50μm PET Film for Motor Insulation
As a PET Film for Motor Insulation Manufacturer, Jinlu Film produces this 50μm hazy polyester film for slot liners, wedges, and die-cut insulation parts inside electric motors. The surface is deliberately hazy rather than glossy — that slight roughness gives better grip during insertion, so the film slides into the slot without slipping out of position. Breakdown voltage is 11.5 kV, and the film keeps 249/249 MPa tensile strength on both axes, staying flat and dimensionally stable through motor assembly.
