Description

Propylene CAS NO 115-07-1 is a fundamental, high-purity gaseous olefin and a critical petrochemical building block. Its high reactivity and versatile chemistry make it indispensable for synthesizing a vast array of industrial and consumer products. This essential monomer is primarily required by the polymer, chemical synthesis, and refining industries for the production of polypropylene, acrylonitrile, oxo-alcohols, and cumene.

Application

• Polymer Production: The primary feedstock for the manufacture of polypropylene (PP), one of the most widely used thermoplastic polymers.
• Chemical Synthesis: A key raw material for producing acrylonitrile (via ammoxidation), propylene oxide, cumene (for phenol/acetone), and oxo-alcohols.
• Refining & Fuel: Used in alkylation processes to produce high-octane gasoline blending components and as a liquefied petroleum gas (LPG) constituent.
• Specialty Chemicals: Serves as a precursor for acrylic acid, acrylate esters, and various solvents and plasticizers.
• Industrial Gas & Welding: Employed as a fuel gas in thermal cutting, brazing, and heating applications due to its high flame temperature.

Quality Control

Our propylene 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 purity, composition, and critical impurity levels (e.g., moisture, sulfur compounds, other hydrocarbons). Quality meets or exceeds typical industry specifications for polymer-grade and chemical-grade applications.

Storage

Preserve in a tightly closed container, protected from light. Store and handle as a compressed liquefied gas under its own vapor pressure in approved pressure vessels (cylinders, tube trailers, bulk tanks) in a cool, well-ventilated area away from heat, sparks, and open flames. Keep container tightly closed and sealed until ready for use. Due to its highly volatile and flammable nature, storage areas must comply with all local and national safety regulations for flammable gases.
