Oxidized (Blown) Bitumen 90/15
Oxidized (Blown) Bitumen 90/15 is a high-quality industrial bitumen produced by blowing air through hot bitumen to improve its hardness, temperature resistance, and durability. It is designed for applications that require excellent stability under heat and strong resistance to deformation, while still maintaining adequate flexibility.
This grade offers a balanced combination of a high softening point and controlled penetration, ensuring reliable performance in both hot and varying climate conditions. Its low loss on heating and high flash point make it safe and stable during processing and application. Oxidized Bitumen 90/15 is widely used in roofing and waterproofing membranes, pipe coatings, insulation materials, industrial sealants, and protective coatings where long-lasting performance is essential.
