CLAREX Precision Thin Sheet 001
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.
- A variety of standard substrate colours or bespoke colour matching is available.
- Versatile substrate suitable for laser cutting, milling, printing, forming etc.
