Material Notes:
Description: Engage® 8207 polyolefin elastomer is a loose talc surface coated ethylene-octene copolymer. The talc is untreated and has a nominal 1µm particle size. This product offers the exceptional properties of Engage® 8200 with the added potential of handling these polymer pellets in rail cars. Engage® 8207 has excellent flow characteristics and performs well in a wide range of general purpose thermoplastic applications. It provides good impact properties in blends with polypropylene (PP) and polyethylene (PE). The talc addition significantly improves ability to handle the polymer, but severe blocking can occur if the material is stored under severe conditions (i.e., long duration, elevated temperatures, and/or high weight loadings). To minimize temperature effects, product should be stored at temperatures well below its melting point of 60°C.Information provided by manufacturer.This former DuPont Dow Elastomers product line is now produced by Dow Chemical.
