产品说明
ProductProfile:
PLEXIGLAS®Satinice df22 zk6BR, based on PLEXIGLAS® Resist zk6BR, is an impactmodified molding compound characterized by diffuse scattering oflight.
Typicalproperties of impact modified PLEXIGLAS® molding compoundare
highbreak resistance and impact strength
﹒improvedresistance to stress cracking
﹒goodweather resistance
﹒highsurface hardness and mar resistance
﹒thepleasant feel and sound of the moldings.
PLEXIGLAS®Satinice df22 zk6BR is characterized by the following specialproperties:
﹒verygood lightdiffusion combined with excellent lighttransmission
﹒mattesurfaces can be obtained by varying the extrusionparameters.
Application:
Usedfor extruding profiles and sheets, but also for injection moldingitems for lighting engineering applications
Examples:
applicationsthat call for light diffusion combined with optimumtransmission
Processing:
PLEXIGLAS®Satinice df22 zk6BR can be processed on extruders with 3-zonegeneral purpose screws for engineering thermoplastics. The mattefinish of profile surfaces depends very much on machine design(calibrating unit, polishing rolls) and cooling conditions. It canbe enhanced by controlled temperature reduction.
PhysicalForm / Packaging:
PLEXIGLAS®Satinice df molding compounds are supplied as pellets of uniformsize, packaged in 25kg polyethylene bags; other packaging onrequest.
