High thermal stability for extended processing at elevated temperatures.
Effective phosphite-based hydroperoxide decomposer, preventing oxidative degradation during polymer processing.
Low volatility and excellent compatibility with polyolefins, ABS, and engineering thermoplastics.
Non-staining and color-stable—preserves clarity and hue in sensitive applications such as transparent packaging films.
Complies with major food-contact regulations including FDA 21 CFR §178.2010 and EU Regulation (EC) No 10/2011 (when used within specified limits).
Polypropylene (PP) and polyethylene (PE) injection-molded automotive parts.
Blown and cast polyolefin films for food packaging and agricultural mulch.
ABS and HIPS components in consumer electronics housings.
Engineering plastics blends requiring long-term thermal aging resistance.
Recycled polymer streams where enhanced melt stability is critical during reprocessing.
