Plexiglas? 7N

Polymethyl Methacrylate Acrylic
Product Description:

PLEXIGLAS? 7N is an amorphous thermoplastic molding compound (PMMA).

Typical properties of PLEXIGLAS? molding compounds are:

  • good flow

  • high mechanical strength, surface hardness and mar resistance

  • high light transmission

  • very good weather resistance

  • free colorability due to crystal clarity.


Special properties of PLEXIGLAS? 7N molding compound are:

  • very good mechanical properties

  • high heat deflection temperature

  • very good flow / melt viscosity

  • AMECA listing.


Application:
Used for injection molding optical and technical items.

Examples:
optical waveguides, luminaire covers, automotive lighting, instrument cluster covers, optical lenses, displays, etc.
