description Product Description
Used primarily as a solvent in various industrial applications due to its ability to dissolve oils, fats, and waxes. It is commonly employed in the production of polystyrene foam, where it acts as a blowing agent to create the foam's lightweight structure. In laboratories, it serves as a non-polar solvent for chemical reactions and extractions. Additionally, it is utilized in the manufacturing of low-temperature thermometers and as a fuel component in some portable stoves. Its high volatility makes it suitable for use in aerosol products and as a cleaning agent for removing grease and contaminants from machinery and electronic components.
