UV STABILIZER 783 (CAS NO : 71878-19-8 and 65447-77-0)

UV Stabilizer 783 is a high molecular weight hindered amine light stabilizer (HALS) known for its excellent light stability and long-term thermal stability. It exhibits low volatility, resistance to extraction, and good compatibility with most polymers. This stabilizer is particularly effective in enhancing the durability of polymers exposed to outdoor conditions. UV-783 is a synergistic mixture of UV- 944 and UV-622. It is a versatile UV stabilizer with outstanding extraction resistance, low gasfading and low pigment interaction. UV-783 is particularly well suited for LDPE, LLDPE, HDPE films, tapes and thick sections and for PP in fibers and films. It is also the product of choice for thick sections where indirect food contact approval is required. UV-783 is a versatile UV stabilizer for thin and thick sections and delivers excellent cost / performance benefits. For applications requiring indirect food approvals, TINUVIN 783 can be used at levels not possible with other conventional HALS. The synergism between the two high molecular weight HALS components of UV-783 is an effective stabilization system for the polymer against degradation through UV radiation and long term heat exposure.
