Plexiglas 8N Evonik Rohm Acrylic, Polymethyl Methacrylate

Product Description

Product Profile:
PLEXIGLAS® 8N is an amorphous thermoplastic molding compound (PMMA).

Typical properties of PLEXIGLAS® molding compounds are:

good flow

high mechanical strength, surface hardness and abrasion resistance

high light transmission

very good weather resistance

free colorability due to crystal clarity

Special properties of PLEXIGLAS® 8N are:

optimum mechanical properties

maximum heat deflection temperature

good flow / melt viscosity

AMECA listing.

Application:
Used for injection molding optical and technical items.

Examples:
optical waveguides, luminaire covers, automotive lighting, instrument cluster covers, optical lenses, displays, etc.

Processing:
PLEXIGLAS® 8N can be processed on injection molding machines with 3-zone general purpose screws for engineering thermoplastics.

Physical Form / Packaging:
PLEXIGLAS® molding compounds are supplied as pellets of uniform size, packaged in 25kg polyethylene bags or in 500kg boxes with PE lining; other packaging on request.
