CLAREX Precision Sheet is an Optical Grade Cell-Cast Acrylic Sheet with a flat (gloss) surface.

  • Light Transmission of 92-94%, higher than glass material.
  • High molecular weight, greater than extrusion PMMA sheet and Injection molding PMMA.
  • 2H surface hardness.
  • No birefringence or double refraction, ideal for optical sensor cover application.
  • Available from 0.2mm thickness
  • Close tolerance and  uniform thickness.
  • Ultra smooth glass-like surface.
  • Excellent weather resistance.
  • Addition of Hard Coat increases surface hardness to 6-8H
  • Non-Glare surface texture can also be applied
  • Anti-Reflection Coating surface treatment also available for improved light transmission  
  • Many standard substrate colours available or colour matching also available.
  • Versatile substrate suitable for laser cutting, milling, printing, forming etc.
