Product Description
Product Profile:
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.

Processing:
PLEXIGLAS® 7N can be processed on injection molding machines with 3-zone general purpose screws for engineering thermoplastics.

Physical Form / Packaging:
PLEXIGLAS® molding compounds are supplied as pellets of uniform size, packaged in 25kg polyethylene bags or in 500kg boxes with PE lining; other packaging on request.
