Application
1. Acts Tris(nonylphenyl)phosphite as a high-efficiency antioxidant and heat stabilizer in polyolefin processing, effectively preventing thermal oxidative degradation of PE, PP and PVC during extrusion and molding.
2. Serves Antioxidant TNPP CAS 26523-78-4 as a secondary antioxidant in rubber production, improving aging resistance and mechanical property retention of natural and synthetic rubber products stably.
3. Functions as a stabilizer in lubricant and coating formulations, enhancing thermal stability and oxidation resistance of industrial oils and polymer coatings reliably.
Storage and Precautions
Store Tris(Nonylphenyl)Phosphite (TNPP, CAS 26523-78-4, pale yellow viscous liquid, density 0.98g/cm³, flash point 225℃, combustible) at 5–30℃ in sealed HDPE drums in a cool, dry, well-ventilated area. Isolate from strong oxidants, acids and high temperatures to avoid hydrolysis and oxidation. Wear nitrile gloves, safety goggles and splash shield; avoid skin/eye contact, vapor inhalation and ingestion to prevent mild irritation. Reseal tightly post-use; dispose of waste per local phosphite & polymer additive environmental regulations.
What are the benfits of taking Tris(nonylphenyl)phosphite / Antioxidant TNPP?
Tris(Nonylphenyl)Phosphite is an industrial polymer antioxidant and stabilizer, not for direct pure-form human contact or ingestion; undiluted contact may cause slight skin dryness, and accidental intake will lead to gastrointestinal discomfort.
In regulated applications, Antioxidant TNPP CAS 26523-78-4 features excellent thermal and oxidative stability, good compatibility with polymers and lubricants, and remarkable synergistic effects with primary antioxidants to extend product service life.
