The Application of Complex Light Stabilizers on Polyolefin

The development of polyolefin light stabilization technique was summarized.The results showed that the light stabilizer BHW1 by adding component chelating metal ion in HALS complex had better light stability and balanced performance than other HALS complex.The light stability of hindered amine light stabilizers(HALS) complex could be better than single HALS in natural insolating experiment and farmland experiment.The complex of light stabilizers was the best efficient method of polyolefin anti-aging.
