What is Bitumen 90/40?
Oxidized Bitumen 90/40 is an air-blown bitumen grade with a softening point near 90°C and a penetration value around 40 (0.1mm). This semi-hard grade balances high thermal stability with enhanced flexibility, offering better workability than harder grades while resisting deformation under moderate heat and mechanical stress.
Oxidized Bitumen 90/40 is commonly used in waterproofing systems, industrial insulation, roofing felt production, and pipe joint coatings for oil and gas pipelines. Its balanced hardness and flexibility make it well suited for moderate climates, isolation work, and general industrial applications requiring durable, weather-resistant performance worldwide.
