MAGNESIUM SULFATE FOR SYNTHETIC RESIN HEAT STABILIZER

摘要

PURPOSE: Magnesium sulfate is provided, to improve the heat resistance of a synthetic resin as a heat stabilizer up to 100 % by treating it with EDTA compared with the untreated magnesium sulfate. CONSTITUTION: The magnesium sulfate comprises 5.0-10.0 wt% of ethylene diamine tetraacetic acid (EDTA); and magnesium sulfate. Preferably the synthetic resin is a thermoplastic resin, and more preferably is an acrylonitrile-butadiene-styrene resin.
