Test Method Notes
- BET surface area values for WB10D and WB35D are measured by 5 point BET
- BET surface area values for SBG, WB310 and WB37 are measured by 1 point BET
- Oil absorption values are measured using a Brabender Absorptometer E
- Particle size values were measured using Laser Light scattering
- Values for tamped density and mean particle size are typical values
