Thermobreak® RT-N is an innovative new insulation designed specifically for vehicles requiring electrically non-conductive materials. The new scrim material offers great strength and puncture resistance whilst also being non-conductive making it ideal for use in modern electric vehicles. Underneath this new scrim is the same high quality physically crosslinked polyolefin foam as used in Thermobreak® RT with excellent permeability and thermal conductivity performance.
