Specification
Ultraviolet absorber UV-234 (tseem hu ua lub teeb stabilizer UV-234) yog benzotriazole chav kawm ultraviolet absorber. Nws muaj txiaj ntsig zoo tiv thaiv cov ntaub ntawv polymer los ntawm photodegradation los ntawm kev hloov cov teeb meem ultraviolet lub zog rau hauv cov hluav taws xob tsis zoo rau kev tso tawm, yog li txuas ntxiv kev pab cuam lub neej ntawm cov khoom.
