Dow ENGAGE™ 8452 is an ethylene-octene copolymer offering excellent toughness, softness, and optical properties. It exhibits exceptional compatibility with other polyolefins, enabling efficient blending and coextrusion. With excellent flow properties and efficient cross-linking via peroxide, silane, or irradiation, it delivers exceptional heat aging, compression set, and weather resistance after curing, making it an ideal choice for high-performance elastomer formulations.
Excellent optical properties: High clarity and gloss, suitable for transparent elastic products with strict appearance requirements.
Balanced toughness & softness: High tensile strength and elongation at break, ensuring durability and comfortable tactile experience.
Superior compatibility: Easily blends with PP/PE and other polyolefins, allowing flexible formulation adjustments.
Cross-linkable: Significantly improves heat aging, compression set, and weather resistance after curing, suitable for harsh working conditions.
Excellent flow properties: High melt index enables high-speed processing and increased production efficiency.
Transparent elastic products: High-transparency seals, cushions, and food packaging films, balancing aesthetics and performance.
Polyolefin blend modification: Blending with PP/PE to enhance the impact resistance and optical properties of composites.
High-performance elastomer formulations: Seals and cable jackets for outdoor and high-temperature applications, ensuring long-term stability after cross-linking.
Coextruded films and sheets: Elastic layers in multi-layer composite films to improve toughness and puncture resistance.
