Ethylene is the most fundamental raw material in the petrochemical industry. It is a colorless, flammable gas with a slight sweet odor at room temperature. Featuring reliable chemical activity and stable reaction performance, it is the core source for polymer materials and fine chemicals. Known as the "Mother of Chemical Industry", ethylene has stable purity and controllable reaction characteristics, suitable for polymerization, oxidation, alkylation and other chemical reactions.
Ethylene has extremely wide industrial applications. It is mainly used to produce polyethylene, PVC, polystyrene and other plastic materials for packaging, pipes, home appliances and auto parts. It is also widely applied in the synthesis of ethylene oxide, glycol, acetaldehyde and other fine chemicals for daily chemicals, pharmaceuticals, textiles and new energy industries. In addition, it can be used as high-quality industrial fuel for factory heating and process gas supply.
