Product Description
Product Profile:
PLEXIGLAS® Satinice df21 8N, based on PLEXIGLAS® 8N, 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 df21 8N are
  • good lightdiffusion combined with excellent light transmission.

Application:
Used for injection molding items for lighting engineering applications

Examples:
displays, backlight units

Processing:
PLEXIGLAS® Satinice df21 8N can be processed on injection molding machines with 3-zone general purpose screws for engineering thermoplastics.

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