product description

Ethylene is the simplest alkene, with the chemical formula C₂H₄; it serves as both a core fundamental feedstock for the petrochemical industry and a naturally occurring ripening hormone in plants. This colorless gas is used industrially to manufacture various plastics and chemicals and agriculturally to accelerate fruit ripening, and its production volume is often regarded as a key indicator of a country's petrochemical industry capabilities.
