NAUGARD™ XL-1

Dual function antioxidant and metal deactivator, designed for use in polyolefins and polystyrenics that have residual metallic ions as a result of mineral fillers, inorganic pigments, or catalysts.
Product Overview
NAUGARD™ XL-1 combines an antioxidant and a metal deactivator for outstanding protection in variety of polyolefin and polystyrene systems. It is especially useful in resin systems that are mineral filled or have residual metallic ions from catalysts and inorganic pigments. NAUGARD™ XL-1 is non-discoloring and FDA regulated for use in most polymers.
