Ka Molao oa EU oa Packaging and Packaging Waste Regulation (PPWR, 2025) e thibelang PFAS ka har'a liphutheloana tsa lijo ho qala ka Phato 2026, le Leano la Ts'ebetso la US EPA PFAS (2021-2024) le tiisang meeli ho pholletsa le liindasteri, bahlahisi ba extrusion ba tlas'a khatello ea ho nka sebaka sa fluoropomer-based PFA-PFA mefuta e meng

Hobaneng ho hlokahala hotlosa PFAS ho polymer extrusion?

Per- and polyfluoroalkyl substances (PFAS), sehlopha sa lik'hemik'hale tse sa khaotseng tsa endocrine, tse amanang le mofetše, lefu la qoqotho le litaba tsa ho ba le bana. PFAS esale e sebelisoa indastering le lihlahisoa tsa bareki ho tloha ka bo-1940. PFAS e fumaneha hohle tikolohong ka lebaka la sebopeho sa bona sa lik'hemik'hale se tsitsitseng. Joalo ka seo ho thoeng ke "lik'hemik'hale tsa ka ho sa feleng", li fumanoe mobung, metsing le moeeng.8 Ho feta moo, PFAS e fumanoe lihlahisoa tse fapaneng (mohlala, li-cookware tse sa tsitsang, lesela le sa thibeleng matheba, li-foams tse timang mollo), lijo le metsi a nooang, e leng se lebisang ho pepesehela hoo e batlang e le hohle ho batho ba bangata (> 95%).
Kahoo, tšilafalo ea PFAS e lebisitse ho melao e thata ea tšebeliso ea bona ho li-additives tsa polymer extrusion. Bakeng sa baetsi ba lifilimi, liphaephe, le lithapo, li-PPA tsa setso li baka likotsi ho latela melao le botumo ba lebitso.

Ka tlase ke liphetoho tse ikhethileng tsa taolo le boikitlaetso bo tlatselletsang phetohong ena, ho ipapisitsoe le lintlha tse teng:

1. Liketso tsa Taolo tsa European Union (EU):

• Thibelo e sisintsweng ya PFAS ya ECHA (2023): Ka Hlakola 2023, European Chemicals Agency (ECHA) e ile ya sisinya hore ho be le thibelo e felletseng hodima per- and polyfluoroalkyl substances (PFAS) tlasa taolo ya REACH. Tlhahiso e shebile mefuta e mengata ea PFAS, ho kenyeletsoa li-fluoropolymers tse sebelisoang e le lithuso tsa ho sebetsa ka polymer (PPAs). Ha indasteri ea fluoropolymer e ntse e batla ho lokoloha, tataiso ea taolo e hlakile: lithibelo li tsamaisoa ke phehello ea tikoloho le likotsi tse ka bang teng tsa bophelo bo botle tsa PFAS. Sepheo ke ho fokotsa tlhahiso ea bona, ts'ebeliso le ho beoa ha bona 'marakeng, ka hona ho susumetsa liindasteri ho amohela mekhoa e meng e sa lefelloeng ea PFAS.

• Leano la EU la Lik'hemik'hale bakeng sa Moshoelella: Leano la EU le nka mokhoa o akaretsang oa ho laola likotsi tsa PFAS, ho etelletsa pele ho tsoa ha lintho tse kotsi le ho khothaletsa nts'etsopele ea mefuta e meng e se nang fluorine, ho kenyeletsoa le ea ho sebetsa ha polymer. Sena se potlakisitse boqapi ho li-PPA tse se nang PFAS, haholo ho netefatsa hore ho latela melaoana ea likhokahano tsa lijo le ho paka.

• European Union Packaging and Packaging Waste Regulation (PPWR) 2025: E phatlalalitsoe ho European Official Journal ka Pherekhong 22, 2025, PPWR e kenyelletsa thibelo ea tšebeliso ea PFAS ho pakang ha likhokahanyo tsa lijo ho qala ka Phato 12, 2026. lisebelisoa, ho kenyeletsoa lithuso tsa ho lokisa polymer tse sebelisoang ho extrusion ea filimi ea polasetiki. Ho feta moo, PPWR e totobatsa litlhoko tsa ho sebelisoa hape - sebaka seo li-PPA tse se nang PFAS li fanang ka monyetla o hlakileng - ka hona li khothaletsa phetoho e lebisang ho tharollo e tsitsitseng ea ho paka.

 2. Lintlafatso tsa Taolo ea United States

• Leano la Tshebetso la EPA la PFAS (2021–2024): Setsi sa Tshireletso ya Tikoloho sa US (EPA) se kentse tshebetsong mehato e mmalwa ho sebetsana le tshwaetso ya PFAS:

• Khetho ea PFOA le PFOS e le Lintho Tse Kotsi (April 2024): Tlas'a Molao o Felletseng oa Karabelo ea Tikoloho, Matšeliso, le Boikarabello (Superfund), EPA e khethileng perfluorooctanoic acid (PFOA) le perfluorooctanesulfonic acid (PFOS) - metsoako ea bohlokoa ea PFAS e sebelisoang linthong tse kotsi tsa PPA—e le lintho tse kotsi. Sena se eketsa pepeneneng le boikarabello ba ho hloekisa le ho khothaletsa liindasteri ho fetohela ho mekhoa e meng eo e seng ea PFAS.

