PI（Polyimide）

What is PI (Polyimide) ?

Polyimide (PI) is a family of high-performance polymers famous for outstanding heat resistance, often working continuously above 260°C (500°F). PIs also have great mechanical strength, wear resistance, good chemical stability, and act as excellent electrical insulators. They come in different types: some are thermosets (don't melt), while others are thermoplastics that can be melt-processed (like injection molding or extrusion). You can find PI as stock shapes (rods, plates for machining), thin flexible films (widely used in electronics for insulation and flexible circuits), or resins. Due to this combination of properties, PI is essential for tough jobs in aerospace, electronics, automotive, and various industrial sectors where extreme conditions demand superior material performance.

Thermoplastic PI (Polyimide)

Thermoplastic Polyimide (PI) offers exceptional high-temperature resistance combined with processing versatility similar to standard thermoplastics. It enables the creation of complex components via injection molding or extrusion while maintaining excellent mechanical strength and dimensional stability at elevated temperatures. Ideal for demanding applications requiring both performance and efficient manufacturing. Sourced for consistent quality and reliability in critical parts.

Reinforced PI (Polyimide)

Reinforced Polyimide (PI) leverages the inherent high-temperature performance of PI, enhanced with fillers like glass fiber, carbon fiber, or graphite. This significantly boosts mechanical properties such as strength, stiffness, and wear resistance. Ideal for structural components, bearings, or seals operating under demanding load and temperature conditions. Custom formulations are available to meet specific tribological or mechanical requirements.

PI Film (Polyimide Film)

PI Film (Polyimide Film) offers outstanding dielectric strength, thermal stability (-269°C to +400°C), and chemical resistance in a thin, flexible format. Widely utilized for high-performance electrical insulation, flexible printed circuits (FPCs), wire and cable wrapping, and protective layers in demanding electronics and aerospace applications. Provides reliable performance and durability where space, weight, and environmental resistance are critical.
