Material Notes:
Description: Engage® 8400 and Engage® 8407 polyolefin elastomers are ethylene-octene copolymers that offer excellent performance in durable injection molded industrial and consumer goods and compression molded gaskets. Engage® 8400 and Engage® 8407 provide high clarity in products requiring visual inspection and allows the use of hot runner molds to enhance production efficiency. In addition, their low density can help control resin and production costs, while reducing the weight of end products. Engage® 8400 and Engage® 8407 also provide good impact properties in blends with polypropylene (PP) and polyethylene (PE), especially in applications requiring high melt flow modifiers. Engage® 8407 is Engage® 8400 with a nominal loose talc coating. The talc is untreated with a 1micron particle size. The product form for Engage® 8400 and Engage® 8407 is free-flowing pellets.Information provided by manufacturer.This former DuPont Dow Elastomers product line is now produced by Dow Chemical.
