UV328 exhibits strong absorbance in the 300 - 400nm region and
minimum absorption in the visible region ( ＞ 400nm ) of the
spectrum . The absorption maximum area is at 308nm and 349nm in
chloroform solution .
UV 360 applications include acrylic resins , polyalkylene ,
terephthalates , PP , modified polyphenylene ether or sulfide
|Assay (GC)||99% min|
|Transmittance||460nm 97.0% min|
|500nm 98.0% min|
Competitive Advantage :
UV 360 is particularly suited for processing and aging conditions
where high loads , low volatiles and high compatibility are
required . The specific objective is to achieve UV - screen
performance and minimize sublimation through vents as well as
deposits on molds , chill-rolls and calibrators .
Hongkun is one of the important manufacturers of UV328 in China
with the same quality of BASF , and the application effect has been
proved by many customers .
