Description

Propane CAS NO 74-98-6 is a clean-burning, three-carbon alkane hydrocarbon widely recognized as a versatile fuel and critical industrial feedstock. Its high energy density and gaseous state at standard conditions make it an exceptionally efficient and portable energy source. This product is essential for industries ranging from residential and commercial heating to chemical manufacturing and transportation.

Application

• Fuel Source: Primary application as Liquefied Petroleum Gas (LPG) for residential, commercial, and industrial heating, cooking, and water heating.
• Transportation Fuel: Used as autogas (propane vehicle fuel) for fleets, buses, and forklifts, offering a lower-emission alternative to gasoline.
• Chemical Feedstock: A key raw material in petrochemical processes, notably in steam cracking for the production of ethylene and propylene.
• Refrigerant: Employed as a natural refrigerant (R-290) in commercial refrigeration and air conditioning systems due to its low environmental impact.
• Aerosol Propellant: Used as a propellant in various aerosol products, including paints, coatings, and insecticides.
• Metal Processing: Utilized as a fuel for cutting, brazing, and heat treatment in metalworking applications.
• Agricultural Use: Powers irrigation pumps, grain dryers, and provides heat for greenhouses and livestock barns.

Quality Control

Our propane is produced and handled under stringent quality management protocols to ensure consistent purity and performance for industrial and commercial applications. We adhere to relevant industry specifications such as HD-5 propane standards and can provide material compliant with various global fuel-grade requirements. A Certificate of Analysis (COA) detailing key parameters like composition, vapor pressure, and impurity levels is available for every batch upon request.

Storage

Preserve in a tightly closed container, protected from light. Store and handle in approved, properly labeled pressure vessels (cylinders, tanks) designed for liquefied petroleum gas. Keep containers in a cool, well-ventilated area away from direct sunlight, heat sources, and oxidizing materials. Storage areas must comply with all local and national fire and safety regulations for flammable gases.
