Penetration bitumen 30/45 has a permeability that falls anywhere between 30 and 45 and is created by vacuum aerating a distillation tower. The production of liquid bitumen, insulation, and the building construction industry are the three most common applications for this kind of bitumen. The use of bitumen 30-45 is most optimal in subtropical and very arid environments. This kind of petroleum grade bitumen is manufactured by using fractional-vacuum-destination crude oil as the starting material. In order to manufacture the bitumen penetration grade 30/45 that PetroNaft Co. provides, the vacuum residual feedstock is put to use.

The definition of bitumen of the penetration grade is derived from the penetration test. Designation determined only by penetration range. The depth to which a standard-loaded needle would vertically penetrate in five seconds in a sample of bitumen kept at a temperature of 25 degrees Celsius is used to assess penetration, which defines the hardness of bitumen.


Petro Naft Corporation, one of the major bitumen manufacturers in the world, produces bitumen 30/45, a subclass of penetration bitumen. Asphalt pavements and waterproofing materials are produced in large quantities using this high-quality product in the construction sector.

Bitumen 30/45 has special qualities that make it perfect for building projects where it has to survive harsh weather and high traffic. It has a high softening point, a low ductility, and outstanding adhesive qualities. It has a penetration grade of 30 to 45 deci-millimeter. Because of these qualities, it may be used to create materials for roads, waterproofing, and other industrial uses as well as for roofing.

The Bitumen 30/45 product is consistent with the excellent standards for which Petro Naft Corporation is recognized. This product, which is made using the most up-to-date tools and methods, is subjected to stringent quality checks to guarantee that it satisfies the highest requirements set by the sector.

The Petro Naft Corporation is a well-known producer of bitumen products and is aware of how critical it is to satisfy its clients. The business can provide Bitumen 30/45 to construction sites all around the globe in a timely manner because to its wide network of distributors.

We produce penetration bitumen 30/45 of the best quality in a variety of types and export them from Iran and the United Arab Emirates to other nations worldwide.

  • Iran Penetration Bitumen 30/45 ( Iran Bitumen 30/45 )
  • Emirates Peneteration Bitumen 30/45 ( Emirates Bitumen 30/45 )


Because it is thermoplastic, penetration bitumen 30/45 will become more malleable when exposed to high temperatures and more rigid when exposed to low temperatures. The mode of the bitumen changes depending on the temperature. Both the kind of crude oil used in the refining process and the process itself may have an effect on the way bitumen behaves in terms of temperature and stiffness.

• Extremely strong adhesion to the vast majority of materials

• Stability in the atmosphere

• Extended service life

Paving grade bitumen, also known as bitumen penetration 30/45, is a semi-hard penetration grade of bitumen that is used in the construction and maintenance of roadways. This grade of bitumen is most often used for manufacturing hot mix asphalt, which is used for bases and wearing courses. One of the most common grades of bitumen is called bitumen penetration 30.45, and it is utilized as a fundamental component in the production of all other bituminous products.

PetroNaft Co. manufactures the highest quality Penetration Bitumen 30.45 in different types and exports it from Iran and the UAE to other countries around the world.
