Product Family Description

  • Lightweight Alternative to Glass Windows
  • Excellent Thermal and Chemical Resistance
  • Higher Transmission than Similar Transparent Plastics

Clear Optical Cast Plastic Windows are a lightweight and durable option compared to a glass alternative. These windows have a high transmission and low haze, have 25 - 50 times greater abrasion resistance, and are resistant to all types of chemicals and solvents (acetone, acids, alkali and alcohols). Due to their construction, these windows are able to be drilled using a carbide bit for various mounting needs.  
Clear Optical Cast Plastic Windows are uncoated, and are available in circular, rectangular, and square options.
