Nsalu yotentha kwambiri ya PTFE (PTFE- TACHIMATA fiberglass) ndi yabwino kwa malamba otumizira chakudya chifukwa cha 260°C kukana kutentha, -70°C kusinthasintha kuzizira, pamwamba osagwira ndodo, ndi kutsata kwa FDA. Ntchito zazikuluzikulu: mauvuni ophika buledi (mabisiketi, buledi, pitsa), zotengera zakudya zokazinga, mizere yozizirira maswiti, machubu oziziritsa, zosindikizira kutentha, ndi zokutira zogudubuza. Amachepetsa kutaya ndi kuyeretsa nthawi.

Calendering - kukanikiza nsalu yokutidwa ndi PTFE pakati pa zodzigudubuza zagalasi zotenthetsera pa 360-380 ° C - zimasintha kwambiri kapangidwe kapamwamba, kutulutsa katundu, kusakwanira, ndi magwiridwe antchito amakina. Amachepetsa roughness kuchokera ku Ra 0.5-1.0 μm kufika ku <0.05 μm, amasindikiza ma pinholes, amathandizira kukana kuvala, koma amachepetsa mphamvu ya misozi ndi kusinthasintha. Zofunikira pakutulutsa ma liner ndi kutchinjiriza kwamagetsi.

Nsalu ya PTFE yotentha kwambiri (PTFE membrane material) ndi chisankho choyambirira pamamangidwe olimba. Ubwino waukulu: zaka 30+ za moyo wapanja, kudziyeretsa pawokha (madzi amvula amatsuka dothi), kufalitsa kuwala kofewa (6-13%), Kuyeza moto kwa Gulu A, mphamvu zonga chitsulo zosakwana 1.5 kg/m². Amagwiritsidwa ntchito m'mabwalo amasewera, ma eyapoti, ndi nyumba zodziwika bwino padziko lonse lapansi.

Kulowetsedwa kwa PTFE sikungokhala ndi nsalu za fiberglass. Nkhaniyi ikuwonetsa magawo asanu ndi awiri amtundu wina - aramid, carbon fiber, PBI, porous metal, graphite, asbestos (ochotsedwa), ndi zodzaza ndi ceramic - ndi machitidwe awo, ubwino, malire, ndi ntchito zazikulu.
