Lwm txoj kev daws teeb meem rau PPA raws li PFAS txwv

PPA (Polymer Processing Additive) uas yog fluoropolymer processing aids, yog fluoropolymer polymer-raws li cov qauv ntawm cov khoom siv polymer, los txhim kho cov kev ua haujlwm ntawm cov polymer, tshem tawm cov yaj tawg, daws qhov tuag buildup, txhim kho sharkskin, thiab lwm yam. Nws yog thawj zaug tsim los ntawm DuPont hauv xyoo 1961 thiab muab tso rau hauv kev ua lag luam hauv 80s, thiab tom qab ntawd pib los ntawm 3M lub tuam txhab los nthuav tawm cov khoom lag luam fluorine elastomer PPA …… Nrog rau kev nce qib ntawm thev naus laus zis, PPA fluorine-muaj cov khoom siv tau dav siv thiab maj mam tuav txoj haujlwm tseem ceeb hauv kev ua cov yeeb yaj kiab, raj, hoses, cables, thiab lwm yam.

PFAS (Perfluoro thiab Polyfluoroalkyl Substances) txwv kev txwv, npaj los ntawm cov tub ceev xwm ntawm Denmark, Lub Tebchaws Yelemees, Finland, Norway, thiab Sweden, tau xa mus rau ECHA thaum Lub Ib Hlis 13, 2023, nrog rau lub hom phiaj ntawm kev txo qis kev tso tawm PFAS rau hauv ib puag ncig thiab ua cov khoom thiab cov txheej txheem muaj kev nyab xeeb los ntawm kev txwv Perfluoroalkyl Tshuaj (PFAS) thiab Polyfluoroalkyl Tshuaj (PFAS) uas muaj tsawg kawg yog ib qho perfluorinated carbon atom (kwv yees li 10,000 molecules nyob rau hauv tag nrho), suav nrog fluoropolymer nrov. (PFAS), suav nrog cov fluoropolymer nrov. Cov tswvcuab hauv lub xeev yuav pov npav rau kev txwv txiav xyoo 2025. Cov lus pom zoo nyob sab Europe, yog tias tsis hloov pauv, thaum kawg yuav xaus kev siv cov fluoropolymers xws li PTFE thiab PVDF, txwv tsis pub siv feem ntau tsuas yog qee yam xws li cov khoom siv kho mob, khoom noj khoom haus, roj hlwb, thiab lwm yam, thiab cuam tshuam rau ecology ntawm tag nrho cov kev lag luam saw.

Hauv kev teb, SILIKE tau qhia iblwm txoj kev uas tsis muaj fluorinerau fluorine-raws li PPA ——aPFAS-free polymer processing aids (PPA). Qhov noTsis muaj fluorine PPA MB, PTFE-dawb additive yog ib qho organically hloov polysiloxane masterbatch uas siv qhov zoo tshaj plaws thawj lubrication nyhuv ntawm polysiloxanes thiab lub polarity ntawm cov hloov pab pawg mus rau migrating thiab ua yeeb yam ntawm cov khoom siv thaum lub sij hawm ua, uas ua rau tib yam kev ua tau zoo li Fluorine-dawb silicone-muaj. additive nyob rau hauv extrusion ntawm cov xov hlau thiab cables, tubing, thiab zaj duab xis, thiab ib tug me me ntawm cov additive no zoo pab txoj kev. resin fluidity thiab processability, nrog rau lubrication thiab nto yam ntxwv ntawm cov yas extruded. Qhov sib ntxiv ntawm ib qho me me tuaj yeem txhim kho cov dej ntws zoo, kev ua tiav, lubricity, thiab cov khoom nto thaum lub sij hawm yas extrusion, muaj txiaj ntsig zoo rau cov neeg siv khoom polymer thiab lub ntiaj teb thaum nce ntau lawm thiab cov khoom zoo.

SILIKE Fluorine-dawb PPA MB, PFAS-dawb PPA, thiabPTFE-dawbCov khoom siv ntxiv tuaj yeem hloov pauv fluorine PPA masterbatch, PFAS Polymer txheej txheem Additive, PPA MB, PPA cov khoom, fluoropolymer, Fluorine-based PPAs, hauv ntau qhov kev lag luam xws li yas zaj duab xis, cables & xov hlau, kav dej ... thiab lwm yam.

Tej kev ua yeeb yam:

Txhim kho cov yas ua fluidity thiab extrusion efficiency;

Txo lub zog torque thiab khoom siv;

Txo qhov tuag drool thiab txhim kho shark tawv phenomenon.
