Product Texts

Productprofil:

PLEXIGLAS® Resist zk40 is an amorphous, impact-modified thermoplastic molding compound (PMMA-I).

 

Typical properties of impact-modified PLEXIGLAS® molding compounds are

 

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

 

PLEXIGLAS® Resist zk40 is characterized by the following special properties:

 

  • very good break resistance and impact strength
  • improved resistance to stress cracking
  • AMECA listing.

Application:

Used for injection molding. Profile extrusion or coextrusion are also possible.

Example:

lighting fixtures, writing and drawing utensils, domestic appliances and sanitaryware

Processing:

PLEXIGLAS® Resist zk40 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, packaged in 25kg polyethylene bags or 500kg boxes with PE lining; other packaging on request.
