Store Antioxidant 1330 (CAS 1709-70-2, white crystalline powder, mp 120-127℃, density 1.04g/cm³, purity ≥98.5%, non-flammable) at 5–30℃ in sealed HDPE/fiber drums in a cool, dry, well-ventilated area, away from direct sunlight, strong oxidants and acids. Wear nitrile gloves, safety goggles and dust mask; avoid dust inhalation, skin/eye contact and ingestion to prevent mild irritation. Reseal tightly post-use; dispose of waste per local polymer additive & antioxidant environmental regulations.

Antioxidant 1330 CAS 1709-70-2 is an industrial phenolic antioxidant for polymers, not for direct pure-form human contact or ingestion; undiluted contact may cause slight skin dryness and mucosal irritation. In regulated applications, Antioxidant 1330 CAS 1709-70-2 features excellent high-temperature stability, low volatility and migration, good compatibility with all polyolefins, remarkable long-term anti-aging effects at low dosage, and compliance with food-contact material safety standards.
