Description

Poly(Ethylene-Co-1-Octene) is a linear low-density polyethylene (LLDPE) copolymer produced by the copolymerization of ethylene with 1-octene comonomer. This material is engineered to deliver an optimal balance of processability, toughness, and flexibility, making it superior to conventional polyethylene in many demanding applications. It is a critical raw material for manufacturers in the packaging, automotive, and consumer goods industries seeking to enhance product performance and durability. The compound is supplied under CAS No. 26221-73-8.

Application

• Flexible and Stretch Film Production: Primary resin for manufacturing high-clarity, high-strength stretch wrap and pallet wrap films.
• Injection Molding: Used for producing durable consumer items, housewares, and industrial containers requiring excellent impact resistance.
• Blow Molding: Ideal for creating squeeze bottles, containers, and hollow articles with good environmental stress crack resistance (ESCR).
• Rotational Molding: Suitable for large, seamless tanks, playground equipment, and agricultural components.
• Wire & Cable Insulation: Provides excellent electrical properties and long-term thermal stability for insulation and jacketing.
• Polymer Modification: Acts as an impact modifier and compatibilizer in polymer blends and compounds.

Quality Control

Our Poly(Ethylene-Co-1-Octene) is manufactured under a stringent quality management system. Each batch is tested against key parameters including melt flow index (MFI), density, comonomer content, and mechanical properties to ensure batch-to-batch consistency and performance. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We adhere to relevant ISO standards and can support compliance requirements for food contact and specific regulatory frameworks upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C / 59-77°F). Keep away from heat sources, open flames, and strong oxidizing agents. For long-term storage, a nitrogen blanket is recommended to prevent oxidation.
