Njira zina zothetsera PPA pansi pa zopinga za PFAS

PPA (Polymer Processing Additive) yomwe ndi fluoropolymer processing aids, ndi fluoropolymer polima-based structure of polima processing aids, kuti apititse patsogolo ntchito polima polima, kuthetsa kusungunuka kuphulika, kuthetsa kufa buildup, kusintha sharkskin, ndi zina zotero. Idapangidwa koyamba ndi DuPont mu 1961 ndikuyika pamsika m'zaka za m'ma 80, kenako idayambitsidwa ndi kampani ya 3M kuti iwonjezere kutumiza kwa fluorine elastomer PPA…… pang'onopang'ono amakhala ndi udindo wofunikira kwambiri pakukonza mafilimu, machubu, mapaipi, zingwe, ndi zina.

Malingaliro oletsa a PFAS (Perfluoro ndi Polyfluoroalkyl Substances), okonzedwa ndi akuluakulu a Denmark, Germany, Finland, Norway, ndi Sweden, adatumizidwa ku ECHA pa Januware 13, 2023, ndi cholinga chochepetsa kutulutsidwa kwa PFAS ku chilengedwe ndi kupanga zinthu ndi njira kukhala zotetezeka poletsa Perfluoroalkyl Substances (PFAS) ndi Polyfluoroalkyl Substances (PFAS) yomwe ili ndi atomu imodzi ya carbon perfluorinated (akuyerekezeredwa kukhala mamolekyu 10,000 onse), kuphatikiza ma fluoropolymers otchuka. (PFAS), kuphatikiza ma fluoropolymers otchuka. Mayiko omwe ali mamembala adzavotera chiletso mu 2025. Lingaliro la ku Ulaya, ngati silinasinthidwe, potsirizira pake lidzathetsa kugwiritsa ntchito ma fluoropolymers wamba monga PTFE ndi PVDF, kuletsa ntchito zambiri kupatulapo zochepa monga zipangizo zachipatala, zipangizo zoyankhulirana ndi chakudya, mafuta a mafuta, etc., ndi kukhudza kwambiri chilengedwe cha mndandanda wonse wa mafakitale.

Poyankha, SILIKE yawonetsa anjira yopanda fluorineku PPA yochokera ku Fluorine ——aPFAS-free polima processing aids (PPA). IziPPA MB yopanda Fluorine, PTFE-free additive ndi organically modified polysiloxane masterbatch yomwe imagwiritsa ntchito mphamvu yabwino yopangira mafuta a polysiloxanes ndi polarity ya magulu osinthidwa kuti asamuke ndikuchitapo kanthu pa zipangizo zopangira panthawi yokonza, zomwe zimapangitsa kuti zikhale zofanana ndi zomwe zili ndi silikoni zopanda Fluorine. zowonjezera mu extrusion wa mawaya ndi zingwe, chubu, ndi filimu, ndi pang'ono za zowonjezera bwino bwino utomoni fluidity ndi processability, komanso mafuta ndi pamwamba makhalidwe a pulasitiki kukhala extruded. Kuphatikizikako pang'ono kumatha kupititsa patsogolo kuyenda kwa utomoni, kusinthika, kukhathamiritsa, kudzoza, ndi zinthu zapamtunda panthawi yotulutsa pulasitiki, kupindulitsa makasitomala a polima ndi dziko lapansi ndikuwonjezera kupanga ndi mtundu wazinthu.

SILIKE PPA MB wopanda Fluorine, PPA yopanda PFAS,ndiZopanda PTFEzowonjezera zimatha kulowa m'malo mwa fluorine PPA masterbatch, PFAS Polymer Process Additive, PPA MB, zinthu za PPA, fluoropolymer, Fluorine-based PPAs, m'mafakitale ambiri monga mafilimu apulasitiki, zingwe & mawaya, mapaipi ... etc.

Zowoneka bwino:

Kupititsa patsogolo pulasitiki processing fluidity ndi extrusion dzuwa;

kuchepetsa torque ndi zida kuvala;

Chepetsani kufa kwa drool ndikuwongolera zochitika zapakhungu la shark.

Lumikizanani ndi SILIKE ndikupeza yanuPTFE Alternative Additive Solutions!
