Viscosity Grade Bitumen

Is standard petroleum grade bitumen produced from vacuum bottom Oxidation. Viscosity Grade Bitumen is one of the most widely used bitumen grades in the world. This type of bitumen is easier to work with (both mixing and compaction) and its resistance to rutting is more predictable. At a standard temperature viscosity testing system leads to the classification of bitumen products into four VG grades:


Vacuum Residue

Vacuum residue (VR) is a good substitute to low-viscous bitumen grades. It is widely used to prepare bitumen mixes especially for use in cold climates, where low viscosity and higher penetration are very important.

Penetration Grade Bitumen

Is a standard bitumen usually sued as paving grade bitumen essential for road construction and for the production of asphalt pavements with superior properties, and it's very important once it bounds the aggregates and creates a unique cohesion and stability to the bituminous mix. 
The penetration test is carried out to characterize the bitumen, based on the hardness. Penetration grade bitumen has a very wide range :
- 40/50
- 50/70
- 60/70
- 70/100
- 80/100
- 120/150
- 160/220

Lubricating Oil

Lubricants are highly value-add petroleum refinery products. Unka Sun provides best quality of both Heavy Lubricating oil and Light lubricating oil.
