Dow Engage® 8180 Polyolefin Elastomer
Categories:	Polymer; Thermoplastic; Elastomer, TPE; Thermoplastic Elastomer, Melt-Processible Rubber
Material Notes:	Description: Engage® 8180 polyolefin elastomer is a lower density, high performance ethylene-octene copolymer that has excellent flow characteristics and provides good impact properties in blends with polypropylene (PP) and polyethylene (PE). It is widely used in TPO applications where excellent flow temperature impact properties are desired. Engage® 8180 also provides high filler loading capability and excellent electrical properties. When cross-linked by peroxide, silane, or irradiation, it gives exceptional heat aging, compression set, and weather resistance properties. The product form is free-flowing pellets.
