Motors/Stator Epoxy & Potting

EFI Polymers has developed a suite of epoxy encapsulating and potting products specifically for the motor manufacturing industry.  Currently, our material is being used by motor manufacturers all over the world to encapsulate thousands of stators every single day. Our materials for Motors/Coils/Power Supply are formulated with the following properties:

  • Underwriters Laboratories UL 1446 recognition: EFI has numerous systems to select from when customers are looking for a potting compound component of a UL 1446 recognized insulation system for use up to 180C (Class H) UL File # E 210549.

  • Low viscosity: allows our systems to penetrate and release air from even the tightest coil and slot windings, enabling many of our customers to eliminate varnishing and VPI practices from their manufacturing process.

  • Excellent Thermal Regulation: our materials have been formulated to withstand a wide range of temperatures, from Arctic Duty Motors to submersible Motors.

  • Outstanding Thermal Conductivity: our filled epoxy materials excel at transporting and dissipating heat from motors and other coil windings, a reduction in core temperature is always achieved.

  • Process friendly: our materials are designed to have mix ratios, viscosities, gel times that are friendly to process and automate.
