Oxidized bitumen is essential for roofing and waterproofing due to its durability and resistance to harsh conditions. Basekim Chemical Production Co. offers two popular grades: bitumen 115/15 vs. 85/25. These grades differ mainly in softening point and penetration, which affect their performance. Therefore, selecting the right grade ensures long-lasting results and cost savings.
Basekim’s oxidized bitumen meets international standards and is supplied to over 140 countries. Furthermore, their ISO-certified production guarantees high quality and reliability. This article compares bitumen 115/15 vs. 85/25 by examining their properties, applications, and benefits. Whether you are a contractor or manufacturer, this guide helps you choose the grade that best fits your project needs.
know more about Oxidized Bitumen
Oxidized bitumen, also called blown bitumen, is made by blowing air through hot bitumen. This process increases its softening point and reduces penetration. The result is a durable, heat-resistant material. It’s ideal for roofing, waterproofing, and industrial uses.
Oxidized bitumen is graded by two numbers: softening point (°C) and penetration (0.1 mm). For example, 115/15 has a softening point of 115°C and penetration of 15. This makes it stiffer than 85/25, which has a softening point of 85°C and penetration of 25. Higher softening points mean better heat resistance. Lower penetration means less flexibility.
Basekim produces oxidized bitumen using advanced catalytic processes. Moreover, their products meet both ASTM and EN standards. In addition, rigorous lab testing ensures low volatility and high durability. Furthermore, available in drums or jumbo bags, Basekim’s bitumen suits diverse project needs. Consequently, this makes it a top choice for contractors and manufacturers worldwide.
Comparing bitumen 115/15 vs. 85/25
Basekim’s bitumen 115/15 vs. 85/25 grades serve different needs. Here’s how they compare:
-
Softening Point: Bitumen 115/15 softens at 115°C. It resists high temperatures better. Bitumen 85/25 softens at 85°C, suitable for moderate climates.
-
Penetration: 115/15 has a penetration of 15 (0.1 mm). It’s stiffer, ideal for rigid structures. 85/25, with a penetration of 25, offers more flexibility.
-
Heat Resistance: 115/15 performs better in hot regions. It resists deformation under intense heat. 85/25 is less heat-resistant but works well in milder conditions.
-
Flexibility: 85/25 is more flexible due to higher penetration. It handles slight movements in structures. 115/15 is less flexible but stronger for stable surfaces.
-
Durability: Both grades are durable, but 115/15 excels in extreme conditions. 85/25 suits general-purpose applications with less thermal stress.
Basekim’s advanced production ensures both grades have low oil content and high purity. This improves performance and longevity. Contractors can choose based on climate, project type, and budget. For example, 115/15 is better for tropical roofs, while 85/25 fits cooler regions or flexible membranes.
Applications in Roofing and Waterproofing bitumen 115/15 vs. 85/25
For roofing membranes: 115/15 is ideal for flat roofs in hot climates. Its high softening point effectively prevents melting or deformation. On the other hand, 85/25 works well for sloped roofs or cooler regions, offering greater flexibility.
In terms of waterproofing :both grades protect structures from water. Specifically, 115/15 is used for pipelines and underground tanks, as it resists high temperatures. Meanwhile, 85/25 is suitable for general waterproofing, such as basements or bridges.
Regarding industrial coatings: 115/15 is applied to metal surfaces to prevent corrosion in harsh environments. Conversely, 85/25 is used for less demanding coatings, offering a balance between cost and performance.
When it comes to road repairs, 85/25 is commonly used for crack sealing due to its flexibility, which adapts to surface movements. Although less common, 115/15 is still used in high-heat road applications where durability is crucial.
