Polychlorotrifluoroethylene (PCTFE los yog PTFCE) yog ib tug thermoplastic chlorofluoropolymer nrog cov mis mos molecular (CF2CClF)n, qhov twg yog tus naj npawb ntawm monomer units nyob rau hauv lub polymer molecule.Nws zoo ib yam li polytetrafluoroethene (PTFE), tshwj tsis yog tias nws yog homopolymer ntawm monomer chlorotrifluoroethylene (CTFE) es tsis txhob tetrafluoroethene.Nws muaj qhov qis tshaj dej vapor kis tus nqi ntawm txhua yam yas.
Cov khoom 
CTFE muaj lub zog tensile siab thiab zoo thermal yam ntxwv.Nws yog nonflammable thiab qhov kub tsis kam mus txog 175 ° C.Nws muaj qhov tsawg coefficient ntawm thermal expansion.Cov iav hloov pauv kub (Tg) yog nyob ib ncig ntawm 45 ° C.PCTFE muaj ib qhov siab tshaj plaws txwv oxygen index (LOI).Nws muaj tshuaj tiv thaiv zoo.Nws kuj nthuav tawm cov khoom zoo li xoom noo noo nqus thiab tsis ntub dej.Nws tsis nqus pom lub teeb.Thaum raug hluav taws xob hluav taws xob siab, nws nkag mus, zoo li PTFE, degradation.Nws tuaj yeem siv los ua cov duab pob tshab.Lub xub ntiag ntawm cov tshuaj chlorine atom, muaj atomic vojvoog ntau dua li cov fluorine, cuam tshuam cov ntim ze ntawm PTFE.Qhov no ua rau muaj qhov qis qis ntawm cov fluoropolymer, nyob ib ncig ntawm 210-215 ° C.PCTFE tiv taus qhov kev tawm tsam los ntawm feem ntau cov tshuaj thiab oxidizing cov neeg ua haujlwm, cov khoom pov thawj vim muaj cov ntsiab lus fluorine siab.Txawm li cas los xij, nws swells me ntsis hauv cov tshuaj halocarbon, ethers, esters thiab cov kuab tshuaj tsw qab.PCTFE tiv taus oxidation vim nws tsis muaj hydrogen atoms.PCTFE nthuav tawm lub sijhawm dipole mus tas li vim qhov molecular asymmetry ntawm nws qhov rov ua dua tshiab.Lub sijhawm dipole no yog perpendicular rau carbon-chain axis.Cov ntawv thov CTFE pom feem ntau ntawm nws daim ntawv thov vim muaj ob lub ntsiab: dej repulsion thiab tshuaj stability.PCTFE films yog siv los ua cov txheej txheem tiv thaiv kev ya raws.Cov no suav nrog: • noo noo barrier nyob rau hauv tshuaj blister ntim, • dej-vapour barrier rau kev tiv thaiv phosphor txheej hauv electroluminescent teeb (cov tshuaj phosphor yog rhiab heev rau ya raws), kev tiv thaiv ntawm cov kua-crystal zaub (LCD) panels, uas yog rhiab heev rau ya raws.Vim nws cov tshuaj stability, nws ua raws li ib tug tiv thaiv kev tiv thaiv cov tshuaj.Nws yog siv los ua txheej txheej thiab prefabricated liner rau kev siv tshuaj lom neeg.PCTFE kuj tseem siv rau laminating lwm cov polymers xws li PVC, polypropylene, PETG, APET thiab lwm yam. Nws kuj yog siv rau hauv cov tsom iav pob tshab, raj, li qub, tshuaj tank liners, O-rings, seals thiab gaskets.PCTFE yog siv los tiv thaiv cov khoom siv hluav taws xob rhiab heev vim nws cov hluav taws xob zoo heev thiab dej tawm tsam.Lwm yam kev siv suav nrog cov ntawv luam tawm yooj yim thiab rwb thaiv tsev ntawm cov xov hlau thiab cables.Low-molecular-weight PCTFE waxes, oils and greases pom lawv daim ntawv thov ua inert sealants thiab lubricants.Lawv kuj tau siv los ua gyroscope flotation fluids thiab plasticizers rau thermoplastics.
