| ENGAGE™ 8450 Polyolefin Elastomer is an ethylene-octene copolymer that performs well in a wide range of thermoplastic elastomer applications. It has excellent compatibility with other polyolefins, allowing for efficient blending and coextrusion. ENGAGE 8450 provides excellent flow properties and is efficiently cross-linked by peroxide, silane, or irradiation. When cross-linked, it gives exceptional heat aging, compression set, and weather resistance properties. Main Characteristics: Pellet form Excellent flow characteristics Excellent compatibility with other olefins Peroxide, silane, and radiation curable Exceptional heat aging, compression set, and weather resistance when cured Applications: General purpose thermoplastic elastomers&& |
