PTFE emulsion tus nqi yog cuam tshuam los ntawm cov xwm txheej thoob plaws tag nrho cov saw hlau. Cov nqi qis (fluorite mining, R22 refrigerant quotas) teeb tsa tus nqi hauv pem teb. Downstream thov los ntawm lithium roj teeb binders yog tus tsav tsheb loj hlob. Cov khoom lag luam (tus nqi kev lag luam kev lag luam, kev saib xyuas cog) thiab cov khoom lag luam zoo (cov ntsiab lus ntawm cov khoom, qhov loj me, qib purity) tsim cov nqi tiers. Ib puag ncig cov cai (PFOA/PFAS txwv) nce nqi ua raws cai. Logistics (tsheb thauj mus los txias) ntxiv cov nuj nqis tseem ceeb. Nqe nqes ua raws li cov ntsiab lus tseem ceeb: fluorite / hydrofluoric acid nqi = pem teb; tshiab zog roj teeb xav tau = trend direction; kev khiav hauj lwm tus nqi thiab cov cai = lub sij hawm luv luv volatility ua rau.
