Properties of Light Stabilizer 783 (CAS 71878-19-8+65447-77-0)
- Light stabilizer 783 (HALS 783) is white granule, soluble in methyl benzene, dimethyl benzene, chloroform and furan etc. insoluble in water, methanol, alcohol and hexane.
- HALS 783 is a polymeric HALS composite, with high molecular weight, good heat stability, consistency and extracting resistance. It has the effect of resisting light and thermal degradation by catching free radicals and clean the harm of free radicals, breaking down hydroperoxide and quenching excited states energy.
- HALS 783 is a versatile UV stabilizer for thin and thick sections and delivers excellent cost/performance benefits.
Applications of Hindered Amine Light Stabilizer 783 (CAS 71878-19-8+65447-77-0)
Hindered Amine Light Stabilizer 783 (HALS 783) can be used in polypropylene(PP), polyethylene(PE), polyurethane(PU), polyformaldehyde(POM), polyamides(PA), polyester elastomer, ABS and LDPE/LLDPE in agricultural system to keep products from light and heat aging. In application of density reducing, HALS 783 has a better cost performance than all the other HALS.
