PPS Thermal Insulation Film (220℃ Long-term Resistance)

PPS Thermal Insulation Film provides excellent heat resistance up to 220°C continuous operation, superior electrical insulation, chemical resistance, and dimensional stability for motors, transformers, EV batteries, and industrial electronics.

PPS Thermal Insulation Film (220°C Continuous Operating Temperature)

PPS Thermal Insulation Film is a high-performance polyphenylene sulfide (PPS) insulation film designed for demanding electrical and thermal applications. With continuous operating temperatures up to 220°C, it offers excellent dielectric strength, dimensional stability, chemical resistance, and mechanical durability. Compared with conventional PET insulation films, PPS film delivers superior thermal performance while maintaining excellent processability for die cutting, laminating, and precision converting. It is widely used in electric motors, transformers, EV battery systems, power electronics, industrial automation, and renewable energy equipment.
