Silicone muaj lub siab melting taw tes thiab tuaj yeem siv tau los ntawm cov neeg siv kub ntawm rho tawm 60 degrees Celsius thiab 200 degrees Celsius. Thiab silicone yog kev nyab xeeb heev thiab txhim khu kev qha, yog li hauv cov ntawv thov thiab cov teb uas siv, silicone roj hmab sursed. Thiab kev tsim khoom ntawm silicone roj hmab series roj hmab Rings yuav tsum tau sim cov cuab yeej ua kom zoo tshaj plaws thiab huv si {}}} recew rovice. Yog li ntawd, silicone roj hmab series cov roj hmab nplhaib khoom yog dav siv nyob rau hauv kev lag luam xws li cov khoom siv kho mob, thiab khoom noj.
Polytetrafluoroethylene muaj cov yam ntxwv ntawm cov kub ua tsis kam thiab muaj zog corrosion tsis kam. Yog li no, cov roj hmab rings tsim los ntawm cov neeg pleev kob uas siv ethylene yuav tsis ua haujlwm txawm tias thaum raug kub thiab oxidants muaj zog thiab oxidants. Ntxiv mus, polytetrafluoroethylene tau siv dav ua cov khoom sealing vim nws tus nqi qis thiab kev ua tau zoo hauv kev ua cov roj hmab ib ncig. PTFE series cov nplhaib roj hmab ib ncig yog siv dav siv raws li cov khoom siv sealing ntawm cov raj xa khoom ntawm cov raj, cov khoom siv cov nkoj, thiab ntim khoom.
Tsis zoo li lwm cov ntaub qhwv, qhov no yog homogeneous elastic ntxeem cov khoom. Tsis tsuas yog nws yog nws muaj cov elasticity roj hmab, tab sis nws kuj muaj cov khoom zoo ntawm cov hlau. Nws tuaj yeem ua haujlwm ntawm kev rho tawm los ntawm rho tawm 150 degrees rau 800 degrees Celsius, thiab muaj cov Cegrosion zoo heev thiab Compression Kuj. Cov roj hmab rings siv rau kev sib khi ntawm cov kav dej ntws los ntawm Tsoomfwv Tsoomfwv Tam sim no yog txhua tus neeg siv roj hmab sib tw. Vim tias cov roj hmab hlau muaj kev nyab xeeb thiab txhim khu kev qha, cov roj hmab seadinging pipelines kuj yog cov roj hmab sib khi nplhaib.
