I sell industrial minerals to the manufacturing industry(started company 2 years ago).
these are all non metalic minerals, which are called functional fillers to manufactures like, paint manufactures, glue, agricultural chemical manufactures and plastic extruders, and other manufacturers, some day to day products where you will find our products are: carpets, bread, rubber, toothpaste, braso, PVC, ceramics, paper, glass(including wine and beer bottles).
basically these filler are every where, doens't matter where you are they are found in any product within a 0.5meter around you.
so if you are manufacturing and you're using filler, send me a PM.
