Dow ENGAGE 8100 Impact Modifier

Dow ENGAGE™ 8100 is a high-performance ethylene-octene copolymer with excellent flow characteristics, suitable for a wide range of general-purpose thermoplastic elastomer applications. It provides superb impact properties when blended with PP and PE, and offers high filler loading capacity and outstanding peroxide cure capability. When cross-linked, it delivers exceptional heat aging, compression set, and weather resistance, making it suitable for high-performance electrical insulation.

Features Of Dow ENGAGE 8100 Impact Modifier

  1. Excellent flow properties: High melt index enables high-speed injection molding and extrusion, improving production efficiency.

  2. Superior impact performance: Significantly enhances the impact resistance of PP/PE blends, reducing the risk of embrittlement.

  3. High filler loading capacity: Allows high-proportion filler addition to optimize formulation cost and performance.

  4. Cross-linkable: Supports peroxide, silane, or radiation cross-linking, greatly improving heat aging, compression set, and weather resistance after curing.

  5. Excellent electrical properties: Ideal for wire and cable insulation with high electrical performance requirements.

  6. Pellet form for easy blending: Good compatibility with other polymers, allowing flexible formulation adjustments.

Typical Applications Of Dow ENGAGE 8100 Impact Modifier

  1. Polymer modification: As a toughener for PP/PE, improving impact resistance of appliance housings and automotive trim.

  2. Wire & cable: Cable insulation and jacketing, ensuring long-term stability with excellent electrical properties and weather resistance.

  3. General-purpose thermoplastic elastomers: Seals and cushions, suitable for harsh environments such as high temperatures and outdoor use after cross-linking.

  4. High-fill composites: As a carrier resin for masterbatch production, reducing costs while maintaining elasticity.

  5. TPO products: Automotive bumpers and exterior panels, improving low-temperature crash resistance and durability.
