DuPont Kapton HN 966 Pack

This pack contains six pre-cut squares of yellow polyimide film tape with an acrylic adhesive. Each square measures 12 inches by 12 inches and has a thickness of 1 mil. The tape is designed for high-temperature electrical insulation and packaging tasks. It arrives new and ready for immediate use in a workshop or shipping environment.

Replaces standard masking or vinyl tapes

Standard tapes often fail when exposed to sustained heat or require clean removal after thermal cycling. This polyimide film maintains performance from 40 degrees F up to 300 degrees F. The upgrade is worth it when a job demands consistent dielectric strength and adhesive stability across that full range. It also eliminates the residue left by rubber-based adhesives after heating.

Behaviour under sustained thermal load

The acrylic adhesive and polyimide backing are rated for continuous operation at the maximum temperature of 300 degrees F. Unlike general-purpose tapes that soften or carbonise during long exposure, this construction resists embrittlement and maintains its bond. It does not carry a specific voltage rating, so it suits insulation wrapping rather than high-voltage termination. The six-square pack supports multiple maintenance cycles.

Questions about this item

How large are the pre-cut Kapton HN 966 squares?

Each piece measures 12 in by 12 in with a 1 mil polyimide film thickness, supplied in a pack of six.

What surface preparation ensures the acrylic adhesive bonds properly?

Clean the area to remove dust, oil or moisture, then apply firm pressure across the full 12 in square so the single-sided adhesive wets out evenly.

When should the tape be replaced in a high-temperature application?

Replace it once the operating environment exceeds 300 Degrees F or if the yellow film shows browning, embrittlement or loss of adhesion after repeated thermal cycles.
