Oxidized Bitumen 85/25

1. Product Overview

Oxidized Bitumen 85/25 is a high-quality, air-blown bituminous binder engineered for demanding industrial applications requiring enhanced hardness, thermal stability, and resistance to deformation. It is primarily used in waterproofing, roofing, insulation, sealants, and protective coating systems where long-term durability is critical. Its controlled softening point and penetration characteristics provide reliable performance under varying temperatures and mechanical conditions. As a specialized industrial bitumen grade, it supports consistent formulation and dependable large-volume procurement for infrastructure and manufacturing operations.

3. Core Industrial Applications

• Waterproofing: Used in membranes, mastics, coatings, and moisture-barrier systems requiring strong water resistance.
• Roofing: Suitable for roofing compounds and protective systems requiring thermal stability and durable adhesion.
• Pipe & Infrastructure Protection: Applied in corrosion-resistant coatings and protective systems for pipelines, foundations, and underground structures.
• Sealants & Mastics: Provides hardness, cohesive strength, and temperature resistance in industrial sealing formulations.
• Electrical & Thermal Insulation: Used in selected insulating compounds where stable dielectric and thermal performance is required.
• Industrial Coatings: Supports protective coating formulations designed for demanding environmental exposure.

Its higher softening point and controlled penetration provide greater dimensional stability and resistance to flow than softer conventional bitumen grades, supporting longer service performance in heat-exposed applications.
