Brown Polyimide Sheet & Rod – High Temp, Anti-Static, Insulating Material

What is Brown Polyimide Sheet & Rod?

Brown polyimide sheet and rod are premium engineering plastics known for their extreme heat resistance, excellent electrical insulation, and anti-static properties. Made from high-performance polyimide (PI) material, these components are widely used in aerospace, electronics, semiconductor, and precision machinery industries where thermal stability and electrical safety are critical. Whether you are designing high-performance electrical insulation plates, anti-static support parts, or precision thermal components, our brown polyimide products deliver exceptional reliability and machinability.

Key Features and Advantages

Our brown polyimide sheet and rod provide outstanding performance in demanding environments. With a working temperature range of -200°C to 260°C (-328°F to 500°F), they maintain stability under thermal and electrical stress. The material’s low dielectric loss and surface resistivity in the anti-static range (~10⁵–10⁶ Ω) make it ideal for applications requiring both insulation and static dissipation. Available in diameters from 1.8mm to 60mm (0.07" to 2.36") and a standard length of 307mm (12.1"), this product is also suitable for CNC machining to meet your exact requirements.
