Product introduction

季戊四醇四（3,5-二-叔4-羟基氢肉桂酸正丁酯）（PT）是一种空间位阻型酚类抗氧剂和热稳定剂，主要用于增强抗氧化性和抗溶剂毒性。它的玻璃化转变温度为500C，可在室温下退火。应用 PT可用作添加剂，以保护双轴定向丙烯（BOPP）电容器膜免受紫外线照射下的热氧化。它也可以作为标准材料，使用X射线光电子显微镜（XPS）和原子力显微镜（AFM）对气体簇离子溅射（GCIS）进行研究。 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 500C and can be annealed at room temperature.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).
