Overview
1-Octene is a high-purity linear alpha-olefin widely used as a comonomer in the production of linear low-density polyethylene (LLDPE). Copolymerization of ethylene with 1-octene yields LLDPE with superior mechanical properties, including high tensile strength, impact resistance, and environmental stress crack resistance. It also improves thermal stability, flexibility, and transparency of polyethylene products.

Applications

• LLDPE production: As a comonomer to enhance polymer performance.

• Plasticizers: Intermediate for the synthesis of specialty plasticizers.

• Surfactants: Raw material for the production of surfactants and detergents.

• Synthetic lubricants: Base fluid for high-performance synthetic oils and greases.

• Chromatography: Used as a reference standard in analytical chromatography.

• Chemical synthesis: Building block for various organic compounds.

Handling and Storage

• Store in a cool, dry, well-ventilated warehouse away from direct sunlight and heat sources.

• Keep containers tightly sealed to prevent evaporation and contamination.

• Separate from oxidizing agents and strong acids to avoid hazardous reactions.

• Fire prevention measures: use dry powder, CO₂, or foam extinguishers; water may be ineffective.

• Ground containers during transfer to prevent static discharge.

Packaging
Available in 1 L, 5 L, 20 L, and 200 L drums, as well as custom packaging upon request.

Quality Assurance
Each batch is tested for purity (GC), water content, and color to ensure consistent quality.
