01 /Applications

Polymerisation Co-monomer

1-Octene is widely employed as a co-monomer in the production of linear low-density polyethylene (LLDPE) and high-density polyethylene (HDPE). Its incorporation into the polymer chain introduces short-chain branching, improving flexibility, tear strength, and stress-crack resistance of the final plastic.

Organic Synthesis Intermediate

As a versatile alkene, 1-octene serves as a key intermediate in the synthesis of a range of organic compounds. It is used in the production of detergents, plasticizers, lubricants, and flavour and fragrance chemicals through various chemical transformations.

Fine Chemical Production

This compound acts as a foundational building block for more complex organic molecules. Its reactive double bond allows for various addition and functionalisation reactions essential in the development of specialty chemicals for diverse industrial applications.
