Description

Ethene CAS NO 74-85-1 is a fundamental hydrocarbon and the simplest alkene, serving as a critical building block in the global petrochemical industry. Its high reactivity and gaseous nature make it an indispensable raw material for synthesizing a vast array of essential polymers and industrial chemicals. This product is vital for manufacturers in the plastics, packaging, automotive, and chemical synthesis sectors, where consistent quality and reliable supply are paramount for production efficiency.

Application

• Polymer Production: Primary feedstock for the manufacture of polyethylene (HDPE, LDPE, LLDPE), one of the world's most widely used plastics.
• Chemical Synthesis: Key intermediate in producing ethylene oxide, ethylene glycol (for antifreeze and polyester fibers), ethylbenzene (for styrene and polystyrene), and vinyl chloride (for PVC).
• Industrial Processes: Used as a ripening agent for fruits, a welding and cutting fuel gas, and in controlled atmosphere storage.
• Specialty Chemicals: Serves as a starting material for alcohols, aldehydes, and other fine chemicals through various catalytic reactions.
