Light stabilizer 783

 

Product performance: light stabilizer 783 is the latest generation of polymeric high molecular weight hindered amine light stabilizer composite products, with good processing thermal stability, good compatibility and water extraction resistance. By capturing free radicals, eliminating the harm of free radicals, decomposing hydroperoxides, quenching excited state energy and other mechanisms, the product can play a low concentration and high efficiency role in anti photo thermal degradation. The mechanism of different hindered amine light stabilizers is the best complementary in this system. The role of active groups has been strengthened and the synergy has been brought into full play. This product is an excellent universal light stabilizer for both thick and thin products with superior price performance ratio.

Main uses: This product is used as a general-purpose excellent light stabilizer for high polymers. It can be used for anti thermal aging of polyethylene, polypropylene, polyurethane, polyoxymethylene, polyamide and polyester elastomer. It can also be used in ABS and engineering plastics. Applied in LDPE or LLDPE agricultural film system, in the application of reducing concentration, this product has better price performance ratio than the best hindered amine light stabilizer at present.

 

Packing: 25kg cardboard bucket, lined with plastic bag.
