Two overlapping, transparent sheets are displayed against a plain, white background. The top sheet has a light yellow tint, while the bottom one is slightly lighter, appearing almost clear. The edges of both sheets are clean and sharp, reminiscent of innovative designs seen in LED technologies from the Netherlands.
A blue circle is filled with evenly spaced horizontal black lines, creating a striped pattern reminiscent of LED modules. The lines make the blue color appear as alternating light and dark blue horizontal stripes within the circle against a white background.

N003 – Electrical Insulation Film

Thermoplastic polyetherimide film

N003 electrical insulating film is a high-quality thermoplastic polyetherimide material.
