Propylene oxide is used as a precursor in the production of polyether polyols, which is utilized for making polyurethane plastics, polypropylene glycols, propylene glycol ethers and propylene carbonate. It is involved in the preparation of biological samples for electron microscopy. It plays a vital role in the removal of residual ethanol previously used for dehydration. Further, it is used in thermobaric weapons, and microbial fumigation. It is also used as solvents, and in the preparation of surfactants, lubricants and in oil demulsifiers.
