It is possible for the PetroNaft Co. to produce bitumen with a permeability of 40/60, which is also known as Penetration bitumen 40/60. This particular bitumen product is among those that are included in the inventory of readily accessible items provided by the firm. An aeration procedure that is carried out on vacuum batons is used in bitumen manufacturing facilities to create a kind of bitumen known as bitumen 40-60. The extraction of vacuum baton, which is a necessary step in the production of bitumen, takes place in the vacuum of oil refineries at the foot of the distillation tower. Vacuum baton is a vital component in the manufacturing process of bitumen.


Petro Naft, one of the world’s top producers of bitumen products, creates bitumen 40/60, a premium subset of penetration bitumen. This kind of bitumen is often used in the building sector for a range of tasks, including waterproofing, waterproofing, paving, and road construction.

High levels of hardness and viscosity are seen in penetration bitumen. With a penetration range of 40 to 60 decimeters, bitumen blends like bitumen 40/60 stand out. This indicates that it is both medium in hardness and viscosity, making it appropriate for a variety of building jobs.

At Petro Naft, we use the most up-to-date tools and technology to manufacture Bitumen 40/60, guaranteeing that our goods exceed the highest criteria for quality. In order to provide a consistent and dependable product, our production process entails carefully choosing and combining the highest grade crude oil.

The strong resilience to temperature variations that Bitumen 40/60 has is one of its advantages and makes it the perfect material for usage in areas with severe weather. In addition, it has outstanding adhesive qualities, which makes it a great option for paving and road building.

We manufacture the highest quality Penetration Bitumen 40/60 in different types and export them from Iran and the UAE to other countries around the world.

Penetration bitumen 40/60 is a thermoplastic material, which means that it will become more flexible when it is exposed to hot temperatures, and it will become stiffer when it is exposed to low temperatures. Both the kind of crude oil that is used in the process of refining bitumen and the process of refining itself are possible elements that might have an influence on the way that bitumen behaves in terms of temperature and stiffness.

  • Very impressive adherence to the vast majority of different materials.
  • Protection from the effects of the atmosphere.
  • Long duration of service.
  • High levels of both flexibility and elasticity, with the goal of boosting the material’s resistance to fracture.
  • Acidic, alkaline, sulfate, and chloride substances do not affect this material’s resistance.

A few applications for penetration bitumen 40/60 include insulation, the production of liquid bitumen, and the construction of roadways in tropical areas. The adaptability of this product in the use of hot mix asphalt has also increased demand for it. The main goal of bitumen 40.60 impregnation is to provide a robust top layer. as an effective electrical insulating material, for instance, in the electrical industry; as one of the essential compositional elements in the process of precision casting; etc.

The chemical protection of metal pipes and other reinforced concrete structures makes significant use of the economical and chemically resistant 40-60 bitumen. Asphalt solutions, asphalt concrete, and sealing materials are the three most prevalent types of bitumen used in commercial and residential construction.

Petronaft Co. produces penetration bitumen 40/60 of the best quality in a variety of types and exports it from Iran and the United Arab Emirates to other nations worldwide.
