Specifications
Kapton® Type HN is a
tough, aromatic polyimide film, 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 poly-condensation
reaction between pyromellitic dianhydride and
4,4.diaminodiphenyl ether. Kapton® HN is
available in the following gauges: 30 (7.5 µm),
50 (12.7 µm), 100 (25.4 µm), 200 (50.8 µm), 300
(76.2 µm), and 500 (127 µm). Other gauges, such
as 75 (19.1 µm) and 400 (102 µm), are available
by special request.

is obtained for either the MD or TD
using the average of three
measurements in either direction
before and after conditioning. Prior
to measurement, the 8 1/2" x 11"
(216 mm x 279 mm) specimen is
conditioned by freely suspending it
for 2 hr** in an oven controlled to
400°C (752°F). |
