Description

Poly(Ethylene-Co-1-Butene-Co-1-Hexene), Melt Index 3.5 is a linear low-density polyethylene (LLDPE) copolymer engineered for superior processability and mechanical performance. This specific melt index grade offers an optimal balance of flow characteristics and final product strength, making it a critical material for demanding extrusion and molding applications. It is essential for manufacturers in the packaging, film, and molded goods industries seeking reliable, high-performance polymer resins.

Application

• Cast and Blown Film Extrusion: Primary resin for producing high-clarity, high-strength stretch films, agricultural films, and heavy-duty shipping sacks.
• Injection Molding: Used for manufacturing durable household containers, industrial parts, and caps/closures requiring good impact resistance and environmental stress crack resistance (ESCR).
• Rotational Molding: Suitable for large, seamless containers, tanks, and playground equipment due to its excellent flow and uniform wall thickness distribution.
• Pipe and Cable Coating: Applied as a protective, flexible insulation and jacketing layer for wires and medium-density pipes.
• Compounding and Masterbatch: Serves as an excellent carrier resin for creating color and additive masterbatches.
• Flexible Packaging: Key component in multi-layer laminates for food and consumer product packaging, providing seal integrity and toughness.
