High-performance phosphite antioxidant offering excellent hydrolytic stability and low volatility.
Effective in suppressing thermal oxidation during high-temperature polymer processing (e.g., extrusion, injection molding).
Compatible with a broad range of polymers including polyolefins, engineering plastics, and elastomers.
Non-staining and low color formation—ideal for applications requiring high optical clarity and color fidelity.
Synergistic with hindered phenolic antioxidants (e.g., Irganox 1010), enhancing overall oxidative stability.
Polypropylene (PP) fibers and nonwovens for medical and hygiene products.
Polyethylene (PE) films used in food packaging and agricultural mulch films.
Automotive interior components made from thermoplastic olefin (TPO) blends.
Blends of polybutylene terephthalate (PBT) and polyethylene terephthalate (PET) for electrical connectors.
