Types of KAPTON® Polyimide Film

DuPont makes several types of KAPTON® film. Types HN, FN, and VN are used most commonly.

Types H, F, and V are alternative, special versions of these standard types. The specifications in this bulletin apply to them as well. In addition to these three types of KAPTON®, films are available with the following attributes:

Data for these films are covered in separate product bulletins, which can be obtained from your DuPont KAPTON®representative.

Type HN Film

KAPTON® Type HN is a tough, aromatic polyimide laminate, exhibiting an excellent balance of physical, chemical, and electrical properties over a wide temperature range, particularly at unusually high temperatures. Chemically, its polyimide polymer makeup is the result of a polycondensation reaction between pyromellitic dianhydride and 4,4′ diaminodiphenyl ether. KAPTON® HN is available in the following gauges: 30 (7.5mm), 50 (12.7mm), 100(25.4mm), 200(50.8 mm), 300(76.2 mm), and 500 (127mm). Other gauges, such as 75 (19.1mm) and 400 (102mm), are available by special request.

Type FN Film

KAPTON® Type FN film is a heat sealable grade that retains the unique balance of properties of KAPTON® Type HN over a wide temperature range.  This is achieved by combining Type HN with DuPont Teflon® FEP fluorocarbon resin in a composite structure. Table 1 lists the common types of FN film available. Other combinations are available.
