Bitumen:
non-crystalline solid or viscous mixture of complex hydrocarbons that possesses characteristic agglomerating properties, softens gradually when heated, is substantially soluble in trichlorethylene, and is obtained from crude petroleum by refining processes The most production type of bitumen in the world is petroleum bitumen which is obtained from crude oil distillation and they are classified based on Penetration Grade (standard ASTM-D5).
The vast majority of bitumen is used by the construction industry, as a constituent of products used in paving and roofing.
We are supplying the following grade and bitumen products with sustainable source of crude and refinery to assure our client with the best possible quality and services.
• Penetration Bitumen (30-40, 40-50, 60-70, 85-100, 80-100)
• Viscosity Grade (VG-10, VG-20, VG-30, VG-40)
• Cutback Bitumen (Rapid-Curing, Medium-Curing, Slow-Curing)
• Emulsion Bitumen (CRS, CMS, CSS)
• Oxidized Bitumen (75/30, 85/25, 85/40, 95/25, 105/35, 115/15)
• Modified Bitumen
The main grade of bitumen defines as Penetration Grade and we supplied the Pen Grade as per follow standard specification.
For other grades and products specification, you can contact us.

Fuel Oil
Fuel oil is the fraction obtained from the distillation of petroleum, in the form of distillate or residue. More broadly, Oil is any liquid petroleum product burned in a furnace or boiler to produce heat or used in engines to produce electricity, excluding oils with a flash point of boiler about 40°C (104°F).
- Fuel Oil CST 180:
Viscosity: CST 180 denotes centistoke (cst) at 180 degrees Celsius. It shows the fuel oil’s kinematic viscosity at this particular temperature. Fuel oil with CST 180 has a lower viscosity than fuel oil with CST 380.
Common utilize: Medium-sized ships and other vessels frequently utilize CST 180 fuel oil in their engines. It supplies the energy required for onboard systems and propulsion.
- Fuel Oil CST 280:
inadequate fuel oil quality. Often called furnace oil, the fuel is mostly made up of leftovers from the distillation of crude oil. Steam boilers on board ships, in power plants, and in industrial facilities are its primary use.
- Fuel Oil CST 380:
Viscosity: Centistoke (cSt) at 380°C is symboled CST 380. This suggests that the kinematic viscosity is higher than that of CST 180 fuel oil. Fuel oil CST 380 has a higher viscosity and thickness.
Common Use: Larger marine engines and power generation systems usually use CST 380 fuel oil. It is preferred in applications that call for a fuel that is heavier and more stable.
