Material Has Expanded Dissipation Properties Improved Durethane C material now offers an expanded range of electrostatic dissipation properties that eliminate damaging electrostatic discharges in electronic machines. The formulation can also be used for charge-management applications. It can be produced either as a machinable solid thermoset polyure-thane or as a foam. Material comes in bars, rods, tubes, sheets, and rollers. MPC
