Highly effective long-term thermal and photo-oxidative stabilization for polymers exposed to UV radiation.
Low volatility and excellent compatibility with a broad range of thermoplastics and elastomers.
Non-discoloring performance—maintains clarity and color stability in sensitive applications.
Acts synergistically with UV absorbers (e.g., benzotriazoles) and antioxidants for enhanced protection.
Resistant to extraction and migration, ensuring durable stabilization during processing and end-use.
Polyolefins: PP and PE fibers, films, blow-molded containers, and automotive interior parts.
Engineering plastics: ABS, PC/ABS blends, and polyesters used in outdoor consumer electronics housings.
Coatings and inks: High-performance industrial coatings requiring extended gloss and chalking resistance.
Adhesives and sealants: UV-stable formulations for solar panel encapsulation and architectural glazing systems.
Geotextiles and agricultural films: Long-life geomembranes and mulch films subjected to intense sunlight exposure.
