500μm PET Film for Motor Insulation
500μm PET Film for Motor Insulation from Jinlu Film is the ultimate heavy-gauge barrier for the most demanding high-voltage power generation systems. Measured at 480μm (nominal 500μm), it delivers a massive 39.6 kV breakdown voltage, effectively replacing multiple layers of thinner films in massive generator slots. The standout feature at this extreme thickness is a 244% MD elongation — the highest in our range — allowing the film to be heavily folded and formed into complex geometries without any risk of mechanical failure.
