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 ikulitse kutumiza kwa fluorine elastomer PPA……

Zoletsa za PFAS (Perfluoro ndi Polyfluoroalkyl Substances), zokonzedwa ndi akuluakulu aku Denmark, Germany, Finland, Norway, ndi Sweden, zidatumizidwa ku ECHA pa Januware 13, 2023, ndi cholinga chochepetsa kutulutsidwa kwa PFAS m'chilengedwe ndikupanga zinthu ndi njira kukhala zotetezeka poletsa Perfluoroalkyl Substances (ASfluoroalkyl Substances) ali ndi atomu imodzi ya carbon perfluorinated (akuyerekezeredwa kukhala mamolekyu 10,000 onse), kuphatikizapo 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, maselo amafuta, ndi zina zotero, ndipo zimakhudza kwambiri chilengedwe cha gulu lonse la 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 njira yabwino kwambiri yopangira mafuta a polysiloxanes ndi polarity ya magulu osinthidwa kuti asamuke ndikuchitapo kanthu pa zipangizo zogwirira ntchito panthawi yokonza, zomwe zimapangitsa kuti ntchito ikhale yofanana ndi yowonjezera ya Fluorine yopanda silikoni mu extrusion, chingwe ndi filimu yaing'ono, mawaya ndi filimu yaing'ono. bwino bwino utomoni fluidity ndi processability, komanso kondomu ndi pamwamba makhalidwe a mapulasitiki 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!
