Light Yellow Low volatility Ultraviolet Absorbers 326 with CAS No. 3896 - 11 – 5


Quick Detail :


UV 326 is a UV absorber of the hydroxyphenylbenzotriazole class , which imparts out - standing light stability to plastics and other organic substrates .


Description :

  1. Name : UV326
  2. Chemical name : 2 - ( 2’ - Hydroxy - 3’ - Tert - Butyl - 5’ - Methylphenyl ) - 5 - Chlorobenzotriazole
  3. CAS No. : 3896 - 11 - 5
  4. Function : Low volatility , Exceptional light absorbing characteristics and good compatibility

TINUVIN 326 has a wide range of indirect food approvals in polyolefins . It has a low volatility at high temperatures and high resistance to thermal degradation and can therefore be used without significant loss or decomposition in the polyolefin compounding and molding processes .


Applications :

In the use for the UV protection of polyester resins , TINUVIN 326 does not form colored complexes with the metallic salts used for the curing process of these resins .

It is recommended to use TINUVIN 326 with a HALS type lightstabilizer system for best results . The recommended concentrations range for PP applications from 0.1 - 0.5% , for PE applications from 0.1% to 0.4% .

The recommended levels for normal polyester resins range from 0.2% to 0.3% , while for chlorinated, flam retardant polyeste resins, the recommendation is 0.5% .
