Oxidized (Blown) Bitumen 115/15
Oxidized Bitumen 115/15 is a high-hardness industrial grade bitumen developed for demanding applications that require exceptional thermal resistance and structural strength. With a softening point of 100–120 °C and low penetration range, this product delivers excellent stability at elevated temperatures and strong resistance to deformation under heavy loads.
This grade offers reliable performance in harsh environmental conditions due to its low loss on heating and high flash point, ensuring safer handling and longer service life. Its good solubility and controlled ductility provide balanced flexibility and strong adhesion, making it ideal for roofing membranes, waterproofing layers, pipe coatings, insulation systems, and specialized industrial sealing applications.
