PTFE elu-okpomọkụ ákwà na-ọtụtụ-eji na chemical ụlọ ọrụ asaa isi ngwa: flange gaskets na ọkpọkọ linings (na-eguzogide ike acids / alkalis), chernobyl na tank linings (na-egbochi metal corrosion, mfe ihicha), iyo akpa maka corrosive flue gas (ruo 260 ° C), mgbochi corrosion mgbasa nkwonkwo maka ducts

PTFE akwa akwa okpomọkụ kwụsiri ike ruo 300 ° C, mana n'ime ọkụ ọ na-emebi ma na-ahapụ gas na-egbu egbu: hydrogen fluoride (HF) (corrosive, pulmonary edema) na perfluoroisobutylene (PFIB) (enweghị agba, enweghị isi, ~ 10x karịa phosgene, enweghị ọgwụ mgbochi). Ọzọkwa carbon monoxide, PFOA foduru, na trace dioxins. Ihe mkpuchi anwụrụ ọkụ nkịtị adịghị arụ ọrụ; jiri ngwa iku ume na-ejide onwe ya (SCBA). Enwere ike igbu oge mgbaàmà.

Elu emecha mmadụ etinyere na fiberglass ákwà tupu PTFE mkpuchi dị oké egwu maka ikpeazụ PTFE elu-okpomọkụ ákwà ịrụ ọrụ. Ndị na-ahụ maka njikọta Organosilane na-emepụta àkwà mmiri molekụla n'etiti eriri iko inorganic na PTFE organic, na-akwalite ike bee site na <2 N/cm ruo 4-8+ N/cm. Ọgwụgwọ nke ọma na-emekwa ka nguzogide okpomọkụ (260°C+), ịrụ ọrụ dielectric, na nguzogide kemịkal. Akwa akwa na-adịghị edozi na-eduga na delamination, na-agbapụta, na obere ọrụ ndụ.

Nhicha na mmezi nke ọma na-agbatị ndụ PTFE akwa okpomọkụ dị elu. Dị ọcha mgbe ejiri ya na mgbe ọ dị jụụ. Jiri brush dị nro, ihe na-anọpụ iche, ma ọ bụ mmanya maka ntụpọ. Ejila acid/alkalis siri ike, ịcha ọcha, ma ọ bụ nchara ígwè. Mmanya mmanụ silicone mgbe niile na-ebelata iyi. Soro ntuziaka ndị a iji gbochie mmebi mkpuchi.
