Ukufakwa kwe-PTFE akuphelelanga kwilaphu le-fiberglass. Eli nqaku lizisa ii-substrates ezi-7 ezizezinye - i-aramid, i-carbon fiber, i-PBI, isinyithi esine-porous, i-graphite, i-asbestos (ikhutshwe ngaphandle), kunye ne-ceramic fillers - kunye neempawu zabo zenkqubo, izibonelelo, ukulinganiselwa, kunye nezicelo eziphambili.

Eli nqaku licacisa ukuba kutheni ilaphu le-fiberglass engena-alkali iyeyona ikhethwayo kwilaphu le-PTFE lobushushu obuphezulu. Igquma ukudityaniswa kweekhemikhali kusetyenziswa i-silane coupling agents kunye neepropathi eziphambili zomzimba ezifana nokuzinza kwe-thermal, ukuzinza komda, kunye nokuxhathisa umhlwa-ukuqinisekisa ukusebenza okuhlala ixesha elide kwiindawo ezinzima.

I-Jiangsu Aokai New Material, umenzi ophambili we-PTFE welaphu lobushushu obuphezulu, wabelana ngolwazi lobuchwephesha: Imigca ethe tyaba kunye nepateni yelifu umahluko wombala kwilaphu lobushushu obuphezulu be-PTFE ngokubalulekayo kubonakaliswa kobunzima obungalinganiyo bokugquma kunye nokusabalalisa uxinzelelo olungalinganiyo.
