Mazut (Heavy Fuel Oil) – M100 (GOST 10585-99)
Mazut is a heavy residual fuel oil produced during the refining of crude oil. The most common export grade is Mazut M100, manufactured according to GOST standards and widely produced in Russia, Kazakhstan, Azerbaijan, and Turkmenistan.
Mazut is mainly used for:
thermal power plants
industrial boilers
heating systems
marine fuel applications

Typical Technical Specifications
Typical quality parameters for Mazut M100 include:
Density (at 20°C): 0.89 – 1.00 g/cm³
Sulfur content: 0.5 – 3.5% depending on grade
Water content: max 1.0%
Ash content: max 0.14%
Flash point: min 110°C
Kinematic viscosity at 100°C: max 50 mm²/s
Pour point: up to 42°C
Calorific value: approx. 9,000–9,500 kcal/kg
Mazut is classified primarily according to its sulfur content, which determines environmental characteristics and market suitability.

Petroleum Bitumen
Petroleum bitumen is a heavy hydrocarbon product obtained during crude oil refining. It is widely used as a binding material in road construction and asphalt production.
Russian and Central Asian refineries produce bitumen according to GOST standards, commonly used for road construction and infrastructure projects.
—
Main Bitumen Grades
Common grades supplied from Russia and Central Asia include:
BND 40/60
BND 60/90
BND 70/100
BND 90/130
These grades are used in road construction depending on climate conditions and pavement requirements.
—
Typical Bitumen Specifications
Typical technical characteristics include:
Penetration at 25°C: 40–130 (depending on grade)
Softening point: 45–55°C
Density: approx. 1.00 – 1.05 g/cm³
Ductility at 25°C: min 100 cm
Flash point: > 230°C
Bitumen grades are classified mainly by penetration value, which indicates hardness and suitability for different climate conditions.
