DuPont Kapton HN Electrical Tape Amber 1/2 in 33 3/8 yd

High-temperature polyimide tape

This DuPont Kapton HN tape uses a polyimide film that withstands continuous exposure up to 750 degrees Fahrenheit. The amber roll measures one-half inch wide and runs for 33 3/8 yards. It is supplied new and non-adhesive for insulation or masking tasks that demand thermal stability.

Sustained thermal performance

The film maintains its dielectric and mechanical properties at the rated maximum temperature of 750 degrees Fahrenheit without degrading. Because the tape carries no voltage rating, it serves as a high-temperature barrier rather than a primary electrical insulator under load. Continuous rolls allow long, uninterrupted wraps on harnesses or components.

Width and length constraints

The fixed half-inch width limits coverage on wide conductors, requiring multiple passes for broader surfaces. The 33 3/8-yard roll length sets a hard cap on total linear coverage per unit. Users needing wider tapes or adhesive backing must select a different product.
