Gilsonite Lumps

Gilsonite is mineral bitumen and its quality is like petroleum gilsonite and there is no difference between them. Only gilsonite is in lump mode but petroleum gilsonite is refinery product from oil that is in drum and therefore gilsonite price is very lower than petroleum md approximately lower than half of gilsonite price. Gilsonite can mix with petroleum md like md 60 70 with additives of mazut ( low quality fuel oil) , or sbs ( styrene butadiene styrene copolymer) for using in asphalt industries, gilsonite factories and waterproof roofing factories. Water proof roofing factories normally mixing gilsonite with sbs ( styrene butadiene styrene copolymer) and then using it in place of bitumen or oxidized bitumen. When asphalt companies using gilsonite their asphalt will not broke in cold weathers and hot weather it will not melt very soon.
