Plexiglas zk5HF Evonik Rohm Acrylic, Polymethyl Methacrylate

Product Description

Product Profile:
PLEXIGLAS® Resist zk5HF 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 zk5HF is characterized by the following special properties:

high break resistance and impact strength

improved resistance to stress cracking

excellent flow.

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

Examples:
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® Rzk5HF 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 25 kg polyethylene bags or in 500 kg boxes with PE lining; other packaging on request.
