Dow Engage® 8842 Polyolefin Elastomer
Categories: Polymer; Thermoplastic; Elastomer, TPE; Thermoplastic Elastomer, Melt-Processible Rubber

Material Notes: Description: Engage® 8842 polyolefin elastomer is an ultra-low density ethylene-octene copolymer with a nominal loose talc surface coating. The talc is untreated and has a nominal 1 µm particle size. This product offers the exceptional properties of an ultra-low density elastomer with the added potential of handling this polymer in pellet form. Engage® 8842 has excellent flow characteristics and provides good impact properties in blends with polypropylene (PP) and polyethylene (PE). It performs well in TPO applications where superior low temperature impact properties are desired. 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 33°C, most preferably below 29°C.
