Product Texts

Productprofil:

PLEXIGLAS® Optical POQ64 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,
  • good weather resistance,
  • high mechanical strength, surface hardness and mar resistance,

 

PLEXIGLAS® Optical POQ64 is distinguished by its

 

  • guaranteed purity and clarity,
  • very good flow properties,
  • optimised mold release behavior,
  • high luminous efficiency in medium to long light paths.

Application:

PLEXIGLAS® Optical POQ64 is excellently suited for the injection molding or injection-compression molding of technical components to meet stringent optical requirements.

Example:

Small to medium-sized injection-molded or injection compression-molded lightguide panels for display applications, lightguides.

Processing:

PLEXIGLAS® Optical POQ64 can be processed on injection molding machines with conventional three-section screws for engineering thermoplastics.

Physical Form / Packaging:

PLEXIGLAS® Optical POQ64 is supplied as uniform pellets in big-bags; other packaging on request.
