Polyimide Tapes and Films

Polyimide Film, Polyimide Tape and Generic Kapton® Products

CAPLINQ is proud to be a supplier of its own LINQTAPE™ PIT-Series brand of high-performance, flexible, high-temperature 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.

High Temperature Resistant Polyimide Film

LINQTAPE™ PIT-Series polyimide films are generic versions of DuPont's Kapton® film. As such, they are very stable at high temperatures, have excellent 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 (25µm) and 5-mil (125µm) thick. 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 and then an adhesive layer is applied to it. The base material itself has the same high temperature resistance, and dielectric properties described above, but the adhesive type and properties plays an important role in the selection process of a polyimide tape.

For high temperature applications, silicone is the adhesive of choice for polyimide tapes because it has the highest temperature resistance and maintains its adhesion the most when exposed to higher temperatures. In applications where silicone can absolutely not be used, or in applications that require a higher room-temperature adhesion is needed, CAPLINQ offers an acrylic adhesive version of polyimide tape. The range of polyimide tapes we offer has grown over the years as customers requested anti-static versions of adhesives, adhesives that left no residue after removal or very thin layers of adhesive.

LINQTAPE™ PIT-Series polyimide tapes typically come in 33 meter (36 yard) length rolls of varying widths. See the tape below for the range of polyimide tapes we currently offer. Other widths, lengths, thicknesses or adhesive types may be available upon request.

Frequently Asked Questions

Frequently Asked Questions about Polyimide Tapes and Films

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.

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.

Compare all Polyimide Film or Polyimide Tapes

Polyimide film and tape vary widely in their composition and application. Polyimide tapes may have silicone or silicone-free or adhesive, whereas polyimide film has no adhesive. Polyimide film can be as thin as 0.5 mil or as thick as 5 mil. Polyimide tape can be single-sided or double-sided and may come with or without release liner. Our Polyimide Tape and Polyimide Film Selector tool can help you choose the right polyimide tape for your application.
