DuPont Kapton HN Polyimide Film Tape Amber 50 ft

High-Temperature Polyimide Film

This DuPont Kapton HN tape is a non-adhesive polyimide film supplied in a continuous amber roll. It serves engineers and technicians who need reliable electrical insulation that withstands extreme heat during manufacturing or repair work. The film suits applications such as coil wrapping, circuit-board masking and high-temperature splicing where conventional tapes would fail.

Integration Into Assembly Workflows

The 50 ft roll feeds cleanly from standard dispensers and can be cut to custom lengths without a sticky residue contaminating components. Because the film carries no adhesive, it frees assemblers from cleaning solvents and prevents unwanted bonding on gold fingers, connectors or sensitive surfaces. It layers easily under clamps, fixtures or secondary insulation materials in tight build spaces.

Behaviour Under Sustained Thermal Load

The polyimide construction maintains dielectric strength and dimensional stability up to 750 degrees Fahrenheit, resisting embrittlement and degradation during prolonged exposure. Unlike adhesive-backed tapes that soften or carbonise, this film retains its mechanical integrity throughout extended bake-out cycles, reflow profiles or continuous-operation environments where temperatures remain elevated for hours.
