View DetailsFor standard industrial and electrical applications, our Polyimide Film HN series offers an industry-proven baseline. This high-performance polymer film maintains outstanding physical, chemical, and electrical properties over a wide temperature range. Highly resistant to radiation, chemical solvents, and mechanical wear, the HN series provides reliable dielectric barriers for wire and cable wrapping, traction motors, and flexible printed circuits (FPCs) that must endure harsh, continuous operation.
As electronic devices shrink, space and weight optimization become critical design constraints. Our Ultra Thin Polyimide Film is specially manufactured to deliver exceptional flexibility and high dielectric strength at microscopic thicknesses. This specialized thin film allows design engineers to construct high-density, multi-layer flexible circuits, micro-sensors, voice coils, and compact battery insulation systems without sacrificing thermal endurance or risking electrical breakdowns.
In high-power electronics and dense LED assemblies, efficient heat dissipation is vital for product longevity. Our Polyimide Film MT is a specialized, thermally conductive grade designed to bridge the gap between heat transfer and electrical insulation. By facilitating superior thermal conductivity while retaining robust dielectric properties, the MT series is widely utilized in power semiconductors, battery pack thermal interfaces, and thermal pads, protecting sensitive electronics from heat build-up.
We are committed to providing our customers with the best possible service, from initial consultation to final delivery and beyond.
Extensive inventory and efficient logistics ensure your orders arrive on time, every time.
Rigorous testing and inspection protocols guarantee the highest quality insulation materials.
Our dedicated team of experts is available around the clock to assist with any technical inquiries.
Polyimide Film HN is our standard, highly versatile grade optimized for general high-temperature electrical insulation, mechanical toughness, and chemical resistance. Polyimide Film MT is a specialized, thermally conductive grade containing filler materials designed to significantly improve heat dissipation. While both maintain excellent dielectric strength, the MT series is specifically selected for thermal management applications, such as heat sinks and power electronics.
Ultra Thin Polyimide Film is highly beneficial in miniaturized and lightweight applications, including flexible printed circuits (FPCs), miniature medical sensors, microelectronics, and advanced acoustic diaphragms. Its ultra-low thickness provides maximum flexibility and space savings while maintaining the robust thermal stability and electrical isolation characteristic of standard polyimide materials.
Yes. All of our polyimide films are engineered to operate continuously across an impressive temperature range. Under standard operating conditions, they maintain their mechanical integrity and dielectric properties in temperatures ranging from extremely low environments up to continuous exposures of 260°C, with temporary survival capacity for much higher transient temperature spikes during manufacturing processes like reflow soldering.