• Maemo a Naha a Metsi a Nooang (April 2024): EPA e phethetse boemo ba pele ba metsi a nooang bo qobelloang ka molao bakeng sa PFAS, ka sepheo sa ho fokotsa ho pepeseha ha batho ba ka bang limilione tse 100. Taolo ena e hatella liindasteri ka tsela e sa tobang ho felisa PFAS mekhoeng ea tlhahiso, ho kenyeletsoa le li-PPA, ho thibela tšilafalo ea mehloli ea metsi.

• Toxics Release Inventory (TRI) Additions (Pherekhong 2024): EPA e kentse PFAS e supileng ho TRI tlasa Molao oa Tumello ea Ts'ireletso ea Naha ea 2020, e hlokang tlaleho bakeng sa 2024. Sena se eketsa tlhahlobo ho li-PPA tse nang le PFAS mme se khothaletsa ho amoheloa ha likhetho tse se nang PFAS.

• Resource Conservation and Recovery Act (RCRA) Proposals (February 2024): EPA e hlahisitse melao ea ho kenyelletsa PFAS tse robong lenaneng la libaka tse kotsi tse tlas'a RCRA, ho matlafatsa bolaoli ba tlhoekiso le ho sutumelletsa bahlahisi ho rarolla mathata a se nang PFAS.

• Lithibelo tsa Boemo ba Naha: Linaha tse kang Minnesota li kentse tšebetsong lithibelo ho lihlahisoa tse nang le PFAS, tse kang li-cookware, tse bontšang ho senyeha ho hoholo ha thepa e thehiloeng ho PFAS, ho kenyeletsa le li-PPA tse sebelisoang lits'ebetsong tsa lijo. Linaha tse ling, ho kenyeletsoa California, Michigan le Ohio, li qotsitse khaello ea ts'ebetso ea mmuso e le mokhanni oa melaoana ea boemo ba PFAS, e khothaletsang phetoho ea li-PPA tse se nang PFAS.

3. Mehato ea Lefatše le Lebatooa:

• Moralo oa Taolo oa Canada: Canada e thehile melaoana e matla ea ho fokotsa le ho laola tlhahiso le tšebeliso ea PFAS, e susumetsang baetsi ba lefats'e ho nkela li-PPA tse thehiloeng ho PFAS sebaka ka mekhoa e meng e se nang fluorine.

• Stockholm Convention: Lipuisano tsa machaba mabapi le taolo ea PFAS, haholo-holo bakeng sa perfluorooctanesulfonic acid (PFOS) le metsoako e amanang le eona, esale e tsoela pele ka lilemo tse fetang leshome. Leha e se linaha tsohle (mohlala, Brazil le China) tse thibelang li-PFAS tse itseng ka botlalo, mokhoa oa lefats'e oa taolo o ts'ehetsa ho amoheloa ha li-PPA tse se nang PFAS.

• Boitlamo ba 3M's Phase-Out (2022): 3M, moetsi e moholo oa PFAS, o phatlalalitse hore e tla emisa tlhahiso ea PFAS mafelong a 2025, e leng se tla etsa hore ho be le keketseho ea tlhokahalo ea li-PPA tseo e seng tsa PFAS ho nkela lithuso tse thehiloeng ho fluoropolymer indastering e kang filimi le extrusion ea lipeipi.

4. Tumellano ea ho Kopana le Lijo:

Melawana e tsoang ho US Food and Drug Administration (FDA) le European Food Safety Authority (EFSA) e totobatsa li-PPA tse se nang PFAS bakeng sa likopo tsa ho ikopanya le lijo.

5. Khatello ea 'Maraka & Indasteri

Ka ntle ho litaelo tsa taolo, tlhokahalo ea bareki ea lihlahisoa tse nang le tikoloho le lipakane tsa ts'ebetso ea khoebo li qobella beng ba lihlahisoa le bahlahisi ho amohela li-PPA tse se nang PFAS. Sena se bonahala haholo indastering ea ho paka, moo ho batloang litharollo tsa mahala tsa PFAS bakeng sa liphutheloana tse feto-fetohang, lifilimi tse bululetsoeng, le lifilimi tse hlahisoang ho fihlela litebello tsa mmaraka le ho qoba tšenyo ea botumo.

Karabelo ea indasteri: Li-PPA tsa Mahala tsa PFAS

Barekisi ba ka sehloohong ba tlatsetso ea polymer joalo ka Silike, Clariant, Baerlocher, Ampacet, le Tosaf ba arabile ka ho theha li-PPA tse se nang PFAS tse tsamaellanang kapa tse fetang ts'ebetso ea lithuso tse thehiloeng ho fluoropolymer. Mekhoa ena e meng e thusa ho fokotsa ho robeha ha ho qhibiliha, ho hakanngoa ha lefu, le khatello ea extrusion, ha ho ntse ho netefatsa hore ho latela melao ea puisano ea lijo le ho tšehetsa lipakane tsa ts'ebetso.

Ka mohlala,Silike SILIMER Series Polymer Extrusion Additives e fana ka PFAS mahala, litharollo tse se nang fluorineho hlola mathata a ho sebetsa. E etselitsoe bakeng sa lifilimi tse bululetsoeng, tse entsoeng le tse ngata, likhoele, likhoele, liphaephe, masterbatch, metsoako, le tse ling, e ka ntlafatsa ts'ebetso ea polyolefin e fapaneng, ho kenyeletsoa empa e sa felle feela ho mLLDPE, LLDPE, LDPE, HDPE, PP, le polyolefin e nchafalitsoeng.
