1. Acts Antioxidant 245 as a high-efficiency thermal stabilizer in styrene polymers (HIPS, ABS, MBS) and POM, preventing thermo-oxidative degradation during processing and end-use reliably.

2. Serves Antioxidant 245 CAS 36443-68-2 as a chain terminator in PVC polymerization, regulating molecular weight distribution and improving melt flow & processing stability of PVC products effectively.

3. Functions as a synergistic stabilizer in polyurethanes, polyamides and thermoplastic polyesters, boosting long-term thermal stability when combined with auxiliary antioxidants/light stabilizers.

Store Antioxidant 245 (CAS 36443-68-2, white/off-white crystalline powder, odorless, low volatility, mp 76–79°C, purity ≥98%) at 10–25°C in sealed HDPE or amber glass containers in a cool, dry, well-ventilated area. Isolate from strong oxidants, acids, alkalis and moisture to avoid degradation and discoloration. 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 hindered phenol antioxidant & polymer additive environmental regulations.

Antioxidant 245 is a polymer additive and PVC polymerization chain terminator, not for direct pure-form human contact or ingestion; accidental intake may cause gastrointestinal discomfort, and long-term dust exposure may irritate the respiratory tract. In regulated use, Antioxidant 245 CAS 36443-68-2 has high thermal-oxidative stabilization efficiency, low volatility and excellent extraction resistance, shows good compatibility with most polymer systems, and delivers remarkable synergistic effects with auxiliary antioxidants/light stabilizers to extend product lifespan and maintain color stability.
