Nta thiab daim ntawv thov

Lub photostabilizer UV770 yog ib qho hnyav molecular hindered amine photostabilizer, uas muaj cov yam ntxwv ntawm kev sib raug zoo, tsis tshua muaj volatility, zoo dispersion, tsis tshua muaj txav, zoo thermal stability thiab siab optical stability, thiab tsis nqus pom lub teeb thiab tsis cuam tshuam xim. Rau qhov siab saum npoo thiab tuab ntu ntawm nqaim band, molding, muaj cov duab zoo heev. Nrog lub siab molecular hnyav lub teeb stabilizer thiab ultraviolet absorber, cov nyhuv synergistic yog qhov tseem ceeb.

Feem ntau siv rau: polyethylene, polypropylene, polystyrene, olefin copolymer, polyester, mos polyvinyl chloride, polyurethane, polyformaldehyde thiab polyamides, adhesives thiab seals thiab lwm yam.
Pom zoo ntxiv tus nqi: feem ntau 0.05-0.60%. Kev ntsuam xyuas tsim nyog yuav tsum tau siv los txiav txim qhov tsim nyog tus nqi ntxiv hauv kev siv tshwj xeeb.
