Properties
It is waxy solid, odorless. Its melting point is 28~32°C, the specific gravity (20 °C) is 0.895. It is insoluble in water and easy to soluble in toluene etc.
Application
Light stabilizer 3853 is a low molecular weight hindered amine light stabilizer, which has excellent compatibility and solubility with polyolefin resins, greatly reducing precipitation and frosting.
It is used in most polymers, including PP products such as injection molding, film materials and tapes, and can also be used as a light stabilizer in polyacetal, polyamide and styrene polymers.
