Coated calcium carbonate
Natural calcium carbonate is hydrophilic. That means it likes water, but is pretty unfriendly towards organics like polymers. Yet the plastics industry needs a cheap white filler just as much as anyone else! If you mix ground calcium carbonate into plastics, the high surface energy of the particles cause a lot of friction, which you don't want.
