There are Three types of YITAP® polyimide film are described in this bulletin:

• YITAP® Type HN, all-polyimide film, has been used successfully in applications at temperatures as low as -269°C (-452°F) and as high as 400°C (752°F). Type HN film can be laminated, metallized, punched, formed, or adhesive coated. It is available as 7.5 µm (0.3 mil), 12.5 µm (0.5 mil), 25 µm (1 mil), 50 µm (2 mil), 75 µm (3 mil), and 125 µm (5 mil) films.

• YITAP® Type HPP-ST, all-polyimide film with all of the properties of Type HN, plus superior dimensional stability and modified surface for better adhesion. Type HPP-ST is available as 12.5 µm (0.5 mil), 25 µm (1 mil), 50 µm (2 mil), 75 µm (3 mil), and 125 µm (5 mil) films.

• YITAP® Type FN, a Type HN film coated or laminated on one or both sides with FEP fluoropolymer resin, imparts heat sealability, provides a moisture barrier, and enhances chemical resistance. Type FN is available in a number of combinations of polyimide and FEP thicknesses

In addition to these three types of YITAP® PI film, films are available with the following attributes:

• Antistat

• Thermally conductive

• Polyimides for fine line circuitry

• Cryogenic insulation

• Corona resistant

• Pigmented for color

• Conformable

• Other films tailored to meet customers’needs
