Plexiglas df23 7H Evonik Rohm Acrylic, Polymethyl Methacrylate

Product Description

Product Profile:
PLEXIGLAS® Satinice df23 7H, based on PLEXIGLAS® 7H, is characterized by diffuse scattering of light.

Typical properties of PLEXIGLAS® molding compound are

good flow

high mechanical strength, surface hardness and mar resistance

very good weather resistance.

Special properties of PLEXIGLAS® Satinice df23 7H are

excellent lightdiffusion combined with excellent light transmission,

matte surfaces can be obtained by varying the extrusion parameters.

Application:
Used for extruding profiles and sheets for lighting engineering applications

Examples:
luminaire covers, displays, projection screens and similar applications

Processing:
PLEXIGLAS® Satinice df23 7H can be processed on extruders with 3-zone general purpose screws for engineering thermoplastics. The matte finish of profile surfaces depends very much on machine design (calibrating unit, polishing rolls) and cooling conditions. It can be enhanced by controlled temperature reduction.

Physical Form / Packaging:
PLEXIGLAS® Satinice df molding compounds are supplied as pellets of uniform size, packaged in 25kg polyethylene bags; other packaging on request.
