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).

HPLC Analysis of Phenolic Antioxidants on Ascentis® Express C18 2.7 μm

Phenolic Antioxidants are added to polyers for controlling their degradation process. Irgafos 168, Irganox 1010, Ethanox 330, Irganox 1076, BHT, and Irgafos 168 are often used as antioxidants to prevent the degradation of polypropylene polymer formulations. This HPLC method is for the quantitation of an additive or mix of additives in a polymeric material.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
