Materials Testing & Research

Preparative HPLC followed by GPC-MS to investigate the potential leachable compounds produced by the degradation of pentaerythritol tetrakis (3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate)

At a concentration of about 1000 ppm in a polymer matrix, this additive provides excellent processing and long term thermal stability for a wide variety of materials such as plastics, synthetic fibers, elastomers, adhesives, waxes, oils and fats, and several analytical methods exist for its identification and quantification.
