Informations produit

Productprofil:

PLEXIGLAS® Optical POQ66 is an amorphous thermoplastic molding compound based on polymethyl methacrylate (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.

Example:

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

Processing:

PLEXIGLAS® Optical POQ66 can be processed on extruders with conventional three-section screws for engineering themoplastics.

 

For manufacturing extruded lightguide panels, it is advisable to maintain processing temperatures at the lower end of the scale.

Physical Form / Packaging:

PLEXIGLAS® Optical POQ66 is supplied as uniform pellets in big bags. Other forms of packaging on request.
