Application Uses
Fuel for Portable Stoves: Butane is commonly used as a fuel in portable stoves, especially for camping and outdoor activities due to its efficiency and ease of storage in canisters.
Fuel for Lighters: Butane is the primary fuel used in many disposable lighters, providing a reliable and easy-to-use source of ignition for everyday use.
Propellant in Aerosols: Butane is used as a propellant in various aerosol products, such as hairsprays, deodorants, and air fresheners, helping to release the product in a spray form.
Industrial Fuel: Butane is used as a fuel for industrial processes, including in refineries and manufacturing plants, due to its ability to produce a clean, high-energy flame.
Raw Material for Synthesis: Butane is utilized in the chemical industry as a raw material for producing other chemicals like butadiene and isobutene, essential for the manufacture of synthetic rubber and other polymers.
Blended with Propane: Butane is often mixed with propane to form liquefied petroleum gas (LPG), which is used in heating, cooking, and even as an alternative vehicle fuel.
Refrigerant in Cooling Systems: Butane is sometimes used as a refrigerant in refrigeration systems, particularly in smaller, domestic appliances like fridges and freezers due to its low environmental impact compared to other refrigerants.
