350μm PET Film for Motor Insulation

350μm PET Film for Motor Insulation from Jinlu Film is engineered for extreme long-term reliability in high-voltage stator coils and offshore wind applications. With a 31.3 kV breakdown voltage, it acts as an impenetrable electrical barrier, eliminating the need for excessive multi-layer wrapping. What makes this gauge truly stand out is its 198% MD elongation — at 350μm, the film remains incredibly pliable, allowing it to wrap tightly around sharp stator edges without stress-whitening or cracking.
