Antioxidant 1010

CAS 6683-19-8

Antioxidant 1010 (pentaerythritol tetrakis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate), CAS 6683-19-8) is a high-molecular-weight hindered phenolic primary antioxidant. Its high molecular mass and low volatility give excellent extraction resistance and long-term thermal stability, making it the standard protection package for polyolefins, styrenics, engineering plastics, elastomers, adhesives and hot-melt systems. It is frequently combined with phosphite secondary antioxidants and hindered amine light stabilisers. Buyers compare assay, melting range, volatile matter, ash and solution clarity for sensitive film and fibre applications.
