ATDM has a long history of supplying its Gilsonite-brand name products for the world market. The material now called Gilsonite or natural bitumen, mineral bitumen, mineral tar, mineral pitch, bituminous, natural asphalt was discovered in the Kermanshah since 2001. Modern geologists believe that the origin of Gilsonite is linked to the rich oil shale of the Green River Formation that underlies much of the basin. Deep vertical fissures in the earth’s surface were once filled with a heavy, viscous hydrocarbon that lost its volatile constituents and solidified millions of years ago.
Gilsonite is a glossy, black, solid hydrocarbon resin similar in appearance to coal or hard asphalt. It is brittle and lightweight and can be easily crushed into powder. Its unique chemical properties identify it as belonging to its own sub-group of the ATDM Gilsonite family. Gilsonite occurs naturally in a very pure state, and softens in a range of temperatures according to grade, from 302 to 464 degrees Fahrenheit (150-240 degrees Celsius). It has low specific gravity, high nitrogen content and very lower sulfur content. It is non-carcinogenic and safe to handle in its natural state.
