Vespel, Kapton
Ultra high-temp, radiation- and chemically-resistant polymer for space, electronics, and cleanroom uses.
Polyimide is a high-performance polymer known for outstanding thermal stability, chemical resistance, and mechanical strength. It maintains performance at temperatures above 250°C and resists radiation and solvents. Used in aerospace, electronics, and insulation applications, polyimide excels in extreme environments requiring durability, flexibility, and long-term reliability under thermal and mechanical stress.
