Axalta Adds New Impregnating Resin Voltatex 4224 to Energy Solutions Portfolio

This new, low-emission impregnating resin allows for the design of smaller and more efficient motors, and for the significant reduction of the operating temperatures of standard design motors. And Voltatex 4224 is manufactured using renewable raw materials.
 
Voltatex 4224 has a thermal conductivity that is more than double – 0.5 and 0.9 W/mK – compared to most standard impregnating resins. Available in three viscosity adjustments – low, medium and high– it can be processed with conventional impregnation technologies such as trickling, dripping and rolling. Voltatex 4224 is a styrene- and vinyl toluene-free impregnating resin, which means that emissions are reduced to a minimum in order to create a better working environment and limit flammability as well as emissions exposure.
 
“The technology we have used to formulate Voltatex 4224 has resulted in a resin that improves the heat transfer from the copper winding to the steel core causing less thermal stress in motors’ components, so that motors can run more efficiently and be smaller,” said Dr. Christoph Lomoschitz, global product manager for Axalta’s Energy Solutions business.
