Iindaba

I-PFAS-ehlala ibizwa ngokuba "ziikhemikhali zanaphakade" -ziphantsi kovavanyo olungazange lubonwe kwihlabathi. NgokuPakisha kunye nokuPakisha uLawulo lweNkunkuma ye-EU (PPWR, 2025) evala iPFAS kwipakethe yoqhagamshelwano lokutya ukuqala ngo-Agasti ka-2026, kunye neSicwangciso sokuSebenza se-EPA PFAS (2021-2024) eqinisa imida kuwo wonke amashishini, abavelisi be-extrusion baphantsi koxinzelelo lokutshintsha i-polypoly-based-PFAPP ezinye iindlela

Kutheni kuyimfuneko ukubasusa iPFAS kwi-polymer extrusion?

Izinto ze-Per- kunye ne-polyfluoroalkyl (PFAS), iqela leekhemikhali eziqhubekayo eziphazamisa i-endocrine, kwaye ezinxulumene nomhlaza, isifo se-thyroid, kunye nemiba yokuzala. I-PFAS isetyenzisiwe kushishino kunye neemveliso zabathengi ukusukela ngo-1940s. I-PFAS ikhona yonke indawo kwindalo ngenxa yokwakheka kweekhemikhali ezizinzileyo. Njengoko kuthiwa "iikhemikhali zanaphakade", zifunyenwe kumhlaba, emanzini, kunye nomoya.8 Ukongezelela, i-PFAS ifunyenwe kwiimveliso ezahlukeneyo (umzekelo, i-cookware engapheliyo, i-laphu-resistant-resistant, i-foams firefighting), ukutya, kunye namanzi okusela, okukhokelela ekuvezweni kwehlabathi jikelele jikelele (> 95%).
Ke, ungcoliseko lwePFAS lukhokelele kwimithetho engqongqo ekusebenziseni kwabo izongezo zepolymer extrusion. Kwifilim, umbhobho, kunye nabavelisi bentambo, iiPPA zemveli zibeka imingcipheko ekuthotyelweni kokuthotyelwa kunye nodumo lophawu.

Ngezantsi lutshintsho olukhethekileyo lolawulo kunye namanyathelo anegalelo kolu tshintsho, ngokusekelwe kulwazi olukhoyo:

1. Iintshukumo zoLawulo zeManyano yaseYurophu (EU):

• Isithintelo sePFAS esiCetywayo se-ECHA (2023): NgoFebruwari ka-2023, i-Arhente yeMichiza yaseYurophu (ECHA) iphakamise uthintelo olubanzi kwi-per- kunye ne-polyfluoroalkyl substances (PFAS) phantsi kolawulo lwe-REACH. Isindululo sijolise kuluhlu olubanzi lwePFAS, kubandakanya i-fluoropolymers esetyenziswa njenge-polymer processing aids (PPAs). Ngelixa ishishini le-fluoropolymer lifuna ukuxolelwa, isikhokelo solawulo sicacile: izithintelo ziqhutywa kukuzingisa kokusingqongileyo kunye nobungozi bempilo obunokubakho bePFAS. Injongo kukunciphisa ukwenziwa, ukusetyenziswa, kunye nokubekwa kwabo kwimarike, ngaloo ndlela kuphembelela imizi-mveliso ukuba yamkele ezinye iindlela ezingena-PFAS.

• IQhinga le-EU leMichiza loZinzo: Isicwangciso se-EU sithatha indlela ebanzi yokulawula imingcipheko yePFAS, ibeka phambili ukukhutshwa kwezinto ezinobungozi kunye nokukhuthaza uphuhliso lwezinye iindlela ezingena fluorine, kubandakanywa nezo ze-polymer processing. Oku kukhawulezise ukuqalwa kwezinto ezintsha kwiiPPA zasimahla zePFAS, ngakumbi ukuqinisekisa ukuthotyelwa konxibelelwano lokutya kunye nemigaqo yokupakishwa.

