Gilsonite asphalt derived porous carbon is activated carbon made from natural bitumen rather than coconut shell, wood or coal. Research at Rice University produced material with a surface area of 4,200 m²/g from a low-cost asphaltic feedstock using a two-step KOH activation — a figure at the upper end of what activated carbon achieves by […]
Natural Asphalt History Natural Asphalt History What is Asphalt Asphalt is the inflammable substance we use to day to surface our roads and roof our homes. But it is much more than that, especially to the ancients. It was their glue, their means of waterproofing, and occasionally their method of making a living. It was […]
Asphalt crack sealer Asphalt crack sealer by Gilsonite Crack sealer produced by the blend of bitumen with SBS, Gilsonite, rubber process oil, crumb rubber in special temperature and pressure and using as sealing cracks and joints in the asphalt pavement and parking also cement pavement. It is used to seal expansion and longitudinal and transverse […]
Gilsonite Sealer Gilsonite Pavement Sealers Gilsonite’s proven properties make high-performance solvent-based and emulsion pavement sealers dry quicker, look better and last longer. As a natural antioxidant, it allows pavement sealers to stay blacker longer. Gilsonite’s unique molecular fractions rejuvenate the pavement being sealed. The strong bonding properties of Gilsonite help weatherproof the sealer. Making longer-lasting […]
Gilsonite Specification Gilsonite Specification Gilsonite is very fragile. It shatters easily. Rolling the Gilsonite between two drums tends to give the best particle distribution to use as raw material in carbon production. Normal Specification of Gilsonite with out any refining on it would be as below. Please remember that for each usage we must do […]

Natural bitumen Description of Natural Bitumen RAHA GILSONITE is one of the best suppliers of natural bitumen in Iran. Natural bitumen is a natural resinous hydrocarbon found in mines in the different city of Iran. Contrary to what most people believe Natural Bitumen is the same as the Gilsonite mineral, in fact, there are many […]
Gilsonite is used extensively onshore and on the offshore shelf, but its use in deepwater has been limited for one reason that has nothing to do with performance: a widespread industry belief that gilsonite and other asphaltic additives — the so-called black powders — cannot be discharged into a marine environment without breaching EPA standards.
