硫酸钡BS60电子墨水

Barium Sulfate BS60for Electric Ink Item IndexBarium sulfate (by dry basis) ≥97.0%Volatile ≤0.3%Iron (Fe) PPm ≤10Whiteness ≥96.0Oil absorption 15 25g/100gPH value 6.5 9.0Fineness (Sieve residue of 325-mesh test sieve) ≤0.2%Mean grain diameter (D50) ≤0.60μm Electric conductivity ≤0.3ms/cm Features Special organic envelop treatment endows it with high whiteness, no impurities, narrow and uniform size distribution, outstanding dispersion, and very efficient pigment dispersion. Therefore, it can fully bear every colorant crystal around and uniformly extending and dispersing in resin and solvent, so as to make each crystal’s inherent hiding power and optical properties to the greatest play, show pure color image and image distinctness, and no occurrence of secondary pool when scattering in pigment system, thus effectively improving the product gloss. Applications electronic ink (PCB printed circuit board) Packaging 25kg/bag (lined with plastic film) or packaged as per request.
