UV327 for acrylic polymers , red - shifted UV absorption Tinuvin
Quick Detail :
UV 327 is a UV absorber of the hydroxyphenylbenzotriazole class,
which imparts out - standing light stability to plastics and other
organic substrates .
- Name : UV327
- Chemical name : 2 - ( 2' - Hydroxy - 3' , 5' - di - tert -
butylphenyl ) - 5 - chlorobenzotriazole
- CAS No. : 3864 - 99 - 1
UV326 exhibits strong absorbance in the 300 - 400nm region and
minimum absorption in the visible region ( ＞ 40nm ) of the spectrum
. The absorption maximum area is at 314nm and 353 nm in chloroform
UV 327 is a highly effective light stabilizer for a variety of
plastics and organic substrates . Due to its red - shifted UV
absorption , it is particularly suited for use in the stabilization
of polymers that are especially sensitive to long - wave length UV
radiation and in certain applications where every low transmission
of long - wave length UV radiation is required . It does a good
performance in acrylic polymers , PP , PE , and so on .
