1. Product Overview
Polyimide Film (PI Film) is a high-performance insulating material renowned for its exceptional thermal stability, chemical resistance, and mechanical strength. With a distinct amber-yellow appearance, this film maintains its superior physical and electrical properties across an extremely wide temperature range (typically from -269°C to +400°C).
As a versatile engineering plastic, it is the preferred substrate for flexible printed circuits and a critical component in various high-tech industries, including aerospace, automotive, and electronics. We offer high-grade Polyimide Film rolls available in various thicknesses and dimensions to meet your specific manufacturing needs.
2. Key Features
Extreme Temperature Resistance: Stable performance across a wide range from -269°C to +400°C.
Excellent Insulation: High dielectric strength makes it an outstanding electrical insulator.
Chemical & Solvent Resistance: Resists degradation from a wide range of chemicals.
Mechanical Toughness: Maintains dimensional stability and tensile strength under stress.
Customizable: Available in various thicknesses and slit widths to suit your application.
3. Applications
1 Flexible Printed Circuits (FPC) & Electronics
2 Electrical Insulation & Aerospace Components
3 Pressure-Sensitive Tape Base & Specialty Industrial Uses
4. Specifications & Customization
We understand that different applications require different specifications. We offer our Polyimide Film in a range of standard thicknesses and can customize the roll width to minimize waste in your production process.
