UV-P yog benzotriazole hom UV absorber - ADSORB P
cov khoom nthuav dav
Tshuaj Lub Npe: 2-(2H-Benzotriazol-2-yl)-p-cresol Synonyms: Drometrizole; UV-P; Tinuvin P Taw Qhia UV-P yog benzotriazole hom UV absorber. Nws muaj qhov nqus dej siab hauv nthwv dej ntev ntawm 270 ~ 340nm. Nws tseem ua tau zoo rau lub teeb stabilization ntawm polyvinyl chloride, unsaturated polyurethane, polystyrene, coatings thiab lacquers. CAS No.: 2440-22-4 Chemcial Structure: Specification Appearance: white to yellowish crystal hmoov Melting Point: 128 ~ 131 ℃ Cov ntsiab lus (HPLC): 99% Min. Transmittance: 440nm≥97% 500nm≥98% tshauv: 0.1% Max. Volatiles: 0.5% Max. Pob: 25KG Carton Description ADSORB® P nta lub zog nqus ntawm ultraviolet hluav taws xob hauv thaj tsam 300-400nm. Nws kuj tseem muaj qhov siab ntawm kev yees duab-kev ruaj ntseg nyob rau lub sijhawm ntev ntawm lub teeb raug. ADSORB® P muab kev tiv thaiv ultraviolet hauv ntau hom polymers nrog rau styrene homo- thiab copolymer, engineering plastics xws li polyesters thiab acrylic resins, polyvinyl chloride, thiab lwm yam halogen uas muaj cov polymers thiab copolymer (xws li vinylidenes), acetals thiab cellulose esters. Elastomers, adhesives, polycarbonates, polyurethanes, thiab qee cov cellulose esters thiab epoxy cov ntaub ntawv kuj tau txais txiaj ntsig los ntawm kev siv ADSORB® P. Property a) Tsis muaj ntxhiab tsw, tsis txhob hnov qab txog polymers. b) Insensitive rau hlau ion c) Tsis-flammable, non-explosion, non-toxic, harmless rau kev noj qab haus huv. d) Cov duab zoo heev rau nws lub zog muaj peev xwm nqus lub teeb tshwj xeeb tshaj yog nyob rau hauv cheeb tsam UV (270 ~ 340nm) e) ruaj khov rau cua sov thiab tuaj yeem siv rau hauv cov yas uas yuav tsum tau ua haujlwm kub. f) Tsis tshua pom lub teeb pom kev, tshwj xeeb tshaj yog tsim rau cov khoom tsis muaj xim thiab cov khoom siv xim xim. Toxicity & Safety UV-P tuaj yeem ua haujlwm raws li kev lag luam chemical uas muab cov kev ceev faj txog kev tuav tes hauv qab no nruj me ntsis raws li: a) Hnav hnab looj tes kom tsis txhob sib cuag nrog daim tawv nqaij. Khaws thaj chaw ua haujlwm kom huv si thiab muaj cua zoo. Hnav looj tsom iav dub thiab lub ntsej muag lub ntsej muag thaum twg cov plua plav tsis tuaj yeem tiv thaiv kom tsis txhob khaus qhov muag thiab ua pa. Pob: Net 25kg ntawv nruas lossis thawv. Cia: UV-P yuav tsum muab cia rau hauv lub kaw lus kaw thiab khaws cia rau hauv qhov chaw qhuav thiab txias. IPG yog tsom rau cov yas zoo tshuaj additives / master batches nrog lub ntiaj teb no muaj nyob.
