DuPont Polyimide Film · Critical Applications

Kapton® — high-performance insulation for critical applications.

DuPont polyimide film stable from −269°C to +400°C. The aerospace industry standard for flexible circuits, critical insulation, and high-performance electronics.

Overview

The high-performance film for the most demanding applications.

Kapton® is a polyimide film developed by DuPont. Its unique molecular structure gives it exceptional thermal, mechanical, and electrical performance across a temperature range few materials can match: from −269°C to +400°C.

Used in aerospace, defense, and high-performance electronics, Kapton® is the go-to choice for flexible circuits (FPC), high-temperature motor insulation, and components subjected to extreme environments. P&P Colorismédia laser-cuts it with precision for complex shapes and tight tolerances.

Properties

Technical characteristics of Kapton®.

Extreme Thermal Stability

Maintains its mechanical and electrical properties from −269°C to +400°C. No other plastic film offers a comparable temperature range.

High Dielectric Strength

150 to 300 kV/mm — among the best performance for an organic film. Reliable for insulating high-voltage conductors in compact environments.

Radiation Resistance

Very good resistance to ionizing radiation and UV. The standard for space applications exposed to intense radiant environments.

Retained Flexibility

Stays flexible and impact-resistant even at very low temperatures. Ideal for flexible circuits subjected to repeated folding.
