One of our most in-demand products is Bitumen 85/25, a semi-hard penetration grade bitumen known for its durability, flexibility, and suitability in demanding environments. This article will give you a detailed overview of Bitumen 85/25, its properties, applications, and why Faragam is the right partner for your bitumen needs.
What is Bitumen 85/25?
Bitumen 85/25 is a penetration grade bitumen that has a penetration value of 85 deci-millimeters at 25°C, and a softening point of around 55 to 65°C. The numbers “85/25” refer to the penetration rate and the testing temperature, which help users understand the product’s hardness and temperature resistance.
This grade is produced by blowing hot air into vacuum bottom residue, which changes the chemical structure and enhances the thermal and aging properties of the bitumen. As a result, it becomes more resistant to deformation, water, and oxidation, making it ideal for applications that require long-term performance under mechanical stress and temperature variation.
Key Properties of Bitumen 85/25
- Penetration: 85 ± 10 dmm
- Softening Point: 55–65°C
- Flash Point: Above 250°C
- Ductility: Minimum 1 cm
- Solubility in Trichloroethylene: Minimum 99%
These characteristics make Bitumen 85/25 especially useful in colder climates and in industrial settings where flexibility and adhesion are crucial.
Main Applications
Bitumen 85/25 is widely used in the following sectors:
- Waterproofing
Bitumen 85/25 provides excellent water resistance and is used in the production of membranes, damp-proof courses, and waterproofing layers in buildings and foundations.
- Roofing Felt Production
This grade is commonly used in the manufacture of roofing materials, especially in the layering of felt-based roofing rolls where long-term durability is essential.
- Pipe Coating
Pipes carrying liquids or gases often require bituminous coating to prevent corrosion. Bitumen 85/25 acts as a strong protective layer, especially in harsh environments.
- Asphalt & Road Construction
In cold regions, this grade is used in asphalt mixes to prevent cracking and damage caused by temperature fluctuations. It helps maintain road integrity during winter months.
- Adhesive and Sealant Industry
Due to its sticky and cohesive nature, Bitumen 85/25 is used in the production of bitumen-based adhesives, mastics, and sealing compounds.
