Kapton Polyimide Tape with Acrylic Adhesive

Overview

Polyimide Tape has superior dielectric strength, and resistance to high temperatures, chemicals, tears, punctures, and abrasion. It is an excellent choice for high-temperature masking and electrical insulation. Polyimide tape is naturally an amber color.

This polyimide tape is manufactured by coating a 1.0 mil thick polyimide film with an 1.5 mil thick acrylic adhesive. Acrylic adhesive can be removed cleanly, leaving no residue in high-temperature applications.

Shelf Life

The standard shelf life for polyimide with pressure-sensitive adhesive (PSA) is 2 years from the date of manufacture, when stored in room conditions with a temperature of 75°F and relative humidity of 50%.

Applications

Electrical Insulation

Polyimide tape is primarily used in electrical applications such as coil, capacitor, and battery pack lead insulation. It is also great for high-heat environments, such as consumer electronics.

Aerospace

Polyimide tape is used to insulate wiring on satellites, spacecraft, and launch vehicles because of its thermal insulation and radiation resistance properties. It is also used as wire and cable insulation on aircraft because of its high mechanical strength, dielectric, and thermal insulation properties.

High-Temperature Masking

Polyimide tape with acrylic adhesive is ideal for use in high-temperature applications up to 311°F/155°C. Its amber color ensures easy identification and alignment. The high dimensional and exceptional tensile strength of this polyimide tape allows it to break through cured paint without silvering or tearing. Common uses include masking parts for powder coating, masking edges of overlap seams, e-coating, electroplating, anodizing, and as a barrier of separation for dissimilar metals. It resists shrinking, curling, and edge lifting and removes with zero adhesive residue.
