High-Performance Polyimide Film (PI Film) Rolls
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.
