High molecular weight polymeric hindered amine light stabilizer (HALS) with excellent long-term UV protection.
Low volatility and low extractability, ensuring superior retention in demanding processing and end-use conditions.
Excellent compatibility with polyolefins, engineering plastics, and elastomers without blooming or plate-out.
Thermally stable up to 300 °C, suitable for high-temperature extrusion and injection molding processes.
Synergistic performance when combined with UV absorbers (e.g., Tinuvin 326 or 327) and antioxidants.
Polypropylene (PP) fibers for outdoor geotextiles and agricultural nets.
Automotive interior and exterior plastic components exposed to sunlight.
Rotomolded polyethylene (PE) tanks and containers for water storage and chemical handling.
Blown and cast films used in greenhouse covers and silage wrapping.
Thermoformed packaging trays requiring extended shelf-life under ambient lighting.
