OXIDIZED BITUMEN 85/25
Oxidized bitumen 85/25 is a type of bitumen that has undergone a process of oxidation to improve its durability and performance in various industrial applications. Here’s a detailed breakdown:
Key Characteristics:
Penetration Grade: The numbers 85/25 refer to the softening point (85°C) and the penetration index (25 dmm, or deci-millimeters).
Softening Point: Oxidized bitumen 85/25 has a softening point of approximately 85°C, making it more resistant to temperature variations.
Penetration Index: The penetration index of 25 indicates that this bitumen is relatively hard, with low penetration when subjected to a standard needle penetration test.
Production Process:
Oxidized bitumen is produced by blowing air through heated bitumen. This process increases the bitumen's molecular weight, resulting in a more rubbery and elastic material that is less sensitive to temperature changes and more resistant to aging.
Applications:
Waterproofing: Due to its enhanced durability, oxidized bitumen 85/25 is commonly used in roofing, waterproofing membranes, and other moisture-resistant applications.
Industrial Uses: It is also employed in the production of roofing felt, pipe coatings, and anti-corrosion linings.
Road Construction: While oxidized bitumen is not typically used in road construction (as paving grade bitumen is preferred), it might be used in specialized applications where high temperature resistance is required.
Properties:
High Thermal Resistance: Suitable for environments with extreme temperatures.
Chemical Stability: It has good resistance to acids, alkalis, and salts.
Durability: Provides a longer lifespan in harsh conditions compared to non-oxidized bitumen.
This material is especially useful where high softening point and lower penetration values are needed, ensuring stability and performance under heavy loads and temperature fluctuations.
Oxidized bitumen produced by Asia Bitumen Factory is a high-quality bituminous product that undergoes an oxidation process to enhance its performance characteristics, making it suitable for a wide range of industrial applications. Asia Bitumen Factory is one of the prominent manufacturers and suppliers of bituminous products, particularly in the Asian and Middle Eastern markets.
Key Features and Specifications:
Oxidation Process:
The bitumen is oxidized by blowing air through it at elevated temperatures, which increases its molecular weight and alters its physical properties, making it more elastic and less prone to temperature-related issues.
Quality Grades:
Asia Bitumen Factory produces various grades of oxidized bitumen, including common grades like 85/25, 90/40, 115/15, and more. Each grade refers to specific softening points and penetration values, which determine its suitability for different applications.
