Product Description
Product Profile:
PLEXIGLAS® 7M is based on polymethyl methacrylate (PMMA).

Besides showing the familiar properties of PLEXIGLAS® 7H molding compounds, such as
  • excellent light transmission and brilliance
  • excellent weatherability
  • high mechanical strength, surface hardness and abrasion resistance.

PLEXIGLAS® 7M is special in that it
  • better flowing behavior,
  • AMECA listing.

Application:
PLEXIGLAS® 7M is particularly suitable for extruding profiles and panels for use in lighting engineering.

Examples:
lighting fixtures, displays and similar extruded items for technical purposes.

Processing:
PLEXIGLAS® 7M can be processed on extruders with 3-zone general purpose screws for thermoplastics.

Physical Form / Packaging:
PLEXIGLAS® molding compound is supplied as pellets of uniform size in two-ply, 25kg polyethylene bags; other packaging on request.
