Material Notes:
MDI backbone: ester.Shore 00 Hardness: 85Summary: Durethane F is chemically blown urethane closed cell foam. Mearthane can custom formulate Durethane F, varying the physical properties (coefficient of friction, abrasion resistance, hardness and density) to suit various application. The rebound can be formulated for resiliency or energy absorption.Applications: Applications for Durethane F include self-cleaning paper feed rollers, retard pads, conveyor belts, bumpers shock absorbers and timing 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.
