What is Polycarbonate (PC) Board? Specifications and Industry Applications
Optical PC sheets are made of polycarbonate (PC), a tough thermoplastic engineering plastic also known as unbreakable glass. Optical-grade PC sheets have high light transmittance, extremely high impact resistance (not easily broken), and good dimensional stability, and are commonly used in electronic screen protection, optical lenses, LED lamp covers, and precision instrument panels.
Key Properties
- Optical Performance: Exceptional light transmission (typically 88–90% or higher), low birefringence, and minimal distortion.
- Mechanical Strength: Extremely high impact resistance (nearly unbreakable compared to glass), excellent dimensional stability.
- Surface & Durability: Naturally scratch-prone but dramatically improved with hard coatings (up to 8H hardness), AR (anti-reflective), AF (anti-fingerprint).
- Thermal & Chemical: Good temperature resistance (-40°C to +120°C range), resistance to many chemicals when coated.
- Processability: Easily precision machined, thermoformed, die-cut, or CNC-machined into complex custom shapes.
- Lightweight: Approximately half the weight of glass, reducing overall device weight.
