- Adhesive-free heat sealing
- Continuous Temp: up to 300°C
- High peel strength to copper
Black Polyimide Film
Carbon-pigment matrix film providing absolute opacity (transmittance ≤ 0.1%) for camera modules, displays, and high-temp barcode labels.
- Opacity: Transmittance ≤ 0.1%
- Permanent pigment (won't fade)
- Wider roll defaults: 620 mm
ESD Polyimide Film
Special surface treatment delivering controlled static charge dissipation. Ideal for cleanroom microelectronics and wave solder masking.
- Controlled resistivity: 10⁵–10⁹ Ω
- Leaves zero residue on removal
- Protects microelectronics
Corona Resistant Film (CR)
Chemically modified with inorganic nano-fillers. Withstands partial discharge stress and voltage spikes in VFD motors and EV drivetrains.
- Corona Life: ≥ 80 hr at 3kV
- High dielectric: ≥ 200 MV/m
- FEP coated options (FCR/FCRF)
NHN Composite Film
Three-layer laminate featuring central HN polyimide film sandwiched between two layers of high-density Nomex non-woven insulation papers.
- High mechanical slot stiffness
- Breakdown Voltage: 8 – 10 kV
- Standard 914 mm slot rolls
Thermal Conductive (MT)
MT series film filled with thermally conductive ceramic particles. Combines heat spreading capabilities with full dielectric isolation for batteries.
- Conductivity: > 0.36 W/m·K
- Dielectric: ≥ 120 MV/m
- Crucial for EV battery dividers
Aluminized Polyimide Film
Sputtered vapor deposited aluminum on HN base film. Offers physical RF reflection and EMI shielding with one insulating side.
- Reflective PVD aluminum side

- Space MLI thermal blankets
Colourful PI Film
Red, Green, and transparent/clear films with color pigment cast directly within the matrix. Color remains stable without bleeding up to 400°C.
- Permanent color in matrix
- No bleeding or fading at 400°C
- Optically clear grade available
Voice Coil Former Film
Loudspeaker grade film with high dimensional heat stability and acoustic neutrality. Low moving mass, resistant to winding solvent varnishes.
- Zero former resonance
- Low moving mass density
- Resists winding varnish solvents
