Machinable Durethane C offers range of electrostatic dissipation properties that eliminate damaging electrostatic discharges in electronic machines. Produced as solid thermoset polyurethane or as foam, formulation can also be used to supply specific charge density on surfaces. Material provides volume resistivity in solid urethane from E5-E10 ohm-cm at hardness of 5 Shore A to 70 Shore D and in open- or closed-cell foams from E7-E10 ohm-cm at hardness of 1A-90A.
