Product Texts

Productprofil:

PLEXIGLAS® Resist zk5BR is an amorphous, impact-modified thermoplastic molding compound (PMMA-I).

 

Typical properties of impact-modified PLEXIGLAS® molding compounds are:

 

  • high weather resistance
  • excellent transmission and clarity
  • brilliant appearance
  • the pleasant feel and sound of the moldings.

 

PLEXIGLAS® Resist zk5BR 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 injection molding as well as for extruding and coextruding panels and profiles

Example:

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

Processing:

PLEXIGLAS® Resist zk5BR molding compound 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.
