HNBR O-rings 70shore-A 80shore-A 90shore-A PTFE COATED

● Mafuta a petroleum ndi mafuta a R134a gasi refrigerant Mafuta a silikoni ndi girisi Mafuta a ozoni, mikhalidwe yabwino yokanikizira mafuta a masamba ndi nyama Madzi Madzi ndi nthunzi (mpaka 300° F)Kutentha kudzagwira ntchito kuzinthu zambiri zoulutsira mawu zomwe zitha kulangizidwa. .

● Ndi zofalitsa zina komabe, kutentha kwa utumiki kungakhale kosiyana kwambiri.

● Hydrogenated Nitrile (HNBR) o-rings, yomwe imadziwikanso kuti Highly Saturated Nitrile (HSN), imapangidwa ndi polima yopangira yomwe imapezeka podzaza ma bond awiri mu zigawo za nitrile=s butadiene ndi hydrogen.

● Njira yapaderayi ya hydrogenation imachepetsa maunyolo ambiri opangidwa ndi ma polima a NBR. Njirayi imabweretsa kutentha kwapamwamba, ozoni, kukana kwa mankhwala ndi mawonekedwe a makina a HNBR pamtundu wa Nitrile.HNBR o-rings akupezeka mu 70 durometer, 80 durometer, ndi 90 durometer.

● HNBR o-rings ndi yabwino kugwiritsidwa ntchito ndi mafuta ndi mafuta opangidwa ndi petroleum, aliphatic hydrocarbons, mafuta a masamba, mafuta a silikoni ndi girisi, ethylene glycol, madzi ndi nthunzi (mpaka 300ºF), ndi ma asidi osungunuka, mabasi, ndi mchere.Ma o-rings a HNBR samakonda kugwiritsidwa ntchito ndi ma hydrocarboni a chlorinated, ma ketoni, ma ether, esters, ndi ma acid amphamvu.

● Kukula:Zonse za AS-568 BS zitha kukupatsirani zowonjezera zomwe titha kuzipanga malinga ndi zomwe mukufuna!
