Look, I don't know what it's made of, or the specifics of the materials used. I know it's a bit more durable and harder than the standard silicone or resin erasers I've used prior to cleaning stone and ceramic sharpeners. And it works way better. Please note that I don't use the really strong erasers sold to remove rust from steel. They are hard on rocks and sticks.
