Polyimide film is a good H grade insulating material. It is widely used for insulation purpose in electrical appliances which are used in special environment. To use the polyimide film means reducing volume and weight of the electrical appliances while retaining the same output or increase the capacity without increasing in frame size. It can also prolong the service life of the electrical appliances and increase their reliability. Its long-term working temperature is under 200 °C.

This Polyimide(PI) film F46(FEP) tape is abbreviated PI film F46 or PI film FEP, that is a general polyimide film that is coated or laminated on one or both sides with FEP Fluoropolymer, which imparts heat sealability, provides a moisture barrier, and enhances chemical resistance.

Polyimide tape is recommended in applications that require a heat bondable film, or moisture and chemical resistance beyond the capabilities of uncoated polyimide film.

Packing, Mark, Preservation and Transportation

1. The film should be provided in rolls and wound up to the pipe core, each roll is well packed and loaded with plastic bag to be placed into dry and clean box.

2. The each box packing should be marked with the type, product specification, size, lot number, gross weight, net weight, date of manufacture, name of the manufacturer and the product acceptances certificate is attached. At the same time the painting words of Damp-proof collision-proof etc.

3. The should be pressured in dry and clean room, the preservation period from the date of production is two years and can still be used when it is qualified in case of the preservation period is exceeded and checked according to standard.

4. During the preservation and transportation, damping and mechanical damage should be avoided.
