Bentonite is used as a bonding material in the preparation of moulding sand for the production of iron, steel and non-ferrous casting. The unique properties of bentonite yield green sand moulds with good flowability, compactability and thermal stability for the production of high quality castings.
Our 100% natural sodium bentonite exhibits outstanding characteristics for green sand moulding. Besides having a very high green compression strength, it also ensures a moderately high dry strength.
Our grade, with its extraordinary ability to retain bonding properties after heat exposure, provides a superior thermal durability and it allows the foundries to maintain active clay levels with reduced additions of bentonite or replacement sand.
