High-performance hindered amine light stabilizer (HALS) specifically optimized for polypropylene (PP) compounds.
Excellent melt stability and low volatility, ensuring consistent performance during high-temperature processing.
Superior long-term UV protection in thin-wall and outdoor applications, minimizing surface chalking and embrittlement.
Good compatibility with common PP homopolymers and copolymers, as well as with other additives like antioxidants and nucleating agents.
Pre-dispersed masterbatch format (5% active HALS in PP carrier) enables uniform distribution and simplified handling.
Automotive interior and exterior trim components exposed to sunlight.
Outdoor furniture and garden products requiring weather resistance.
Geotextiles and agricultural films subjected to prolonged UV irradiation.
Household appliances with visible PP housings or structural parts.
Consumer packaging for premium goods requiring extended shelf-life under ambient lighting.
