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, kudzitsuka pawokha (madzi amvula amatsuka dothi), kufalitsa kuwala kofewa (6-13%), Kuyeza moto kwa Gulu A, ndi mphamvu ngati chitsulo pansi pa 1.5 kg/m². Amagwiritsidwa ntchito m'mabwalo amasewera, ma eyapoti, ndi nyumba zodziwika bwino padziko lonse lapansi.
