Material Notes:
Description: Engage® 8150 and Engage® 8157 polyolefin elastomers are ethylene-octene copolymers that have excellent flow characteristics and provide good impact properties in blends with polypropylene (PP) and polyethylene (PE). They are widely used in TPO applications where excellent low temperature impact properties are desired. Engage® 8150 and Engage® 8157 also provide high filler loading capability and outstanding peroxide cure capability. When crosslinked by peroxide, silane, or irradiation, they give exceptional heat aging, compression set, and weather resistance properties, and may be used to produce high performance electrical insulation. Engage® 8157 is Engage® 8150 with a nominal loose talc coating. The talc is untreated, with a 1 micron particle size. The product form is free-flowing pellets.Information provided by manufacturer.This former DuPont Dow Elastomers product line is now produced by Dow Chemical.
