Description:
Oxidized Bitumen, also known as Blown Bitumen, is a specially processed grade of bitumen produced by passing air through it at high temperatures. This controlled oxidation process increases its viscosity, hardness, and softening point, making it highly durable and resistant to extreme weather conditions. Oxidized Bitumen is widely used in industrial applications such as roofing, waterproofing, road construction, and pipe coating due to its superior adhesion, flexibility, and thermal stability.
With excellent resistance to water, chemicals, and aging, Oxidized Bitumen is an ideal choice for applications requiring long-lasting performance and high mechanical strength. Its enhanced thermal resistance makes it particularly suitable for projects in high-temperature environments.
