300μm PET Film for Motor Insulation
300μm PET Film for Motor Insulation from Jinlu Film pushes dielectric strength past the 30 kV mark, making it the ultimate barrier for megawatt-scale generators and heavy industrial motors. At this extreme gauge, thermal shrinkage drops to just 0.9% MD, ensuring the insulation holds its exact dimensions even when subjected to the intense heat of continuous heavy-duty operation. With a 197% MD elongation, the film remains remarkably flexible, allowing it to be folded and formed into thick, complex slot geometries without breaking.
