Plexiglas? Optical POQ66

Polymethyl Methacrylate Acrylic
Product Description:

PLEXIGLAS? Optical POQ66 is an amorphous thermoplastic molding compound based on polymethylmethacrylate (PMMA).

In addition to the familiar properties of PLEXIGLAS? molding compounds, such as

  • excellent light transmission and brilliance,

  • very good weather resistance,

  • high mechanical strength, surface hardness and mar resistance,


PLEXIGLAS? Optical POQ66 is distinguished by its

  • guaranteed purity and clarity,

  • high luminous efficiency in medium to long light paths,

  • absolute colorlessness even in thick layers

  • UL registration RTI90 by (fi) 746C.


Application:
PLEXIGLAS? Optical POQ66 is suitable for manufacturing extruded sheets to meet stringent optical requirements.

Examples:
Medium to large extruded light guide (Light Guide Panel) for display applications.
