Black PI Light-Blocking Film

Product overview

Black PI light-blocking film is a black polyimide film with no adhesive on either side by default. It has a smooth, flat surface, uniform color and effective optical coverage. Reference thickness is 0.0125 mm, roll length 50 or 100 m and width is slit to order. Long-term service around 200-260°C combines electrical insulation, mechanical strength and dimensional stability, making it suitable for light shields, insulation layers, black tape carriers and high-temperature laminates.

Product features

• Strong black coverage, uniform color and a smooth surface block visible light and maintain a consistent appearance.
• Polyimide provides excellent electrical insulation and dielectric performance for motors, cables and electronics.
• Long-term heat resistance around 200-260°C with low risk of discoloration, softening or dimensional change.
• Also resists low temperature, radiation, process media and organic solvents in demanding environments.
• Non-toxic, opaque and non-adhesive on both sides by default; adhesive coating or lamination can be specified.
• Reference thickness 0.0125 mm, roll lengths 50 or 100 m and custom slit widths, sheets or profiles.
• Good mechanical strength and flexibility for wrapping, slitting, punching and insulation lamination.

Applications

• Motor-slot insulation, magnet-wire wrapping, cable wrapping and internal electrical insulation.
• Light shields and black isolation layers in displays, cameras, sensors and precision electronics.
• Speaker materials, black slip sheets, black tape carriers and components requiring low reflection.
• Insulation laminates in communications equipment, automotive electronics, instruments and high-temperature electrical structures.

Procurement notes

State thickness, width, roll length, opacity or light-transmission target, temperature, adhesive or surface treatment, quantity and packaging. For high-temperature insulation, coating, printing or lamination, also state continuous temperature, voltage, contacted media and downstream process. Confirm color, opacity, dielectric properties, temperature and dimensional stability before production.
