Optical Grade Polycarbonate Film

What is Optical Grade Polycarbonate Film?

Optical grade polycarbonate film is a highly transparent plastic film made from premium polycarbonate resin, engineered for optical applications requiring superior clarity and low distortion.
It is known for its high light transmittance, excellent impact resistance, and low haze properties.
This film is ideal for use in lenses, displays, light guides, and high-precision electronic devices.

What are the key features of optical polycarbonate film?

Optical PC film offers several outstanding features:
• Exceptional clarity and light transmission (up to 89–91%)
• Optical-grade surface with minimal birefringence and distortion
• High impact strength, far exceeding glass and acrylic
• Excellent dimensional stability and low shrinkage
• Surface options include gloss/gloss, gloss/matte, or hard-coated finishes

What applications require optical grade polycarbonate film?

This film is widely used in:
• Touch panels and capacitive switch overlays
• LCD and OLED display windows
• Light diffusers and light guides in backlit systems
• Optical lenses and protective covers
• Automotive HUD displays and gauge panels
Its low birefringence and superior optical performance make it the material of choice for precision optics and electronics.

Is optical PC film scratch-resistant or hard-coated?

Optical polycarbonate films are available with optional hard-coated surfaces for scratch resistance and chemical durability.
These coatings extend the film’s life and maintain visual clarity even in high-contact environments.
Anti-glare, anti-reflective, and anti-fog coatings can also be applied upon request.

How does optical PC film compare to PET or PMMA film?

Compared to PET film, optical PC film provides better impact resistance and temperature tolerance.
While PMMA (acrylic) has higher light transmission, polycarbonate offers superior durability and optical flatness.
Its low warpage and stable optical axis make it more suitable for precision engineering applications.

What thicknesses and sizes are available?

Common thicknesses range from 0.125 mm to 1.5 mm, though custom gauges can be produced.
Standard sheet widths are 610 mm to 1220 mm, with lengths in rolls or cut sheets.
Sizes can be tailored based on project requirements and fabrication processes such as die cutting or thermoforming.

Can optical PC film be printed or coated?

Yes, the surface of optical grade polycarbonate film supports various printing methods including screen printing, UV printing, and digital printing.
It is also compatible with adhesive lamination, anti-UV treatment, and sputtering for optical coatings.
Proper surface treatment ensures excellent ink adhesion and durability.

Is optical grade polycarbonate film UV-stable?

Standard PC film tends to yellow over time with UV exposure.
However, optical grade variants can be UV-stabilized or coated to resist UV degradation.
UV-protected versions are ideal for outdoor or long-term light-exposed applications.

Is this film suitable for cleanroom and medical use?

Yes, optical PC film is often produced in cleanroom environments to meet the purity and particulate control needed for medical and electronic optics.
It is also available in grades compliant with FDA and ISO 10993 standards for biocompatibility, making it suitable for medical devices, diagnostic windows, and protective covers.

Can optical PC film be recycled?

Polycarbonate is a thermoplastic and is fully recyclable.
Used optical films can be collected and reprocessed, contributing to more sustainable manufacturing.
Many suppliers also offer eco-friendly, BPA-free, or RoHS-compliant grades for green applications.
