Description

n-Butane is a highly versatile and fundamental hydrocarbon gas, widely recognized as a key building block in the petrochemical and energy industries. Its primary value lies in its excellent properties as a fuel and as a crucial feedstock for producing important chemicals like ethylene and butadiene. This product is essential for manufacturers in the fuel blending (LPG), polymer synthesis, and refrigerant sectors, where consistent quality and reliable supply are paramount for production efficiency.

Application

• Fuel Component: A major constituent of Liquefied Petroleum Gas (LPG) for heating, cooking, and automotive fuel.
• Chemical Feedstock: Critical raw material for steam cracking to produce ethylene and for the production of butadiene, a key monomer for synthetic rubber (e.g., SBR, polybutadiene).
• Refrigerant: Used as a component in refrigerant blends, valued for its low environmental impact (low GWP).
• Aerosol Propellant: Employed as a propellant in various aerosol products, including personal care items and industrial sprays.
• Blowing Agent: Used in the production of polystyrene and polyurethane foams.
• Solvent & Extraction: Acts as a solvent in certain extraction processes within the pharmaceutical and fragrance industries.

Quality Control

Our n-Butane is produced and handled under stringent quality management systems to ensure batch-to-batch consistency and reliability. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as purity, hydrocarbon composition, and impurity levels. Our quality commitment aligns with global industrial standards, and specifications can be tailored to meet specific customer requirements for applications ranging from fuel to high-purity chemical synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store and handle in accordance with all local and international regulations for flammable gases. Containers must be kept in a cool, well-ventilated area away from heat, sparks, open flames, and other ignition sources. Due to its highly volatile and gaseous nature, ensure pressure relief devices are functional and systems are leak-proof.
