PERSOL offers bitumen origin of Iran for customers from a wide range of countries including China, India, Thailand, and Vietnam. To meet the needs of asphalt manufacturers, road builders and construction sector, PERSOL supply bitumen in different grades namely 40-50, 60-70, 85-100, based on softening points and penetration values as well as Natural Bitumen (Gilsonite).
Types of Bitumen
- Natural Bitumen
This bitumen is extracted from mines, it is also known as Gilsonite. It is used in many industries, including road construction, the paint industry, polish and insulation of tanks and tubes and molding.
- Coal Tar
This type of bitumen is a black or dark-brown residue produced by the heat treatment of coal
- Petroleum Bitumen
This bitumen is a mixture of hydrocarbons derived from petroleum. Black or brown, it varies from viscous to solid producing by air blowing process vacuum bottom.
- Road construction and Asphalt
- Waterproofing
- Roofing in construction
- Manufacturing of paints and printing inks
