Rubber compounding ingredients. Precipitated silica. Determination of aggregate size distribution by disc centrifugeWhat is ISO 20927 Rubber compounding ingredients about? ISO 20927 provides methods and procedures for determining the aggregate size distribution by disc centrifuge. ISO 20927 specifies a general method for determining the aggregate size distribution (ASD) silica by using a disc centrifuge according to the principle of sedimentation. As pre stage, the silica de agglomerated in water using strong ultrasonic power treatment. The method described in ISO
