Propylene Oxide

Name: Propylene Oxide
SKU: 0

Propylene Oxide (PO) is a crucial organic chemical raw material and intermediate with the chemical formula C₃H₆O. As one of the simplest cyclic ethers, it exhibits high reactivity and volatility. Primarily produced via chlorohydrin or co-oxidation processes from propylene, PO is a key precursor for polyether polyols, propylene glycol, and other derivatives. It finds extensive applications in polyurethane, automotive, construction, food, and various other industries.
