Transparency of MBS-modified PVC products lower than expected
Problembeschreibung
Transparency of MBS-modified PVC products is lower than expected, with high haze
Ursachenanalyse
Refractive index matching deviation between MBS and PVC
Improper processing temperature causes MBS rubber core deformation and scattering
Excessive MBS addition affects transparency
Insufficient mixing, MBS particle aggregation
Influence of gel particles in the PVC resin itself
Lösung
Select MBS models with refractive index matching PVC
Control processing temperature to avoid rubber core deformation
Reasonably control MBS addition amount (8-15%)
Fully mix to ensure MBS dispersion
Select gel-free PVC resin
Wichtigste Erkenntnis
MBS-toughened PVC transparency needs refractive index matching and dispersion
