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