| Uses | Important petrochemical raw materials, used in the production of polyether, propylene glycol, dimethyl carbonate, etc., surfactants, foaming agents, demulsifiers, beneficiation agents, etc. Among them, polyether polyol is an important raw material for the production of polyurethane foam, insulation materials, elastomers, adhesives and coatings. Various non-ionic surfactants are widely used in petroleum, chemical, pesticide, textile, daily chemical and other industries. At the same time, propylene oxide is also an important basic chemical raw material. | ||
