Black Polyester Film Various Thickness Light Transmittance Full Blackout
product detail
Professional Black Polyester (PET) Film for Light Shielding & Insulation
Product Overview: Our Black Polyester Film is a high-performance PET film carbon-pigmented to provide superior opacity and aesthetic consistency. Designed for applications requiring total light blackout or deep black aesthetics, this film maintains the exceptional mechanical and thermal properties of standard polyester. It is an ideal solution for components that need to be both electronically insulated and visually shielded, offering a sleek, uniform finish in both matte and glossy variants.
Technical Specifications & Performance Highlights
-
Total Light Blocking (Full Blackout): Formulated with high-purity carbon black to achieve a high Optical Density (OD), effectively blocking 100% of visible light.
-
Superior Electrical Insulation: High dielectric strength makes it perfect for wrapping wires, insulating motors, and protecting circuit boards.
-
Exceptional Flatness & Stability: Low thermal shrinkage ensures the film remains flat and dimensionally accurate during high-temperature laminating or printing.
-
Uniform Surface Finish: Available in both High-Gloss Black for a mirror-like finish and Matte Black to reduce light reflection within optical devices.
-
Chemical & Heat Resistance: Withstands common solvents and oils while maintaining physical integrity at continuous operating temperatures up to 130°C - 150°C.
Application
Versatile Solutions for High-Tech Industries
-
Display & Backlight Units (BLU): Used as a light-shielding spacer or frame tape in smartphones, tablets, and TVs to prevent light leakage.
-
Electronic Insulation: Serving as an insulating layer in transformers, motors, and batteries, where black color is required for branding or identification.
-
Automotive Electronics: Protection and light-blocking for dashboard displays, sensors, and interior LED lighting components.
-
Membrane Switches & Labels: A durable base material for high-end control panels and durable identification labels.
-
Camera & Optical Instruments: Lining the interior of optical devices to absorb stray light and improve image contrast.
-
Solar Film & Construction: Used in specialty laminates where solar heat absorption or aesthetic concealment is required.
