SpectraFlair Bright Silver and Bright Silver HSA pigments are suitable for use with many
technologies used to manufacture and decorate plastic molded parts including:
• injectionmolding
• extrusionblowmolding
• filmextrusion
• in-molddecorating
• thermoforming
• calendering
• reactivein-moldcoating.
Polymer Systems
Pigment effects are most successful when used with clear resin polymer systems such as:
• polycarbonate(PC)
• polypropylene(PP)
• high-densitypolyethylene(HDPE)
• thermalpolyurethane(TPU)
• polyethyleneterephthalate(PET)
• acrylonitrilebutadienestyrene(ABS)
• styreneacrylonitrile(SAN)
• celluloseacetate(CA)
• naturalrubber
• nylon12.
Colorsaturationandcolortravelaregreatestwhenusingaclearresinincombinationwithasmooth,
high-glosspartfinish.HDPEandothertranslucentresinsarealsousable;however,theresulting

Application Methods
Masterbatchproductioniseffectivewhenusingtwin-screw,co-rotatingextrudersandBanbury
mixers.Ifcurrentlymoldingwithmicaor��aluminumflakepigments,considerthoseprocess
conditionsasreasonablestartingparametersforthispigment.
Aswithallflakepigments,flowlinesmustbeconsidered.Fornewtooldesigns,adjustgatelocation
inordertominimizeandconcealflowlines.Someprocessessuchasfilm-insertmoldingandin-mold

forafractionofthecostofpainting.
Loading
Theamountofpigmentrequiredtogenerateastrongcoloreffectdependsonmanyfactorsincluding:
• surfacegeometry
• useofresin
• wallthickness
• surfacegloss
• presenceandlevelofotherpigments.
Beginaddingpigmentatarateof0.2–0.5percentpigmentbyweight.Loadinglevelscanbeadjusted
toachieveadesiredlookandtoreducecost.Theamountofpigmentcanbefurtherreducedby
usingmulti-layerblowmoldingandsheetextrusiontechniques.JDSUrecommendsusingalight
