Ethylene
Ethylene (CAS: 74-85-1; Formula: CH₂=CH₂) is a highly flammable gas with a molecular weight of 28.05 g/mol. It is a key building block in the petrochemical industry, primarily used as a monomer in the production of polyethylene. Ethylene also serves as a precursor for various organic chemicals and plays a role in fruit ripening and plant physiology. Tech Serve Solutions supplies Ethylene with a purity of ≥99.9%.

Polyethylene Production
Ethylene is the fundamental monomer for producing polyethylene, the world's most common plastic. This polymer finds extensive use in packaging, films, bottles, and containers.
Organic Synthesis Intermediate
It serves as a versatile starting material for synthesising a wide array of organic compounds. This includes ethylene oxide, vinyl chloride, and ethanol, which are vital industrial chemicals.
Specialty Gas Applications
In specialised applications, ethylene is used as a controlled atmosphere component, for instance, in fruit storage to manage ripening processes, and in scientific research.
