Ethylene (C₂H₄)

Ethylene, a colorless, slightly sweet-smelling hydrocarbon (C₂H₄), is the backbone of modern petrochemical industries. As the simplest alkene with a reactive carbon-carbon double bond, it exhibits high flammability (explosive range: 2.7–36% in air) and serves as a critical building block for synthetic chemistry. Used as feedstock for LLDPE/HDPE, epoxy ethane and ethanol production. Compatible with swing-reactor and high-pressure tubular processes. Our ethylene is supplied in high-purity grades (≥99.9% polymer-grade, ≥99.5% chemical-grade) via ISO-certified cylinders.
