Gilsonite Natural Asphalt , Natural Bitumen , Hard Asphalt or Hard Asphaltum is used as a performance-enhancing agent for asphalt mixes. Gilsonite-modified paving mixes achieve higher PG grades and incorporate perfectly into the asphalt blend with no need for high shear milling as is the case with many other modifiers. Gilsonite can partially or totally replace, or complement, the use of SBS polymers in modified asphalts at a fraction of the cost. Gilsonite-modified asphalts have higher stability, reduced deformation, reduced temperature susceptibility and increased resistance to water stripping than non-modified asphalts. Gilsonite is also used to make both solvent-based and emulsion pavement sealers with superior appearance and weathering properties.
Gilsonite in Oil & Gas

Gilsonite is used in drilling mud fluids and oil well cementing. Gilsonite, in a range of softening points and particle sizes, is a standard ingredient in oil-based drilling muds used in shales and other difficult geological formations. The addition of specially-treated Gilsonite to water-based drilling fluids helps minimize hole washout by stabilizing troublesome shales, and seals off highly permeable sands while reducing torque and drag.  The addition of Gilsonite to oil well cements reduces slurry weight without loss of compressive strength and acts as an effective bridging and plugging

Iran Gilsonite, in comparison to the majority of the world’s Natural Bitumen suppliers, is a safe, friendly, reliable, experienced and affordable source for Natural Asphalt from Iran. In fact, through our independent assessments, when comparing Iran Gilsonite to the limited countries supplying Natural Bitumen, Iran’s Gilsonite, is many folds less in cost. Iran origin Gilsonite, was considered for export via Iran over a decade ago, and we have witnessed and participated in its formation into a fruitful exportable commodity from Iran via Bandar Abbas port to China’s and India’ market since its beginnings. Some Natural Bitumen importers regard Iran origin Gilsonite as Asia Gilsonite; The vigorous hard work of a select few in Iran to generate International recognition for this commodity has shaped a gracious foundation and commendable representation of this commodity into the world market. Today, the export of these goods via reliable Gilsonite Exporters gives us great pride, as it has accelerated the growth of the local economy in the immediacy of where Iran Gilsonite is regularly mined. Iran Gilsonite, in Association with its own Forwarding Shipping Company within its Holding, which is consequently affiliated with the most reputable shipping lines in the world, handles every aspect of exporting these goods via Iran’s Bandar Abbas port.
