Material Notes:

Description: Engage® 8452 polyolefin elastomer is an ethyleneoctene copolymer that offers excellent toughness, softness, and optical properties. It has excellent compatibility with other polyolefins, allowing for efficient blending and coextrusion. Engage® 8452 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. The product form is free-flowing pellets.Information provided by manufacturer.This former DuPont Dow Elastomers product line is now produced by Dow Chemical.
