Ikigo cy’Uburayi gishinzwe imiti (“ECHA”) cyasohoye dosiye yuzuye yerekeye itegeko ribuza ibiyobyabwenge bigera ku 10.000 kuri buri kimwe na polyfluoroalkyl ("PFAS"). PFAS ikoreshwa mu nganda nyinshi kandi iboneka mu bicuruzwa byinshi. Iri tegeko rigamije kubuza ikorwa, gushyira ku isoko no gukoresha ibintu byangiza ubuzima bw’abantu n’ibidukikije, no kugabanya ingaruka zijyana nabyo.
Mu nganda zacu, PFAS ikoreshwa nk'ubushyuhe bw'inyuma bw'insinga za LItz, ibikoresho bifatika ni Polytetrafluoroethylene (PTFE), ethylene-tetrafluoroethylene (ETFE), cyane cyane ETFE ni ibikoresho byiza cyane birwanya UV, ozone, peteroli, aside, bases ndetse n'amazi adapfa.
Kubera ko amategeko y’i Burayi azabuza PFAS yose, ibyo bikoresho bizaba amateka vuba aha, abakora mu nganda bose bagiye bashaka ibindi bikoresho byizewe, ku bw’amahirwe twabonye ko TPEE ari yo ikwiye.
Elastomer ya TPEE Thermoplastic Polyester, ni ibikoresho bifite imikorere myiza kandi bishyushye cyane, bifite imiterere myinshi ya thermoset rubber ndetse n'imbaraga za pulasitiki zo mu rwego rwa tekiniki.
Ni copolymer y'igice cy'ingenzi irimo igice gikomeye cya polyester n'igice cyoroshye cya polyether. Igice gikomeye gitanga ubushobozi bwo gutunganya nk'iplastike mu gihe igice cyoroshye kiyiha ubushobozi bwo koroshya. Ifite imikorere myinshi myiza kandi ikunze gukoreshwa mu bikoresho by'amashanyarazi, ikoranabuhanga n'inganda z'imodoka.
Icyiciro cy'ubushyuhe bw'ibikoresho: -100℃～+180℃，urutonde rw'ubukomere: 26～75D，
Ibintu by'ingenzi biranga TPEE ni
Ubudahangarwa bwiza bwo kurwanya umunaniro
Ubushobozi bwiza bwo kwihangana
Ubudahangarwa bw'ubushyuhe bwinshi cyane
Irakomeye, irinda kwangirika
Ingufu nziza zo gukurura
Irwanya amavuta/imiti
Ubudahangarwa bukomeye
Imiterere myiza ya mekanike
Tuzagerageza kubagezaho ibikoresho byinshi kugira ngo bihuze n'ibyo mukeneye. Kandi murakaza neza kuduha inama ku bikoresho bikwiranye.
