UV327 for acrylic polymers , red - shifted UV absorption Tinuvin 327

Quick Detail :

UV 327 is a UV absorber of the hydroxyphenylbenzotriazole class, which imparts out - standing light stability to plastics and other organic substrates .

Description :

1. Name : UV327
2. Chemical name : 2 - ( 2' - Hydroxy - 3' , 5' - di - tert - butylphenyl ) - 5 - chlorobenzotriazole
3. 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 solution .

Applications :

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 .

Specifications :

Competitive Advantage :

TINUVIN 327 is especially suited foracrylic polymers , PP and PE.

Hongkun is one of the important manufacturers of UV327 in China with the same quality of BASF , and the application effect has been proved by many customers .
