CAS number: 1843-05-6
EINECS number: 217-421-2
Physical and chemical properties: melting point 47-49 ℃,
the density of 1.160g/cm3, soluble in benzene, hexane, acetone, slightly soluble in ethanol, slightly soluble in two ethyl chloride.
Properties and uses: UV absorber UV-531 is a high performance, anti-aging agent, can absorb ultraviolet 240-340 nm, with light color, non-toxic, good compatibility features, small mobility, easy processing. It has maximum
protective effect on polymer, and help to reduce color, at the same time delay yellowing
and block physical performance loss.Mainly used as a light stabilizer of polyethylene,
polypropylene, PVC, polyurethane rubber and other synthetic materials. Widely used in PE,
PVC, PP, PS, PC, polycarbonate, acrylic, polypropylene fibre and vinyl acetate. But for
dry phenolic and alkyd varnish, polyurethane, acrylic, epoxy and other air drying products
and automotive repair paint, powder coating, rubber products, provide good light-stable effects for them. The amount of 0.1-0.5%.
