Gilsonite (Natural Bitumen) – Low, Medium & High Ash Grades — Export from Iran
Available in Forms: Lump & Prilled – Ash Content: <10%, 10–15%, >15%
Gilsonite, also known as Natural Bitumen or Asphaltite, is a naturally occurring solid hydrocarbon resin mined from the earth. It is highly soluble in hydrocarbons, offers excellent adhesion, and provides thermal stability, making it ideal for industrial, oilfield, and manufacturing applications.
We supply premium-quality Gilsonite from trusted Iranian mines, available in Lump and Prilled forms, classified by ash content for specific industrial uses. Complies with international quality standards and suitable for bulk export to global markets.
Note: Gilsonite is classified by softening point and ash content. Lower ash = higher purity = better performance in coatings, inks, and foundry applications.
