PC IR-Transmittance Grade (Infrared-Transmitting)

PC IR-Transmittance Grade – High-Clarity Infrared-Transmitting Polycarbonate for Sensors & Optical Devices

Infrared-transmitting polycarbonate grade with high IR transmittance and excellent thermal stability. Engineered for sensors, IR windows, remote-control covers and devices requiring consistent IR performance and mechanical resilience. The material offers chemical resistance and precise molding behavior to meet optical and dimensional tolerances. Custom transmittance specifications and UV-blocking co-formulations are available for mixed-spectrum applications.

Key Features

• High infrared transmittance
  Optimized to transmit IR wavelengths (typically 850–940 nm) for sensors, remotes, and optical communication.

• Visible-light blocking
  Provides a clean, tinted appearance (often black/purple/red) while allowing IR signals to pass through.

• Excellent impact resistance
  Retains PC’s toughness for protective covers and high-durability components.

• Heat-resistant performance
  Suitable for devices with continuous operation or outdoor exposure.

• Dimensional stability
  Low warpage and shrinkage; ideal for precision optical and electronic housings.

• Weather & UV resistance
  Performs reliably in outdoor or automotive environments.

• Easy processing
  Compatible with injection molding and precision optical molding.

Ideal For

• IR remote control windows & covers

• Sensor housings (PIR, IR, ToF, proximity sensors)

• Smart home devices and IoT optical modules

• Automotive ADAS, LiDAR, and remote sensing parts

• Surveillance cameras & optical filter panels

• Consumer electronics requiring IR transparency

Why Choose This Material

PC IR-Transmittance Grade combines optical performance and structural durability, enabling accurate IR signal transmission while protecting internal electronics. It’s the ideal material for manufacturers building smart devices, sensors, safety systems, and optical communication equipment that require both clarity for IR wavelengths and strong physical protection.
