According to the seller, it is noticeable in one of the photos that the drum is “caved-in”. This is called a “paneled drum”. Since the slurry was made in PEG-400, the abrasive is still wet with the PEG. The PEG was removed by MEMC before shipment of the caked JIS abrasive. But, there still remains some small amount of PEG in the abrasive. Over long time periods, the PEG will work its way into the drum wall and SLIGHTLY soften the plastic. When this happens, that part of the drum tends to “cave–in”. This “panel” effect happens only to a small fraction of the drums, but it does happen. But, please understand, there is NO LOSS OF INTEGRITY TO THE DRUM, THE ABRASIVE, OR THE PEG. This is a simple mechanical process that occurs in some plastic drums when any solvent is stored in the drum for a number of years. This happens only because plastic drums of PP (polypropylene) are NOT all manufactured the same. In some drums, there are small areas where the drum wall is somewhat thinner than the rest of the drum. So, that drum may be subject to the “panel effect”. They simply want you to know that some of the drums are “paneled” by the PEG-400. The abrasive RETAINS FULL INTEGRITY with NO CONTAMINATION FROM THE DRUM.
The photos of samples were taken of the high purity JIS Abrasive Cake Core plus the thin surface layer of contaminating Si solids (called kerf). The surface kerf shown in the cut drum (i.e.; MVC-005S / MVC-009S / MVC-011S), constitutes only a small level of the abrasive solids. The rest of the solids below the Si kerf layer on the surface of the cut drum is a high-quality JIS - abrasive shown in MVC-001S and MVC-009S. Looking carefully at MVC-009S, you will see how the JIS abrasive core cake is greenish compared to the black/wet Si solids kerf. That greenish color is a distinctly visual indicator of high purity JIS abrasive. It was also taken some particle size distribution curves (PDCs) from a variety of random drums.
