High-performance hindered amine light stabilizer (HALS) with exceptional long-term UV protection.
Excellent compatibility with polyolefins, including PP and PE, without blooming or migration issues.
Thermally stable up to 280 °C, enabling use in high-temperature processing such as injection molding and extrusion.
Low volatility and minimal odor—ideal for sensitive applications including automotive interior parts and consumer goods.
Non-basic HALS chemistry minimizes adverse interactions with acid-sensitive additives (e.g., certain flame retardants or pigments).
Automotive exterior and interior plastic components (e.g., bumpers, trim, dashboards).
Polypropylene (PP) and polyethylene (PE) packaging films requiring extended outdoor shelf life.
Garden furniture and building products exposed to direct sunlight and weathering.
Technical textiles and geotextiles made from stabilized spunbond or nonwoven polyolefins.
Household appliances and durable consumer goods with colored polymer housings.
