Informations produit

Productprofil:

PLEXIGLAS® Resist zk5HC 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 zk5HC is characterized by the following special properties:

 

  • high break resistance and impact strength
  • best resistance to stress cracking of all impact-modified PLEXIGLAS® molding compounds.

Application:

Used for extruding and coextruding sheets and profiles.

Example:

extruded/coextruded sheets and profiles for automotive bodies and the sanitaryware sector (bathtubs and shower trays) or crystal-clear luminaire covers for industrial plants that come into contact with aggressive media.

Processing:

PLEXIGLAS® Resist zk5HC 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.
