ENGAGE™ 8450 is an ethylene-octene copolymer polyolefin elastomer from Dow, ideal for general-purpose thermoplastic elastomer applications. It features excellent polyolefin compatibility for blending and coextrusion, outstanding flow, and can be cured via peroxide, silane, or radiation to deliver exceptional heat aging, compression set, and weather resistance.
Supplied in pellet form, enabling automated production with precise dosing for improved processing efficiency
Excellent flow properties, supporting complex structural molding and high-speed extrusion/injection processes
Versatile crosslinking capability, curable via peroxide, silane, or radiation to adapt to diverse production scenarios
Enhanced post-crosslinking performance, providing exceptional heat aging, compression set, and weather resistance to extend product lifespan
Superior polyolefin compatibility, allowing efficient blending with PE, PP, etc., to expand material performance
General-purpose thermoplastic elastomer (TPE) products, including soft grips, seals, and cushions, balancing elasticity and durability
Cross-linked foam products, such as automotive shock absorbers, sound insulation materials, and shoe midsoles, improving light weight and rebound
Wire and cable insulation and outer sheaths, ensuring outdoor safety with excellent post-crosslinking heat resistance and weatherability
Industrial hoses and sealing strips, adapting to complex working conditions with long-term compression set resistance
Polymer blending modification, enhancing low-temperature toughness and impact resistance of PP/PE for appliance housings and automotive interiors
