General description

Pentaerythritol tetrakis(3,5-di-tert-butyl-4-hydroxyhydrocinnamate) (PT) is a sterically hindered phenolic antioxidant and a heat stabilizer mainly used to enhance the oxidative resistance and protection against the toxicity of solvents. It has a glass transition temperature of 50 0C and can be annealed at room temperature.

Application

PT can be used as an additive to protect biaxially-oriented propylene (BOPP) capacitor film from thermal oxidation on UV exposure. It can also be used as a standard material to study the gas-cluster ion sputtering (GCIS) using X-ray photoelectron microscopy (XPS) and Atomic force microscopy (AFM).
