Lwm txoj kev daws teeb meem rau PPA nyob rau hauv PFAS kev txwv

PPA (Polymer Processing Additive) uas yog fluoropolymer ua cov khoom pab, yog cov qauv fluoropolymer polymer-raws li cov khoom pab ua polymer, los txhim kho kev ua haujlwm ntawm polymer, tshem tawm qhov tawg ntawm yaj, daws qhov pwm tsim, txhim kho cov tawv nqaij ntses, thiab lwm yam. Nws tau tsim thawj zaug los ntawm DuPont hauv xyoo 1961 thiab muab tso rau hauv kev ua lag luam hauv xyoo 1980, thiab tom qab ntawd tau tsim los ntawm 3M lub tuam txhab los nthuav kev xa tawm ntawm fluorine elastomer PPA…… Nrog rau kev nce qib tas mus li ntawm thev naus laus zis, PPA fluorine-muaj cov khoom pab ua tau siv dav thiab maj mam nyob hauv txoj haujlwm tseem ceeb heev hauv kev ua cov yeeb yaj kiab, raj, hoses, cables, thiab lwm yam teb.

Daim ntawv thov txwv tsis pub siv PFAS (Perfluoro thiab Polyfluoroalkyl Substances), uas cov tub ceev xwm ntawm Denmark, Lub Tebchaws Yelemees, Finland, Norway, thiab Sweden tau npaj tseg, tau xa mus rau ECHA thaum Lub Ib Hlis 13, 2023, nrog lub hom phiaj ntawm kev txo qhov kev tso tawm ntawm PFAS rau hauv ib puag ncig thiab ua kom cov khoom thiab cov txheej txheem muaj kev nyab xeeb dua los ntawm kev txwv tsis pub siv Perfluoroalkyl Substances (PFAS) thiab Polyfluoroalkyl Substances (PFAS) uas muaj tsawg kawg yog ib lub perfluorinated carbon atom (kwv yees li 10,000 molecules tag nrho), suav nrog cov fluoropolymers nrov (PFAS), suav nrog cov fluoropolymers nrov. Cov tswv cuab ntawm lub tebchaws yuav pov npav rau qhov kev txwv no hauv xyoo 2025. Daim ntawv thov European, 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 ob peb yam xws li cov khoom siv kho mob, cov ntaub ntawv sib cuag zaub mov, cov roj cell, thiab lwm yam, thiab cuam tshuam loj heev rau ecology ntawm tag nrho cov saw hlau kev lag luam.

Ua teb rau qhov no, SILIKE tau qhia txog ib qholwm txoj hauv kev uas tsis muaj fluorinerau Fluorine-based PPA ——aCov khoom siv ua cov polymer uas tsis muaj PFAS (PPA)Qhov noPPA MB uas tsis muaj fluorine, PTFE-free additive yog ib qho organically modified polysiloxane masterbatch uas siv cov nyhuv zoo heev ntawm polysiloxanes thiab polarity ntawm cov pab pawg hloov kho kom migrating thiab ua rau cov khoom siv ua haujlwm thaum lub sijhawm ua haujlwm, ua rau muaj kev ua tau zoo ib yam li Fluorine-free silicone-muaj additive hauv extrusion ntawm cov xov hlau thiab cables, tubing, thiab zaj duab xis, thiab me me ntawm cov additive no zoo txhim kho cov resin fluidity thiab processability, nrog rau lubrication thiab nto cov yam ntxwv ntawm cov yas raug extruded. Kev ntxiv me me tuaj yeem txhim kho cov resin ntws, processability, lubricity, thiab nto cov khoom thaum lub sijhawm yas extrusion, pab cov neeg siv khoom polymer thiab lub ntiaj teb thaum nce kev tsim khoom thiab cov khoom zoo.

SILIKE PPA MB uas tsis muaj Fluorine, PPA uas tsis muaj PFAS, thiabTsis muaj PTFECov khoom ntxiv tuaj yeem hloov tau fluorine PPA masterbatch, PFAS Polymer Process Additive, PPA MB, PPA cov khoom, fluoropolymer, Fluorine-based PPAs, hauv ntau yam lag luam xws li cov yas zaj duab xis, cables & xov hlau, kav dej ... thiab lwm yam.

Kev ua yeeb yam ib txwm muaj:

Txhim kho cov yas ua kua thiab kev ua haujlwm extrusion;

Txo qhov torque thiab cov khoom siv hnav;

Txo cov kua qaub ncaug tuag thiab txhim kho cov tawv nqaij ntses.
