PIT3N | 3-mil Polyimide (Kapton) Film
- 3 mil polyimide film
- No adhesive
LINQTAPE™ PIT3N-Series is a high performance, flexible, hightemperature resistant polyimide film for many high temperature applications. Polyimide is preferred over polyester for many high temperature applications. These applications include but are not limited to semiconductor, smartcard, electronic, automotive and general manufacturing industries.
LINQTAPE™ PIT3N-Series provides an excellent balance of electrical, mechanical, thermal, and chemical properties over a wide range of temperatures. It can be used in applications that may see temperatures up to 400°C (752°F).
LINQTAPE™ PIT3N-Series comes in 33 meter (36 yard) length rolls of varying widths. The base polyimide film (backing) thickness is 2-mil (50.8 ± 2µm) thick. Polyimide films are available in a range of thicknesses, starting from 0.5 mil (12.7µm) thickness and up. Custom thicknesses are available upon request.
| Adhesive Layer |
A layer that is applied to one surface or both to bind items together and resist their separation

| Film Thickness |
Film thickness is the thickness of a backing film without taking into account any coatings or adhesive layers. It is measured in micron and the conversion factor to mil is 0.039.
| Total Thickness |
Total thickness is taking into account all the films, coatings, adhesives, release liners and special layers and is the maximum thickness of a film or tape.
| Dielectric Strength |
Dielectric strength is measured in kV per mm and is calculated by the Breakdown voltage divided by the thickness of the tested material.
Those two properties go hand in hand and while Breakdown voltage is always thickness dependent, dielectric strength is a general material property.
As an example, the dielectric strength of Polyimide is 236 kV/mm. If we place 1mm of Polyimide between two electrodes, it will act as an insulator until the voltage between the electrodes reaches 236 kV. At this point it will start acting as a good conductor, causing sparks, potential punctures and current flow.
| Volume Resistivity |
Volume resistivity, also called volume resistance, bulk resistance or bulk resistivity is a thickness dependent measurement of the resistivity of a material perpendicular to the plane of the surface.
| Temperature Resistance |
Temperature resistance is the maximum temperature that the material or product can withstand for a period of time.
The temperatures listed should be considered as guidelines for an operating temperature of about 30 minutes. Typically, the material can withstand much longer times at temperatures about 20°C lower and can withstand much higher temperatures for short, intermittent times.
| UL 94 Rating |
UL 94 Rating
Flammability rating classification.
It determines how fast a material burns or extinguishes once it is ignited.
HB: slow burning on a horizontal specimen; burning rate less than 76 mm/min for thickness less than 3 mm or burning stops before 100 mm
V-2: burning stops within 30 seconds on a vertical specimen; drips of flaming particles are allowed.
V-1: burning stops within 30 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed.
V-0: burning stops within 10 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed.
5VB: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may develop a hole.
5VA: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may not develop a hole
| RoHS Compliant |
