Njengoko sonke sisazi, ixabiso le-fkm (fluoroelastomer) lenyuka kakhulu ngo-2021. Lafikelela kwixabiso eliphezulu ekupheleni kuka-2021. Wonke umntu wayecinga ukuba liza kuhla kunyaka omtsha. NgoFebruwari 2022, ixabiso le-fkm eluhlaza labonakala liphantsi kancinci. Ngelixa emva koko, imakethi inolwazi olutsha malunga nendlela amaxabiso ahamba ngayo. Isenokunganciphi kakhulu njengoko besiqikelele. Ngokwahlukileyo koko, ixabiso eliphezulu liza kuhlala ixesha elide. Kwaye imeko embi kukuba liza kunyuka kwakhona. Kutheni oku kuza kwenzeka?
Imfuno yePVDF enokusetyenziswa kwii-cathodes zebhetri ye-lithium iyanda kakhulu. Ngokweengxelo, imfuno yehlabathi yePVDF yee-cathodes zebhetri ye-lithium ngo-2021 yayiziitoni ezili-19000, kwaye ngo-2025, imfuno yehlabathi iya kuba malunga neetoni ezili-100 lamawaka! Iimfuno ezinkulu zibangela ukuba ixabiso lezinto eziluhlaza ezisezantsi i-R142 linyuke kakhulu. Ukuza kuthi ga namhlanje ixabiso le-R142b lisanyuka. I-R142b ikwayi-monomer ye-fluoroelastomer. I-general copolymer fluoroelastomer i-polymerized yi-VDF (vinylidene fluoride) kunye ne-HFP (hexafluoropropylene). Ngaphambi kukaSeptemba 2021, ixabiso le-copolymer raw gum limalunga ne-$8-$9/kg. Ukuza kuthi ga ngoDisemba 2021 ixabiso le-copolymer raw gum yi-$27~$28/kg! Iimpawu zamazwe ngamazwe ezifana neSolvay Daikin kunye neDupont zitshintsha ukugxila kwishishini elinenzuzo ngakumbi. Ngenxa yoko ukunqongophala kuyanda. Iimfuno eziphezulu kunye namaxabiso aqhubeka enyuka kubangela ukuba ixabiso le-fluoroelastomer liqhubeke linyuka kwaye aliyi kwehla ixesha elide.
Kutshanje omnye umthengisi omkhulu we-fkm raw gum uyekile ukubonelela nge-fkm. Kwaye omnye umthengisi sele ebhengeze ukunyuka kwamaxabiso. Ngenxa yokuqhambuka kwe-COVID eTshayina kutshanje, sicinga ukuba ixabiso eliphezulu liza kuhlala ixesha elide. Nceda unxibelelane neqela lethu lentengiso ukuze ufumane ixabiso elihlaziyiweyo kwaye ulungise izitokhwe zakho ngokufanelekileyo. Ndiyathemba ukuba singadlula kwiimeko ezinzima sibambene.
