Molecular Structural Formula:

Applications: This product is a hindered amine light stabilizer, primarily used as an ultraviolet light stabilizer for thermoplastic polymer materials such as polyacetal, acrylonitrile-butadiene-styrene copolymer (ABS), and styrene-acrylonitrile copolymer (SAN); engineering plastics such as polyethylene (PE), polypropylene (PP), polyamide (PA), acrylonitrile-styrene-acrylate copolymer (ASA), and high-impact polystyrene (HIPS); thermoplastic polyolefin elastomers (TPO), and polyurethane (PU). It is widely used in fibers, films, sheets, pipes, belts, moldings, and other products made from the above materials. Additionally, it serves as an antioxidant additive for ashless lubricants.

This product has the following features: 1. It exhibits good synergistic effects with other hindered amine light stabilizers, especially high molecular weight hindered amine light stabilizers (e.g., 944, 119) and benzoate UV absorbers (e.g., UV328). 2. In polyolefin-based products, it provides excellent color stability, gloss retention, and durability. 3. Compared to other low molecular weight hindered amine light stabilizers, it has good compatibility and solubility with polyolefins.

Storage: Store in a sealed container in a cool, dry place.

Packaging: 25kg, 180kg/drum or as per customer requirements.

Shelf Life: 1 year.
