Plexiglas PMMA df22 7H

Plexiglas® PMMA df22 7H
聚甲基丙烯酸甲酯-丙烯酸
Evonik Industries AG
 
产品说明
Product Profile:
PLEXIGLAS® Satinice df22 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 df22 7H are
﹒very good 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 lighting applications
 
Processing:
PLEXIGLAS® Satinice df22 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.
