Oxidized
Bitumen
Overview
Oxidized Bitumen is produced by passing hot air through Penetration Grade Bitumen, which alters its properties, making it more rubber-like and resulting in a harder material. This process enhances the bitumen’s resistance to heat-related weight loss and significantly increases its softening point due to reduced thermal sensitivity.
Additionally, Oxidized Bitumen has a higher Penetration Index (PI), typically ranging between 2 and 8, compared to conventional road bitumen. This is attributed to its gel-like structure formed by asphalt accumulation.
Primarily used in industrial applications, Oxidized Bitumen is ideal for roof insulation, flooring, industrial mastics, pipe coatings, and paints. Its specifications are generally classified based on softening point and penetration rate.
Applications of Oxidized Bitumen:​
Oxidized bitumen serves a broad range of industrial purposes, including:
-
As an adhesive layer in roofing membrane systems
-
For hot-applied waterproofing applications
-
In the manufacturing of carpet tiles
-
As a base material for liquid bitumen-based coatings
-
In the production of bituminous paints and mastics
-
For corrosion-resistant coatings on pipes
-
As an anti-skid layer in piling operations
-
Used in the fabrication of roofing felts and soundproofing materials
-
Applied as an underbody sealant in the automotive sector
-
For protecting electrical cable joints, filling joints, sealing applications, and many other everyday industrial uses
