Buna-N 70 thawj O-rings

Raj Mis OD: 3/32 "

Kov-N O-Rings 70 Duro (NBR):

Feem ntau siv elastomer rau sealing cov khoom. Nitrile, tseem hu ua Buna-N lossis NBR, yog ib tug copolymer ntawm Butadiene thiab Acrylonitrile. Nws muaj qhov kub thiab txias ntawm -40F rau + 250F thiab tsuas yog siv cov roj av roj thiab cov roj hlawv roj carbon monoxide. Nitrile cov ntaub ntawv kuj muaj lub zog tensile zog thiab txav ntawm cov khoom ua haujlwm. Cov khoom ua tau zoo nrog cov roj kua ntau ntau, roj kua roj, thiab lubricants thiab hauv cov dej siv dej. Nws tsis pom zoo siv nrog cov ketones, cov ntxhuav hydrocarbons, thiab phosphate ester hydraulic fluids. Ntau tshaj 50% ntawm Orings muag yog Nitrile O-rings, feem ntau siv hydraulic / pneumatic motors, thooj plhaub, twj, thiab li qub.
