bitumen 95/25

What is bitumen 95/25?

Bitumen 95/25 is a type of oxidized bitumen and softening point is 95C and penetration is 25 and categorized in flexible blown grade comapre bitumen 115/15 and mostly using in tyre industry and builing materials. The bitumen 95/25 is a specialized form process of dehydrogenation of asphaltenes. This process leads to the creation of long chains of asphaltene molecules through polymerization and condensation reactions.

Chemistry of Bitumen 95/25
