Testo del prodotto

Productprofil:

PLEXIGLAS® Resist zk6HF 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 zk6HF is characterized by the following special properties:

 

  • excellent break resistance and impact strength
  • improved resistance to stress cracking
  • very good flow.

Application:

Used for injection molding as well as for extruding sheets and profiles.

Example:

applications involving thin walls and long flow paths, thin-walled components; items requiring accurate mold surface reproduction, such as very finely textured luminaire covers.

Processing:

PLEXIGLAS® Resist zk6HF can be processed on machines with 3-zone general purpose screws for engineering thermoplastics.

Physical Form / Packaging:

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