Ethylene Gas Supplier
UN1962 Ethylene, Compressed | UN1038 Ethylene, Refrigerated Liquid
Ethylene is a colorless, flammable gas with a faint, sweet, musty odor. Ethylene is compressed to high pressure but may also be present as a liquid, depending on cylinder pressure and ambient temperature. Ethylene may also be shipped as a cryogenic liquid at -154.8°F.
Gas Innovations is an ethylene gas supplier offering five purity grades in compressed and cryogenic form, supporting polymer producers, specialty gas distributors, electronics manufacturers, and industrial processors that require verified purity at volume.

Ethylene Gas: Properties and Classification
Ethylene (C₂H₄) is the highest-volume organic chemical produced worldwide and the foundational building block of the global polymer industry. With a molecular weight of 28.05, ethylene falls under U.S. D.O.T. Hazard Class 2.1 and carries the Flammable Gas label. Its flammability range is 2.7-36% in air.
Ethylene also holds the refrigerant designation R-1150.
The physical properties of ethylene shift considerably between presentations:
- Compressed ethylene has a specific volume of 13.7 cubic feet per pound at 70°F and a density of 0.0725 pounds per cubic foot at 1 atmosphere.
- As a refrigerated liquid at -154.8°F, that density climbs to 4.71 pounds per gallon.
Every Gas Innovations shipment includes Safety Data Sheets, Certificates of Conformance, and full product specifications for both presentations.
Five Ethylene Purity Grades
Gas Innovations supplies ethylene gas across five purity levels, each supported by documented Certificates of Conformance (COC) and Certificates of Analysis (COA), and is backed by rigorous analytical quality control.
All grades are available in 300 and 200 cylinder sizes, containing 37 lb and 30 lb, respectively, at a cylinder pressure of 1,200 psi with CGA 350 valve outlets.
CP Grade (99.5%)
CP Grade ethylene is suited for general industrial processing, chemical synthesis, and controlled atmosphere applications where standard commercial purity meets operational requirements.
Polymer-Grade (99.9%)
Polymer-grade ethylene is formulated for polyethylene and other polymer production, where catalyst poisons such as acetylene, carbon monoxide, and oxygen must be kept within tightly controlled limits to protect reactor performance and resin quality.
Grade 4.0 (99.99%)
Grade 4.0 ethylene supports demanding chemical production, specialty polymer work, and laboratory environments where impurity tolerances are more restrictive than polymer-grade specifications allow.
Grade 5.0 (99.999%)
Grade 5.0 ethylene meets the stringent specifications required for electronics fabrication, semiconductor processing, and calibration applications where trace contaminants affect process outcomes.
Grade 5.5 (99.9995%)
Grade 5.5 is our highest available ethylene grade, engineered for the most sensitive applications where parts-per-billion contaminant control determines product viability.
Ethylene Applications Across Polymer and Industrial Markets
Ethylene anchors more downstream chemistry than any other organic feedstock. As a bulk ethylene supplier, Gas Innovations supports clients across the following high-demand sectors.
- Polyethylene and Polymer Production: Ethylene is the monomer used to produce HDPE, LDPE, and LLDPE resins.
- Chemical Intermediates: Ethylene feeds the production of ethylene oxide, ethylene glycol, ethylene dichloride, vinyl chloride monomer, and styrene for downstream manufacturing.
- Cryogenic Refrigeration: Designated R-1150, ethylene serves as a refrigerant in cascade systems and LNG liquefaction trains operating at -100°F to -155°F.
- Controlled Atmosphere Ripening: Commercial produce operations use metered ethylene to trigger uniform ripening in bananas, tomatoes, citrus, and other climacteric crops.
- Electronics and Specialty Manufacturing: Ultra-high-purity ethylene supports semiconductor processing, calibration gas blending, and specialty chemical synthesis.
Frequently Asked Questions About Our Work as an Ethylene Supplier
It comes down to how much you use and what storage you have on site. Cylinders and tube trailers work well for moderate volumes and need no special storage equipment. Refrigerated liquid holds much more product per shipment, so freight costs drop for high-volume users. It does require insulated cryogenic storage. Our team can compare the two options based on your usage.
