Polyimide Film
Polyimide film is a kind of most valuable high temperature resistant electrical insulation material. This material does not crack in liquid helium at －269℃, it can works normally at 260℃ for long term. After radiation of 5x10 - 9 rad by quick electronic, it still keep 90% strength. Good dielectric property, dielectric constant is around 3.4.
With these excellent performance, polyimide film is used in many field: As insulation of motors and cables, as backing material and coverlay for flexible printed circuit, as label material, as acoustics materials. Below lists some specified application of this kind of high temperature film:
printed circuit board label ( PCB label ), polyimide film label, wire marking, electrical film, flame retardant tag, electronic film, flexible printed circuits ( FPC ) coverlay, dielectric film, self extinguishing label, space age film, esd label, self extinguishing tag, radiation resistant film, cable marking, corona resistant film, weatherproof labels, speaker bobbin material, high temperature insulation, chemical resistant film, cable insulation, harsh environment bar code, harsh environment labels, industrial high temperature labels, industrial self adhesive labels, masking tape for custom paint, SMT markings, 2D barcodes, anti static label
Type: HN
- Polyimide film HN is pure polyimide film.
- Thickness gauge: 0.5mil (13µm) - 10mil (250µm)
- Width gauge: 500mm, 520mm, 610mm, 900mm, 914mm, 1000mm, 1040mm or others
Type: FN
Polyimide film FN is polyimide film HN coated with FEP fluorocarbon resin, it is heat sealable grade.
PI film FN SpecificationAbove table lists the common types of FN film available. Other combinations are available.
Type：CR
Polyimide film CR can withstand partial discharge which can cause breakdown of the insulation material.
Tipo: FCR
Polyimide film FCR is polyimide film CR coated with FEP fluorocarbon resin, can withstand corona discharge, as wire insulation it helps to reduce partial discharge
Type: VN
Polyimide film VN is the same polyimide film as Type HN film, but with good peel strength and superior dimensional stability at elevated temperatures. It can be used in flexible circuit board (FPC), voice coil and other special department which requires good peel strength, etc.
Thickness gauge: 1mil (25µm) - 7mil(175µm)
