Pentaerythritol tetrakis(3,5-di-tert-butyl-4-hydroxyhydrocinnamate)
What is Pentaerythritol tetrakis(3,5-di-tert-butyl-4-hydroxyhydrocinnamate)?
Pentaerythritol tetrakis(3,5-di-tert-butyl-4-hydroxyhydrocinnamate) (CAS 6683-19-8) is a hindered phenolic primary antioxidant used to protect polymers, lubricants, and industrial formulations from oxidative degradation.
Where is Pentaerythritol tetrakis(3,5-di-tert-butyl-4-hydroxyhydrocinnamate) used?
- Plastics and polymer processing: stabilizes polyolefins, engineering thermoplastics, and elastomers against thermal oxidation during high-temperature extrusion and molding
- Lubricants: prevents viscosity breakdown and deposit formation in synthetic and mineral base oils under sustained operating conditions
- Adhesives and sealants: maintains bond integrity and prevents discoloration in heat-cured systems
- Coatings and packaging: protects film substrates
- It protects printed surfaces from oxidative yellowing throughout the product shelf life.
Good to know: It functions by scavenging free radicals generated by heat and oxygen exposure, extending the functional lifespan of finished materials during processing and long-term service.
