Product Description
Product Profile:
PLEXIGLAS® Resist zk4BR is an amorphous, impact-modified thermoplastic molding compound (PMMA-I).

Typical properties of impact-modified
PLEXIGLAS® molding compounds are
  • excellent weather resistance
  • excellent transmission and clarity
  • brilliant appearance
  • the pleasant feel and sound of the moldings

PLEXIGLAS® Resist zk4BR is characterized by the following special properties:
  • high break resistance and impact strength
  • improved resistance to stress cracking
  • balanced property profile
  • AMECA listing.

Application:
Used for extruding and coextruding sheets and
profiles as well as for injection molding

Examples:
extruded and injection-molded luminaire, covers, extruded hollow profiles, writing, utensils such as stencils and fountain pens, ppliance housings, coextruded profiles for window frames, gutters, downspouts, and housewares such as cutlery handles, bowls, cookie jars.

Processing:
PLEXIGLAS® Resist zk4BR can be processed on machines with 3-zone general purpose screws for engineering thermoplastics.

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