Polyimide Tapes and Films

Krayden supplies its own LINQTAPE™ PIT-Series brand of high-performance, flexible, high-temperature resistant polyimide film and tape, a generic equivalent to DuPont's Kapton® film. Polyimide is preferred over polyester for demanding high-temperature applications across semiconductor, smart card, electronic, automotive, and general manufacturing industries, where its thermal stability, dielectric insulation, and chemical resistance outperform standard polyester-based films and tapes.

LINQTAPE™ PIT-Series products are available as base film or as adhesive-backed tape, with adhesive chemistry (silicone or acrylic) selected based on the application's temperature range, adhesion requirements, and residue tolerance. All products are supplied in standard roll lengths and a range of widths and thicknesses, with custom specifications available on request.

Frequently Asked Questions about Polyimide Tapes

What is the difference between polyimide and Kapton?

DuPont were the original inventors of polyimide tape in the 1960\'s. They patented their product as Kapton tape. The patent for Kapton expired a long time ago, and the generic name version of the product is polyimide. DuPont continue to supply their Kapton tape under their brand name at a premium, but in reality, the material properties are exactly the same as polyimide.

Can I order a polyimide tape or film in a width other than what you have on your website?

Yes. Polyimide tapes and films are cut to width based on customer requests. For tapes the thinnest width we can reliably cut in 3mm (1/8 inch) wide, for film this is 6.5mm (1/4 inch) and for both tape and film the widest is the jumbo roll width of 508mm (20 inch). Otherwise, please ask us for any specific width you need. Minimum order quantities may apply.

What is the difference in operating temperature range for the different kinds of polyimide tape?

The operating temperature range of our polyimide films is between -269°C (-452°F) and 260°C (500°F). For the different types of tape this range is limited because of the specifications of the adhesive used. Our polyimide tapes with silicone adhesive have an operating temperature range between -73°C (-100°F) and 260°C (500°F). Our polyimide tapes with acrylic adhesive have an operating temperature range between -30°C (-22°F) and 175°C (347°F).

How can I apply your pressure sensitive tapes?

All our adhesives used for our polyimide tapes are pressure sensitive adhesives (PSA). This means they form a bond between two surfaces solely by surface contact, which is achieved by light external pressure to the adhesive or surfaces. PSA\'s are dry adhesives that can be applied at room temperature and require no activation with water, solvent or heat. Another advantage is that they adhere instantly saving time in production processes.

How can I remove pressure sensitive adhesive residue?

This will be completely application dependant. Since the adhesives are pressure sensitive, it will depend on the pressure you\'ll apply, the duration before peeling and of course the temperature and the type and smoothness of the surface. Hence it is almost impossible to say anything about the existence (or not) of residue.

IF there is residue, there are various ways to get rid of it with either heat (softening), cold (embrittlement), or chemical removal but we cannot recommend anything that might damage the rest of the package. As a rule of thumb, pressure sensitive adhesives do not harden to a cohesively strong solid. They are viscous liquids, and remain so when incorporated in an adhesive joint, so softening will (probably) be the easiest way.

Can I order a polyimide tape or film in a thickness other than what you have on your website?

Yes. Most of our polyimide tapes and films are available in a range of standard thicknesses; 12.7 micron (0.5 mil), 25.4 micron (1 mil), 50.8 micron (2 mil), 38.1 micron (3 mil), 127 micron (5 mil) and 254 micron (10 mil). The thinnest we can manufacture is 12.7 micron (1/2 mil) thick, thickest is 254 micron (10 mil) thick. Otherwise, please ask us for any specific thickness you need. Minimum order quantities may apply.

High-Temperature Resistant Polyimide Film

LINQTAPE™ PIT-Series polyimide films are generic versions of DuPont's Kapton® film. They are very stable at high temperatures, offer strong dielectric insulation properties, are mechanically solid without being too rigid, and can withstand a wide range of chemicals and solvents. LINQTAPE polyimide films can be used in applications that may see temperatures up to 260°C (500°F).

LINQTAPE™ PIT-Series polyimide films typically come in 33-meter (36-yard) length rolls of varying widths. The base polyimide film (backing) thickness range is between 1-mil (25 µm) and 5-mil (125 µm). Other widths, lengths, and thicknesses may be available upon request.

High-Temperature Resistant Polyimide Tape

LINQTAPE™ PIT-Series polyimide tapes start with a LINQTAPE polyimide film base, with an adhesive layer applied to it. The base material has the same high-temperature resistance and dielectric properties described above, but the adhesive type and properties play an important role in selecting the right polyimide tape for an application.

Silicone Adhesive

Best for: High-temperature applications requiring the strongest adhesion retention at elevated temperatures.

Why: Silicone is the adhesive of choice for high-temperature polyimide tape, as it offers the highest temperature resistance and maintains adhesion best under heat exposure.

Acrylic Adhesive

Best for: Applications requiring higher room-temperature adhesion, or where silicone can't be used.

Why: Acrylic offers stronger initial tack and bonding at ambient temperature, trading some high-temperature performance for room-temperature holding power.

The range of polyimide tapes offered has grown over the years to include anti-static adhesive versions, adhesives that leave no residue after removal, and very thin adhesive layers, based on customer application needs.

LINQTAPE™ PIT-Series polyimide tapes typically come in 33-meter (36-yard) length rolls of varying widths. Other widths, lengths, thicknesses, or adhesive types may be available upon request.
