Properties of
Type FN Film
Heat Seal Strength
Film-to-Film Seals
The peel strength of heat seals between the coated and uncoated sides of one-side coated Kapton® or between the coated sides of both one- and two-side coated Kapton® is determined as follows.
Seals are made in a jaw sealer at 350°C (662°F), 20 psi (1.4 bar), with a 20-sec dwell time. After cooling, the seals are cut into 1. (25.4-mm) wide strips using a Thwing-Albert JDC sample cutter or its equivalent. The seal strength is measured with an Instron-type tensile tester. Seal strength is defined as the peak instantaneous strength occurring in each seal. Five specimen values are averaged.
The minimum peel strength between the coated sides of one- or two-side coated Kapton® film will be 700 g/in (2.7 N/cm), except for 120FN616 and 120FN616B, which will be 450 g/in (1.7 N/cm). The minimum peel strength between the coated and uncoated side of one-side coated Kapton® will be 450 g/in (1.7 N/cm).
Film-to-Copper Seals
The ability of FEP film to adhere to copper is measured using the same heat seal peel strength technique as described in "Film-to-Film Seals."
The peel strength is measured with the FEP side sealed to the untreated side of 1 mil (25.4 µm), 3/4 oz GT copper foil; it will be a minimum of 300 g/in (1.2 N/cm).
As-Received Strength (Cold Peel) of Bonds Between Kapton® Type HN and Layers made with Teflon® film.
The bond between the Kapton® Type HN and Teflon® fluorocarbon resin layers on all Type FN products except 120FN616 and 120FN616B will have a minimum peel strength of 225 g/in (0.87 N/cm), measured using an Instron-type tensile tester and a 180° peel.

Test Method Average of ten specimens tested per ASTM D-149-92. Flat sheets in air placed between 1/4" (6 mm) diameter brass electrodes with 1/32" (0.8 mm) edge radius subjected to 60 cycles AC voltage. Rise is 500 V/sec to the breakdown voltage. |

|
Test Method The percent shrinkage obtained for either the MD or TD by using the average of three measurements in either direction before and after conditioning. Temperature exposure 200°C ± 2°C (392°F ± 3.6°F) for 1 hr. Measurements must be made at the same temperature and humidity conditions before and after conditioning. To ensure sample/ambient equilibrium before and after conditioning, specimens should be exposed for 3 hr. |
General
Materials
Kapton® Type HN and Type VN films are polyimide polymers in the form of a film.
Kapton® Type FN film is a combination of Type HN film with FEP Teflon® fluorocarbon resin on one or both sides.
