Oxidized Bitumen Grade 85/25


What is Oxidized Bitumen Grade 85/25?

Oxidized Bitumen Grade 85/25 is a type of bitumen that is produced by blowing air through liquid bitumen. This process causes the bitumen to oxidize, or become more brittle. The "85/25" designation refers to the penetration value, which is a measure of the bitumen's hardness. A penetration value of 85 means that a 100-gram needle will penetrate the bitumen to a depth of 85 millimeters at 25 degrees Celsius. This grade of bitumen is considered more brittle and harder than the penetration grade bitumen and less brittle than the Oxidized Bitumen Grade 95/25.

 

 

This grade of bitumen is commonly used in roofing applications, such as for the production of asphalt shingles, as well as for waterproofing and sealing surfaces. It is also used as a waterproofing membrane and insulation material. In addition, it is also used in the production of industrial and construction adhesives and also in the production of bitumen emulsions.

History of Oxidized Bitumen Grade 85/25

Oxidized bitumen grade 85/25 has been used in various applications for many years. The history of oxidized bitumen can be traced back to the early 20th century, when it was first produced by blowing air through hot bitumen. The process of oxidation modifies the properties of bitumen by increasing its softening point and improving its durability, making it suitable for a wide range of applications.

The use of oxidized bitumen grade 85/25 specifically can be traced back to the mid-20th century. This grade of bitumen is produced by blowing air through bitumen with a penetration grade of 85/100 at a temperature of approximately 250-270°C. The resulting product has a softening point of 85-95°C and a penetration value of 20-30 dmm. This grade of bitumen is commonly used in various industries, including road construction, roofing, and waterproofing.

Over the years, advances in technology and production methods have led to improvements in the quality and performance of oxidized bitumen grade 85/25. Today, the product is produced using advanced equipment and processes, which ensure consistent quality and performance. Additionally, research and development efforts continue to explore new applications for oxidized bitumen and other bitumen-based products, which are helping to drive growth and innovation in the industry.
