Tinuvin 783Usage
1.Copolymerized HALS with excellent and long lasting stabilizing effect against light and heat, low volatility, hardly extractable, particularly suitable for PP fibre, tape, thin and thick LLDPE, LDPE products.
2.Light stabilizer 783 is a general-purpose excellent light stabilizer for high polymer. It can be used for light-proof aging of polyethylene, polypropylene, polyurethane, polyoxymethylene, polyamide and polyester elastomers. Light stabilizer 783 is also widely used. In ABS and engineering plastics, it is used in LDPE or LLDPE agricultural film systems. In applications where concentration is reduced, light stabilizer 783 has a superior price-performance ratio than the most excellent hindered amine light stabilizers available.
