Sinanox® 245 Usage

Antioxidant 245 is mainly used in HIPS, ABS, MBS and other styrene polymers and POM, PA and other engineering thermoplastic resins for processing and long-term heat stabilization, but also in the PVC polymerization process as an effective chain terminator.

Antioxidant 245 is an asymmetric hindered phenolic antioxidant with good compatibility, low volatility, good thermal stability and high antioxidant efficiency. The antioxidant effect is significantly higher than that of general-purpose antioxidants of the same type, and when used with phosphate ester antioxidants and thioester antioxidants, it produces excellent synergistic effects. Suitable for AS resins, ABS resins, MBS resins, polyformaldehyde, polyamides, polyurethane, PVC, styrene butadiene latex, hydroxy butadiene rubber, high impact polystyrene. Used as a chain terminator for PVC polymerisation, does not affect the polymerisation reaction and can be added to the monomer prior to polymerisation. The general dosage is 0.1-0.5%.

Suitable for: high-impact polystyrene, ABS resin, AS resin, MBS resin, PVC, polyacetal, polyamide, polyurethane, etc. The dosage is 0.03%~1%. This product has a significant synergistic effect when used with thioether antioxidants or phosphorus containing antioxidants.
