Kapton™ thermal insulation film for Fuji Prescale Film applications in high-temperature environments.



Kapton™ complementary film: Overview

As you may know, DuPont™ produces a wide range of high-quality plastic films, available for numerous application contexts. Tra questi, Among these, especially relevant for use alongside Fuji Prescale Film, Kapton™ Film are the polyimide films generally branded under the commercial name Kapton™. These films are also used in a broad spectrum of applications, from electrical to thermal insulation, across various sectors including electrical, electronic, and automotive industries. Additionally, within the Kapton™ product family, there are different types of films available, such as HN, FN, and HPP-ST, which are among the most commonly used. In this section, we will provide more detailed information about the HN type, which is marketed by Spare sas for use with Prescale Film.

Kapton™ complementary film: Usage Instructions

Simplified, the Kapton™ HN film serves as a flexible protective barrier that can be used to shield the Prescale Film during its use in high-temperature environments, such as those encountered in hot sealing processes or more generally where it is necessary to measure Kapton™ Film contact pressures in the presence of heat sources that cannot be deactivated during the Prescale testing. Cut the Kapton™ film so that its size and shape are slightly larger than the corresponding shape cut from the Prescale film roll. Then, place the Kapton™ film between the Prescale Film and the heat source(s). Considering that the maximum operational limit is 400°C, it is advisable to minimize the testing time to prevent excessive heat transfer through the Kapton™ film, which could potentially damage the Fuji Prescale Film during extended testing.
