Description of Oxidized Bitumen 95/25
Oxidized Bitumen 95/25 is a semi-solid, air-blown bitumen manufactured by oxidizing penetration grade 60/70 with hot air. It boasts better thermal stability, a higher softening point, and reduced temperature sensitivity compared to conventional penetration or viscosity grade bitumen. This makes it fit for demanding applications in construction, waterproofing, insulation, and more.
Applications
Because of its balance of flexibility-strength, Bitumen 95/25 is widely used in:
Construction & Civil Works: Waterproofing, concrete additive, joint sealing, and roof membranes.
Industrial Manufacturing: Paints, lacquers, varnishes, adhesives, corrosion protection coatings, and paper manufacture.
Automotive & Electrical: Undercarriage sealant, sound-deadening mats, insulation materials, and cable lamination.
Public Works: Pipes coating, hydraulic structures sealing, artificial turf binding, and anti-slip paving courses.
Manufacturing Process
Bitumen 95/25 is produced by blowing hot air into liquid bitumen through controlled oxidation. This causes chemical reactions such as dehydrogenation and polymerization to occur, forming functional groups that enhance the rigidity, adhesion, and chemical resistance of the product.
Storage & Safety
Store in a dry, well-ventilated place, away from direct sunlight and ignition sources.
Keep the product sealed in its original packaging to prevent contamination.
Use PPE (gloves, goggles, heat-resistant clothing) when handling.
When heating, never overheat to prevent fume generation.
Provide good ventilation in work areas.
