Light stabilizer 783:
Composite high molecular weight hindered amine light stabilizer
Features:
783 is a mixture of 944 and 622. It is a multi-purpose anti-UV stabilizer. 783 is particularly suitable for low-density polyethylene, linear low-density polyethylene, high-density polyethylene films, flat yarns and thick cross-section products. For polypropylene, it is used for fibers and films; when thick products need to be in direct contact with food, 783 can also be used
Application:
The application range of 783 includes polyolefins (PP, PE), olefin copolymers
Properties and advantages: 783 is a multi-purpose light stabilizer, used for thin and thick products, with excellent cost performance.
Appearance:
White yellowish granules
Guidelines for use:
- Thick products: Anti-UV stabilization of high-density polyethylene, linear low-density polyethylene, low-density polyethylene and polypropylene, add: 0.1-0.8%
