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 optically clear, yet durable enough to withstand harsh environments. New plastic technology has produced windows with properties that can satisfy a variety of needs, but at half the weight of glass windows. Compared to similarly available transparent plastics, Thermoset ADC windows have the highest transmission and lowest haze, have at least 25 - 50 times greater abrasion resistance, and are resistant to all types of chemicals and solvents (acetone, acids, alkali and alcohols). The windows can also be easily drilled with high-speed carbide bits for all types of mounting.
