3-mil Polyimide (Kapton) Film No Adhesive

Product Description

CAPLINQ LINQFILM™ PIT3N Series films are 3-mil (75 micron) thick polyimide films – the generic equivalent of DuPont® Kapton™ HN film. LINQFILM™ PIT3N Series is a 3-mil (75 micron) thick, high performance, temperature resistant HN polyimide film that remains both electrically and mechanically stable across temperatures ranging from -269°C to 400°C (-452°F to 752°F). Polyimide film is widely used in applications requiring high electrical insulation and an excellent balance of thermal, mechanical, chemical and electrical properties.

CAPLINQ LINQFILM HN Polyimide Film is Versatile

As a base material, LINQFILM HN is extremely versatile as it can be die-cut, punched and thermoformed. It offers also excellent bondability and is the basis of many of our polyimide tape which apply either a silicone, rubber or acrylic adhesive layer. Is can also be further treated to make it thermally conductive, antistatic, corona resistant or metalized.

LINQFILM HN Polyimide is available as a stand-alone film (CAPLINQ LINQFILM PIT-N Series) in standard thicknesses of 0.5 mil (13 micron), 1 mil (25 micron), 2 mil (50 micron), 3 mil (75 micron) and 5 mil (125 micron). It is also available with specialty coatings applied to the film such as a conductive polymer to make it antistatic, a sputtered aluminum coating, corona resistant, with a FEP fluoropolymer coating, or as a black polyimide version. Custom thicknesses and/or coatings may be available, please ask for more details.

LINQFILM HN Polyimide is also available as a pressure sensitive tape by applying an adhesive layer to the HN polyimide film. The adhesive layer may be made of rubber, acrylic or silicone, and is most often applied 1.5 mil (37 micron) thick, except in our thinnest product offerings which offers adhesive thicknesses as low as 0.5mil (13 micron). The adhesive may also be applied on one or both sides of the film, and options are available to have it on a single or double-release, 3mil thick PET liner which makes it easier for handling or for the purpose of die-cut parts.

Product Applications

High temperature resistance, makes LINQFILM HN Polyimide ideal for 3D printing of ABS plastic. Being heat-sealable, LINQFILM HN polyimide films are used in applications that require polyimide films to be heat-bonded. It is extremely well suited, and extensively used for wrapping cable and magnet wire. A further list of applications includes, but is not limited to aircraft and spacecraft wiring, insulation tubing, slot insulation, fiber optics cable, heater circuits, automotive diaphragms and manifolds, high temperature splicing and other applications that can make use of the high temperature, electrically insulating properties of polyimide HN films.
