Lekala la Lik'hemik'hale la Europe ("ECHA") le phatlalalitse tokomane e felletseng mabapi le thibelo ea lintho tse ka bang 10,000 ka 'ngoe le tse nang le li-polyfluoroalkyl ("PFAS"). Li-PFAS li sebelisoa liindastering tse ngata 'me li teng thepa e ngata ea bareki. Tlhahiso ena ea thibelo e ikemiselitse ho thibela tlhahiso, ho beha 'marakeng le ts'ebeliso ea lintho tse kotsi bophelong ba batho le tikolohong, le ho fokotsa likotsi tse amanang le tsona.
Indastering ea rona, PFAS e sebelisoa e le ho thibela ho kenella ha terata ea LItz ka ntle, thepa e amehang ke Polytetrafluoroethylene (PTFE), ethylene-tetrafluoroethylene (ETFE), haholo-holo ETFE ke thepa e loketseng haholo ho hanela UV, ozone, oli, li-acid, metheo le metsi ka hohle kamoo ho ka khonehang.
Kaha melao ea Europe e tla thibela PFAS eohle, thepa e joalo e tla fetoha nalane haufinyane, litsebi tsohle tsa indasteri li ntse li batla thepa e 'ngoe e tšepahalang, ka lehlohonolo re ile ra hlokomela ho mofani oa rona oa thepa hore TPEE ke eona e nepahetseng.
Elastomer ea TPEE Thermoplastic Polyester, ke thepa e sebetsang hantle haholo, e nang le mocheso o phahameng e nang le likarolo tse ngata tsa rabara ea thermoset le matla a polasetiki ea boenjiniere.
Ke copolymer ea boloko e nang le karolo e thata ea polyester le karolo e bonolo ea polyether. Karolo e thata e fana ka thepa ea ts'ebetso joalo ka polasetiki ha karolo e bonolo e e fa monyetla oa ho tenyetseha.

Likarolo tse ka sehloohong tsa TPEE ke
Ho hanyetsa mokhathala hantle haholo
Ho mamella mathata hantle
