2. Kev ua haujlwm ruaj khov nyob rau hauv qhov dav ntawm qhov kub thiab txias: Featuring zoo tshuaj inertness thiab durability, nws muaj kev ntseeg siab nyob rau hauv cov huab cua ntawm kub ntawm -40℃mus rau 400 degree, thiab mus txog rau 3000℃nyob rau hauv ib tug inert gas ib puag ncig. Nws tsis tshua muaj thermal expansion coefficient tiv thaiv tawg los yog deformation los ntawm thermal stress, txawm nyob rau hauv hnyav huab cua kub tej yam kev mob, nrog ib tug kev pab cuam lub neej tshaj 5 xyoo nyob rau hauv ib txwm ua hauj lwm.
3. Lub teeb thiab yoog raws: Nrog rau qhov ceev ntawm 1.0–1.8 g / cm³ -75% sib zog dua tooj liab- nws los ntawm ultra-thin thicknesses ntawm 0.03mm mus rau 50mm. Nws tuaj yeem khoov 90℃yam tsis muaj kev tawg, thiab yooj yim rau kev txiav, pwm, lossis laminate nrog cov nplaum thiab zaj duab xis, tso cai rau nws kom haum nruj rau ntau qhov chaw tsis sib xws rau kev sib xyaw ua ke rau hauv cov khoom sib txawv.
4. Corrosion Resistance thiab Environmental Protection: Nws muaj zog tiv thaiv rau feem ntau cov kua qaub, alkalis, thiab ntsev - nrog rau qhov poob qis ntawm tsis pub ntau tshaj 0.5% tom qab 72 teev ntawm immersion nyob rau hauv hnyav tshuaj. Raws li cov khoom siv tsis zoo, tsis yog- cov khoom muaj kuab lom, nws ua tau raws li ROHS thiab REACH ib puag ncig cov qauv, thiab nws cov khoom siv raw tuaj yeem rov ua dua tshiab, ua raws li cov tswv yim tsim ntsuab.
5. Kev Siv Hluav Taws Xob Zoo thiab Tus Kheej {{0}Lubrication: Nws muaj qhov ntim tsawg dua (tsawg dua lossis sib npaug ntawm 0.0001Ω·cm), ua kom muaj hluav taws xob zoo heev. Tsis tas li ntawd, nws muaj tus kheej zoo -lubricating zog, ua rau nws haum rau siv los ua ib tug lubricating tivthaiv nyob rau hauv mechanical kis tau tus mob los txo cov khoom hnav. Rau cov kev cai tshwj xeeb, peb kuj muab kev xaiv electromagnetic shielding kom tsis txhob cuam tshuam electromagnetic.
