Product Texts

Productprofil:

PLEXIGLAS? 8N is an amorphous thermoplastic molding compound (PMMA).

Typical properties of PLEXIGLAS? molding compounds are:

  • good flow
  • high mechanical strength, surface hardness and abrasion resistance
  • high light transmission
  • very good weather resistance
  • free colorability due to crystal clarity

Special properties of PLEXIGLAS? 8N are:

  • optimum mechanical properties
  • maximum heat deflection temperature
  • good flow / melt viscosity
  • AMECA listing.

Application:

Used for injection molding optical and technical items.

Example:

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

Processing:

PLEXIGLAS? 8N 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.
