Lesela la PTFE le nang le mocheso o phahameng oa mocheso (PTFE-coated fiberglass) le na le khanyetso e ntle haholo ea mocheso ka har'a mefuta e tloaelehileng ea ts'ebetso ea -70 ° C ho isa ho 260 ° C. E ka mamella ho palama baesekele ka potlako, mohlala, ho tloha sehatsetsing sa -50 ° C ho ea ho mochine o chesang oa 260 ° C. Limaraka tsa pele li bile li pholoha ho pholile ka tšohanyetso ho tloha ho 260 ° C ho ea ho 10 ° C metsi. Leha ho le joalo, ho tšosa thepa ho tloha mocheso o ka holimo ho 300 ° C (haufi le ntlha ea ho qhibiliha ea PTFE ea 327 ° C) ho tla baka ho phunyeha le ho senya hang-hang. Fiberglass substrate e fana ka botsitso ba dimensional; ho roala PTFE ke ntlha e fokotsang.

FDA le limaraka tsa UL lia fumaneha.

Lesela la mocheso o phahameng oa PTFE le tsitsitse ho fihlela ho 300 ° C, empa mollong lea bola le ho ntša likhase tse chefo haholo: hydrogen fluoride (HF) (corrosive, pulmonary edema) le perfluoroisobutylene (PFIB) (e se nang mebala, e sa nkheng, ~10x e chefo ho feta phosgene, antido).
