Study of the effectiveness of magnesium-zinc stabilizer based on pentaerythritol in the roll-calender processing of polyvinyl chloride

Abstract

A comparative analysis of a magnesium-zinc stabilizer based on pentaerythritol and a standard calcium-zinc stabilizer based on stearic acid was carried out. The influence of the ratio of pentaerythritol magnesium (PenMg) to pentaerythritol zinc (PenZn) on the thermal and thermo-mechanical stability of polyvinyl chloride (PVC) is considered.
