Description

Poly(Ethylene-Co-1-Butene) is a linear low-density polyethylene (LLDPE) copolymer, engineered by incorporating 1-butene comonomer units into the ethylene polymer chain. This molecular architecture provides a superior balance of toughness, flexibility, and processability compared to conventional polyethylene resins. It is a critical material for manufacturers seeking enhanced durability and performance in films, molded parts, and wire & cable applications. Global industries from flexible packaging to automotive components rely on its consistent quality and reliable mechanical properties.

Application

• Flexible Packaging Films: Used in high-performance stretch films, shrink films, and heavy-duty sacks for superior puncture and tear resistance.
• Injection Molding: Ideal for producing durable household goods, industrial containers, and caps with excellent impact strength.
• Wire & Cable Insulation: Serves as a primary insulating and jacketing material due to its good electrical properties and environmental stress crack resistance (ESCR).
• Rotational Molding: Employed in manufacturing large, seamless tanks, playground equipment, and agricultural containers.
• Pipe & Conduit: Used in the production of corrosion-resistant pipes for fluid transport and protective conduits.
• Blow Molding: Suitable for bottles, fuel tanks, and other hollow articles requiring good stiffness and barrier properties.
• Compounding & Masterbatch: Acts as a base polymer for creating color or additive concentrates.

Quality Control

Our Poly(Ethylene-Co-1-Butene) is manufactured under stringent process controls to ensure batch-to-batch consistency and performance. Quality is verified against key parameters including melt flow index (MFI), density, comonomer content, and mechanical properties. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. Our quality management system is designed to meet the demands of global supply chains.

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). Keep away from heat sources and open flame. For long-term storage, keep under an inert atmosphere such as nitrogen to prevent oxidation.
