Dow ENGAGE 8180 Impact modifier

Dow ENGAGE™ 8180 is a low-density, high-performance ethylene-octene copolymer with excellent flow characteristics, providing superb impact properties when blended with PP and PE. It is widely used in TPO applications requiring superior low-temperature impact performance. It also offers high filler loading capacity and excellent electrical properties, and when cross-linked, delivers exceptional heat aging, compression set, and weather resistance.

Features Of Dow ENGAGE 8180 Impact modifier

  1. Low density & high flow: Density of only 0.863g/cm³ with excellent flow properties, enabling high-speed processing and reducing product weight.

  2. Superior impact performance: Significantly enhances the impact resistance of PP/PE blends, especially in low-temperature environments.

  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. Strong compliance: Meets EU 10/2011 and U.S. FDA food contact standards.

Typical Applications Of Dow ENGAGE 8180 Impact modifier

  1. TPO impact modification: Automotive bumpers and exterior panels, improving low-temperature crash resistance and durability.

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

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

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

  5. Polymer modification: Toughening PP/PE to improve impact resistance of appliance housings and electronic devices.
