Pali mitundu iwiri yamapaipi omwe ali ndi mizere: 1. Chitoliro chothina.Amadziwika kuti kukoka chubu, ndiye kuti, chitoliro cha tetrafluoro chokulirapo pang'ono kuposa chubu chachitsulo mkati mwake, kudzera pamakina omakoka mu chubu chachitsulo 2.Palipi lotayirira.ndiye m'mimba mwake akunja kwa chitoliro cha tetrafluoro ndi chocheperako pang'ono kuposa m'mimba mwake mkati mwa chitoliro chachitsulo, chomwe chimalumikizidwa mwachindunji mupaipi yachitsulo kudzera pakulowetsa pamanja.

zinthu zazikulu: - PTFE (F4) ndi oyenera kupereka amphamvu zikuwononga sing'anga ≤120 ℃, monga kuchepetsa HCl, HNO3, H2SO4, HF, NaOH, etc - PE utumiki kutentha ≤80 ℃, oyenera ambiri ofooka zikuwononga sing'anga zoyendera, dzimbiri kukana ndi ambiri - PP ndi PO kutentha utumiki ≤100 ℃, oyenera pang'ono zosungunulira zikuwononga sing'anga zoyendera, kukana dzimbiri zambiri

Chikombolecho chimayikidwa mu chitoliro choyenera, ndipo ufa wa tetrafluorin umalowetsedwa m'menemo kuti upangire compaction.

Main zakuthupi: - PTFE F4 ndi oyenera kupereka amphamvu zikuwononga sing'anga ≤150 ℃, monga kuchepetsa HCl, HNO3, H2SO4, HF, NaOH, ndi zina zotero.- Kugwiritsa ntchito PFA potumiza media zowononga ≤200 ℃, mawonekedwe ena ndi ofanana ndi PTFE

Pamwamba pazitsulo za chitoliro zimapangidwira, ndiye zopangira zitoliro zimatenthedwa, ufa wa ETFE umayikidwa mu chitoliro kutentha kukafika pamtunda, ETFE mumtundu wosungunuka umagwirizanitsidwa mofanana ndi khoma lamkati la zipangizo kupyolera mu kuzungulira kwa 3D, ndi potsiriza kuziziritsa ndi kupanga.Main zakuthupi: ETFE (F40), popereka ≤150 ℃ wamphamvu zikuwononga sing'anga, monga kuchepetsa HCl, HNO3, H2SO4, HF, NaOH, ndi zina zotero.Nthawi zambiri amatha kukana kukakamiza kwa micro - negative