• I-European Union Packaging and Packaging Waste Regulation (PPWR) 2025: Ipapashwe kwi-European Official Journal ngoJanuwari 22, 2025, i-PPWR iquka ukuvalwa kokusetyenziswa kwe-PFAS ekupakishweni kokutya ukuqala ngo-Agasti 12, 2026. Ummiselo ujolise ekunciphiseni ukupakishwa kwempilo ye-PFAS ngokupakisha impembelelo yokusingqongileyo kunye ne-PFW izixhobo, kubandakanywa i-polymer processing aids esetyenziswa kwi-extrusion yefilimu yeplastiki. Ngaphaya koko, i-PPWR igxininisa iimfuno zokuphinda zisetyenziswe-indawo apho iiPPAs ezingenazo ii-PFAS zibonelela ngenzuzo ecacileyo-ngaloo ndlela ikhuthaza ngakumbi ukutshintshela kwizisombululo zokupakisha ezizinzileyo.

 2. Uphuhliso loLawulo lwase-United States

• ISicwangciso sokuSebenza se-EPA's PFAS (2021–2024): I-Arhente yoKhuseleko lokuSingqongileyo yase-US (EPA) iphumeze imilinganiselo emininzi ukulungisa ungcoliseko lwePFAS:

• Ukutyunjwa kwePFOA kunye nePFOS njengezinto ezinobungozi (ngo-Epreli 2024): Ngaphantsi kweMpendulo eBanzi yokusiNgqongileyo, iMbuyekezo, kunye noMthetho woButyala (i-Superfund), i-EPA ikhethe i-perfluorooctanoic acid (PFOA) kunye ne-perfluorooctanesulfonic acid (PFOS)-iikhompawundi eziphambili zePFAS ezisetyenziswa kwizinto ezinobungozi-njengezinto ezinobungozi. Oku kwandisa ukungafihli kunye noxanduva lokucoca kwaye kukhuthaza amashishini ukuba atshintshele kwezinye iindlela ezingezizo zePFAS.

• UMgangatho waManzi okuSela weSizwe (ngo-Epreli wama-2024): I-EPA yagqibezela umgangatho wokuqala wamanzi okusela onyanzeliswa ngokusemthethweni we-PFAS, ejolise ekunciphiseni ukuvezwa kwabantu abamalunga ne-100 lezigidi. Lo mmiselo ucinezela amashishini ngokungathanga ngqo ukuba aphelise iPFAS kwiinkqubo zokuvelisa, kubandakanya iiPPA, ukuthintela ukungcoliseka kwemithombo yamanzi.

• I-Toxics Release Inventory (TRI) Izongezo (ngoJanuwari 2024): I-EPA yongeza i-PFAS ezisixhenxe kwi-TRI phantsi koMthetho wokuGunyanyiswa koKhuseleko lweSizwe lowama-2020, olufuna ingxelo ngo-2024. Oku kwandisa uqwalaselo kwii-PFAS eziqulathe iiPPAs kwaye ikhuthaza ukwamkelwa kwe-PFAS-free.

• Izindululo zoMthetho woLondolozo noBuyiselo (RCRA) (ngoFebruwari ka-2024): I-EPA indulule imithetho yokongeza iiPFAS ezilithoba kuluhlu lweendawo ezinobungozi phantsi kwe-RCRA, ukuqinisa igunya lokucoca kunye nokutyhalela abavelisi kwizisombululo ezingena-PFAS.

• Izithintelo zeNqanaba loMbuso: Amazwe afana neMinnesota aphumeze ukuvalwa kweemveliso ezine-PFAS, ezifana ne-cookware, ebonisa ukuphazamiseka okubanzi kwizinto ezisekelwe kwi-PFAS, kuquka ii-PPA ezisetyenziswa kwizicelo zoqhagamshelwano lokutya. Amanye amazwe, kubandakanya iCalifornia, iMichigan, kunye neOhio, bakhankanye ukunqongophala kwentshukumo yomdibaniso njengomqhubi wemithetho ye-PFAS yenqanaba likarhulumente, ekhuthaza ngakumbi ukutshintshela kwiiPPA ezingenazo iPFAS.

