Description

Light stabilizer 3853 is an efficient high molecular weight hindered amine light stabilizer. It is insoluble in water and easily soluble in organic solvents such as toluene. Light stabilizer 3853 is mainly used as a 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-acrylic copolymer (ASA), impact-resistant polystyrene (HIPS), thermoplastic polyolefin elastomer (TPO), and polyurethane (PU), etc. It is widely used in the fiber, film, board (sheet), tube, tape, molding and other products made of the above materials. In addition, it is also an antioxidant additive for ashless lubricants.

Advantage

Among polyolefin substrate products, Light stabilizer 3853 has excellent performance in terms of color stability, gloss retention and durability.

Compared with other small molecular weight hindered amine light stabilizers, light stabilizer 3853 has excellent compatibility and solubility with polyolefins, which greatly reduces precipitation and blooming.

Light stabilizer 3853 has good synergistic effects with other high molecular weight hindered amine light stabilizers, benzoate light stabilizers, and ultraviolet absorbers.
