Ethyl methyl carbonate (EMC) is the performance co-solvent of lithium-ion electrolytes: it raises ionic conductivity and extends low-temperature discharge capability.
Supply and service. Ethyl methyl carbonate from Dongying EastChem ships in 200 kg galvanized or blue steel drums — IBC on request. Nineteen years of chemical manufacturing across three subsidiaries keeps bulk supply stable year-round: minimum order one 20′ container, samples dispatched in about 2 days, T/T or L/C payment, and a batch-specific COA with every shipment. Battery-material buyers source EMC together with DMC and DEC for one consolidated shipment. Contact our sales team for current specifications, pricing and delivery schedules.