3. Amanyathelo ehlabathi kunye naweNgingqi:

• Isakhelo esiLawulayo saseKhanada: ICanada iseke imimiselo eyomeleleyo yokunciphisa nokulawula imveliso yePFAS nokusetyenziswa, ephembelela abavelisi behlabathi ukuba bathathe indawo yeePPAs ezisekelwe kwiPFAS ngeendlela ezizezinye ezingenafluorine.

• INgqungquthela yaseStockholm: Ingxoxo yamazwe ngamazwe ngolawulo lwe-PFAS, ngakumbi kwi-perfluorooctanesulfonic acid (PFOS) kunye neekhompawundi ezinxulumeneyo, iqhubekile isithuba esingaphezu kweminyaka elishumi. Ngelixa ingengawo onke amazwe (umzekelo, iBrazil kunye neTshayina) athintele ngokupheleleyo iPFAS ethile, indlela yehlabathi eya kulawulo ixhasa ukwamkelwa kweePPAs ezingena-PFAS.

• I-3M's Phase-Out Commitment (2022): I-3M, umenzi omkhulu we-PFAS, ubhengeze ukuba iyakuyeka imveliso ye-PFAS ekupheleni kuka-2025, ibangele ukunyuka kwemfuno yee-PPA ezingezizo ze-PFAS ukuba zithathe indawo yoncedo olusekelwe kwi-fluoropolymer kumashishini afana nefilimu kunye nokukhutshwa kombhobho.

4. Ukuthotyelwa koQhagamshelwano lokutya:

Imigaqo evela kwi-US Food and Drug Administration (FDA) kunye ne-European Food Safety Authority (EFSA) igxininisa iiPPAs ezingenazo iPFAS kwizicelo zoqhagamshelwano lokutya.

5. Uxinzelelo lweMarike kunye noShishino

Ngaphaya kwezigunyaziso zolawulo, imfuno yabathengi yeemveliso ezilungele indalo kunye neenjongo zozinzo lweshishini zityhala abanini bebhrendi kunye nabavelisi ukuba bamkele iiPPAs ezingena-PFAS. Oku kubonakala ngakumbi kumzi-mveliso wokupakisha, apho izisombululo zasimahla zePFAS zifunwa ukupakishwa okuguquguqukayo, iifilimu ezivuthelweyo, kunye neefilimu eziphosiweyo ukuhlangabezana nolindelo lwentengiso kunye nokunqanda ukonakala kwegama.

Impendulo yoShishino: iiPPAs eziMahala zePFAS

Abathengisi abakhulu abongezo bepolymer abanjengoSilike, Clariant, Baerlocher, Ampacet, kunye neTosaf baphendule ngokuphuhlisa iiPPAs ezingenazo iiPFAS ezihambelana okanye ezigqithise ukusebenza kwezixhobo ezisekelwe kwi-fluoropolymer. Ezi zikhetho zinceda ukunciphisa i-melt fracture, i-die build-up, kunye noxinzelelo lwe-extrusion, ngelixa uqinisekisa ukuthotyelwa kwemimiselo yokutya kunye nokuxhasa iinjongo zokuzinza.

Umzekelo,I-Silike SILIMER Series ye-Polymer Extrusion Additives ibonelela ngePFAS-simahla, izisombululo ezingenafluorineukoyisa imingeni yokusetyenzwa. Yenzelwe ukuvuthelwa, ukuphoswa, kunye neefilimu ezininzi, iifayili, iintambo, iipayipi, i-masterbatch, i-compounding, kunye nokunye, inokuphucula ukusebenza koluhlu olubanzi lwee-pololefins, kubandakanywa kodwa kungaphelelanga kwi-mLLDPE, LLDPE, LDPE, HDPE, PP, kunye ne-polyolefins esetyenzisiweyo.
