DuPont KAPTON® Thin FilmsDuPont™ KAPTON® DuPont™ KAPTON® is a leader in the high performance films industry, offering over 40 years of diverse products, global technical support and customer service. DuPont has set a high standard in the polyimide film markets with its durability and performance in extreme temperature environments. KAPTON® has a unique combination of electrical, thermal, chemical and mechanical properties and retains these properties over a wide range of industrial environments and applications.
|DuPont™ KAPTON® HN general-purpose film has been used successfully in applications at temperatures as low as -269°C? (-452°F) and as high as 400°C (752°F). HN film can be laminated, metallized, punched, formed or adhesive coated. KAPTON® HN is the recommended choice for applications that require an all-polyimide film with an excellent balance of properties over a wide range of temperatures.

|DuPont™ KAPTON® HPP-ST is a two-sided, treated film that offers the same excellent balance of physical, chemical, and electrical properties over a wide temperature range offered by general purpose KAPTON® HN. Additionally, this high performance film has superior dimensional stability and excellent adhesion with most adhesive technologies. Adhesion data for HPP-ST can be referenced in the adhesion to KAPTON® technical bulletin.In applications where low shrinkage and superior adhesion are important, KAPTON® HPP-ST is the polyimide film of choice.

Ceramic board replacement
|DuPont™ KAPTON® XC polyimide films are electrically conductive, and are precisely loaded with conductive carbons to produce films with tightly controlled surface resistivities. XC film has proven performance in numerous satellite applications where it provides both thermal and anti-static control. XC film retains all the outstanding inertness, radiation and temperature resistance of other KAPTON® polyimide films, which make them ideal for use in space or other extreme environments.
||Satellite applicationsSpace or other extreme environments
|DuPont™ KAPTON® FN is a general purpose HN film that is coated or laminated on one or both sides with Teflon® FEP fluoropolymer. KAPTON® FN imparts heat sealability, provides a moisture barrier, and enhances chemical resistance. KAPTON® FN is recommended in applications that require a heat bondable film, or moisture and chemical resistance beyond the capabilities of uncoated KAPTON® films.
