Epoxypropane (propylene oxide, PO) is a low-boiling, highly reactive epoxide and the gateway chemical to polyether polyols, propylene glycol and glycol ethers.
Supply and service. Propylene oxide from Dongying EastChem ships in 170 kg galvanized or blue steel drums — pressure-relief storage guidance provided. 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. Downstream customers combine PO supply with propylene glycol and our polyurethane-chain products. Contact our sales team for current specifications, pricing and delivery schedules.
