Product Description
Product Profile:
PLEXIGLAS® 8H 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® 8H molding compound are:
  • optimum mechanical properties
  • increased heat deflection temperature
  • high melt strength
  • AMECA listing.

Application:
Used for extruding optical and technical profiles and sheets.

Examples:
sheets, tubes, multi-skin sheets, coextrusion of window profiles and similar applications

Processing:
PLEXIGLAS® 8H can be processed on extruders 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.
