Polypropylene Oxide (PPO) is a type of polymer made from the chemical compound propylene oxide. It is known for its flexibility, durability, and resistance to chemicals, making it useful in various applications, including adhesives, coatings, and foams. PPO can be produced in different molecular weights, which affects its properties and uses. PPO is often used in the production of surfactants and as a component in polyurethane foams. Its compatibility with other materials allows it to enhance the performance of products in industries such as automotive, construction, and consumer goods. Additionally, polypropylene is a related polymer that shares some characteristics with PPO.
