Oxidized Bitumen 85-25
Oxidized Bitumen 85/25 is an oxidized bitumen product generated by air blowing of pure petroleum bitumen. This process improves oxidized bitumen properties making it suitable for multiple industries and construction applications. The grade’s penetration is within the range of 20-30 Dmm at 25°C and the softening point is between 80-90°C. This grade is thermally stable and waterproof.
USAGE:-
Oxidized Bitumen 85/25 is primarily used in roofing and
waterproofing applications
due to its excellent weather resistance and high softening point (80-90°C), making
it ideal for roofing felts, membranes, and damp-proof courses. It is also widely
employed as a protective coating for pipelines and steel structures to prevent
corrosion, as well as in the production of bituminous paints, mastics, and sealants
for crack filling and joint sealing. And because of its exceptional waterproofing
and adhesive abilities,
It's also great for insulation when used with things
like cable joints. In construction, it serves as a durable binder for road repairs,
soundproofing, and industrial flooring. For application, the bitumen must be heated
to 180-220°C until molten, then applied via brushing, spraying, or pouring, with
proper safety precautions to avoid overheating and fumes. Its flexibility and
durability make it really popular for very serious and tough projects in big
factories and infrastructure work.
BENEFITS:-
The oxidated bitumen 85/25 provides many benefits, making it a preferred material for demanding industrial and construction applications. Its high soft point (80–90 ° C) ensures exceptional thermal stability, prevents deformation in warm climate, while its low entry value (20–30 DMM) provides better rigid and load-bearing capacity.The material distributes excellent waterproofing performance, causing impervious barriers that protect the structures from moisture damage and prolong their lifetime. Its strong adhesive properties enable excellent relations with various substrates including metals, concrete and sets. Additionally, the oxidated bitumen displays UV radiation, oxidation and increased resistance to aging, maintaining its integrity in harsh environmental conditions. The versatility of the material allows for various applications, from roof and pipeline coatings to industrial sealant and electrical insulation. It is easy to melt and apply at controlled temperatures (180–220 ° C), it provides practical handling by providing prolonged, cost-effective protection for infrastructure projects. These combined properties create a reliable, high-demonstration solution for waterproofing, corrosion protection and durable construction applications on oxidized bitumen 85/25.
