Black Matte PI Masking Film

Black Matte PI Masking Film is a high-performance polyimide masking film featuring a matte black surface with excellent heat resistance, low reflectivity, electrical insulation, and chemical stability. Designed for demanding industrial environments, it performs reliably under continuous temperatures up to 260°C while maintaining excellent dimensional stability. The film is widely used in semiconductor manufacturing, PCB and FPC processing, laser cutting, precision masking, electronics assembly, and high-temperature industrial applications. Custom thicknesses, widths, and roll lengths are available.

Black Matte PI Masking Film Manufacturer & Supplier

Black Matte PI Masking Film is manufactured from premium polyimide resin using advanced coating technology to create a high-performance masking film with a matte black surface. Compared with standard amber polyimide film, the matte finish significantly reduces light reflection, making it ideal for optical inspection systems, laser processing, semiconductor manufacturing, and precision electronic assembly.

The film combines outstanding thermal stability, excellent electrical insulation, superior mechanical strength, and exceptional chemical resistance. It remains dimensionally stable during repeated thermal cycles and provides reliable masking protection in demanding industrial environments.

As an experienced polyimide film manufacturer, we supply customized thicknesses, widths, roll lengths, and OEM solutions for global industrial customers.
