Material Notes:
MDI backbone: ester.Shore 00 Hardness: 85Summary: Durethane M is a flexible, microcellular, open cell and closed cell urethane foam. Because it is mechanically mixed, the cell size is uniform. Durethane M is very economical, and has excellent resistance to compression set. It can be formulated to form an integral skin.Applications: The compression set resistance of Durethane M makes it an effective material for applications with repeated compression cycles, such as actuator pads on postal meters and idler belts.Conductivity: All Durethane elastomers can be formulated to be electrically conductive, for applications involving electrostatic dissipation (ESD). Mearthane's proprietary conductivity process does not comprise the material performance specification of the urethane.Information provided by Mearthane Products Corporation.
