Highly effective long-term UV stabilization for polyolefins and engineering plastics.
Excellent thermal stability up to 280 °C, suitable for high-temperature processing such as injection molding and extrusion.
Low volatility and minimal migration, ensuring consistent performance in thin-gauge and long-life applications.
Compatible with other additives including antioxidants, UV absorbers, and pigments without adverse interactions.
Non-discoloring formulation preserves original color integrity and surface aesthetics under prolonged UV exposure.
Polypropylene (PP) automotive interior components including dashboards, trim, and door panels.
HDPE and LDPE agricultural films requiring extended outdoor durability and photochemical resistance.
PP and PE nonwovens used in geotextiles, landscaping fabrics, and outdoor furniture covers.
Exterior profiles and cladding made from PVC and thermoplastic elastomers (TPEs).
Rotomolded polyethylene tanks and containers exposed to continuous sunlight and weathering.
