Superiority

1.chemical name

2-[2'-hydroxy-3',5'-di-t-butyl-phenyl]-benzotriazole
2.introduction
uv-320 is a highly effective light stablizer for a variety of plastics and other organic substrates including unsaturated polyesters , pvc and pvc plastisol. good results are also expected when uv-320 is used in polycarbonates. polyurethanes. polyamides. synthetic fibers. particularly those with a polyester, epoxy resin base. uv-320 features strong uv absorption excellent compatibility in a variety of substrates and low volatility and protects polymers as well as organic pigments from uv radiation helping to preserve the original appearance and physical integrity of molded articles, films, sheets and fibers during outdoor weathering,
3. molecular formula : c20h25n3o

4. molecular weight : 323.4

5. cas no : 3846-71-7
6. chemical structure :

7. the sale code name : ps-320
8. physical properties
appearance : slightly yellow powder
assay : ≥ 99%
melting point : 152-154 °c
loss on drying : ≤ 0.5%
ash : ≤ 0.1%
transmittance: 440nm≥97%
500nm≥98%
9. storage and transportation :

the chemical stability is good.it can be stored and transpoted according to the general chemical matter regulation.
