Selecting Epoxy for Electric Vehicle Applications:
Featured Product from Epoxy Technology
This Webinar, now on demand, illustrates the challenges when selecting the best epoxy for electric vehicles' ("EV") unique applications. Since electric motors generate extreme heat at high current flow, thermally conductive, dielectric epoxy is crucial in the selection process. Raw material fillers, which enable conductive epoxy, will be discussed, as well as the test methods used to quantify their heat transfer. BULK thermal conductivity testing is compared and contrasted versus thin bond-line, triple-layer thermal resistance measurements.
When selecting epoxy for EV applications, regulatory compliance is commonly required. Many circuits and components mandate flame-resistant formulations per UL 94-VO. However, traditional flame retardant raw materials are banned and restricted through regulations such as ROHS and REACH.
Being a highly filled compound, the ideal thermal epoxy is compatible with mixers and agitators, metering pumps, and dispensers. In the selection process, the user-friendliness of the epoxy during industrial automation processes must be considered first. Epoxy properties like mix ratio, viscosity, thixotropy, particle size and cure will be illustrated.
Finally, reliability requirements are essential in the overall selection process. In addition to the high standards of automotive field conditions, EV applications are hostile, due to the chemicals and solvents inside batteries. Predicting reliability concludes the presentation.
