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.
Low density & high flow: Density of only 0.863g/cm³ with excellent flow properties, enabling high-speed processing and reducing product weight.
Superior impact performance: Significantly enhances the impact resistance of PP/PE blends, especially in low-temperature environments.
High filler loading capacity: Allows high-proportion filler addition to optimize formulation cost and performance.
Cross-linkable: Supports peroxide, silane, or radiation cross-linking, greatly improving heat aging, compression set, and weather resistance after curing.
Excellent electrical properties: Ideal for wire and cable insulation with high electrical performance requirements.
Strong compliance: Meets EU 10/2011 and U.S. FDA food contact standards.
TPO impact modification: Automotive bumpers and exterior panels, improving low-temperature crash resistance and durability.
Wire & cable: Cable insulation and jacketing, ensuring long-term stability with excellent electrical properties and weather resistance.
High-fill composites: As a carrier resin for masterbatch production, reducing costs while maintaining elasticity.
General-purpose thermoplastic elastomers: Seals and cushions, suitable for harsh environments such as high temperatures and outdoor use after cross-linking.
Polymer modification: Toughening PP/PE to improve impact resistance of appliance housings and electronic devices.
