bitumen 85/25

bitumen 85-25

Bitumen 85/25, characterized by its sol structure, undergoes a semi-hardening process through vacuum fractionation under oxidation or air blowing. This involves passing air through heated bitumen to achieve the desired viscosity, resulting in a flexible yet non-flowing bitumen at ambient temperatures. The air-blowing process modifies viscosity, leading to variations in equilibrium.

Applications of Bitumen 85/25

Usage of Bitumen 85/25 finds extensive across diverse industries:

  • Chemical and Fuel: Used as a component in chemical and fuel production.
  • Paints, Lacquers, and Varnishes: A key ingredient in the formulation of paints, lacquers, and varnishes.
  • Paper-Pulp-Board and Textile Processing: Employed in the manufacturing processes of paper, pulp board, and textiles.
  • Road Construction and Pavement: Integral in the construction of roads and pavements.
  • Crack Seal and Repair: Used for crack sealing and repair work.
  • Civil Works and Roofing: A crucial component in civil engineering projects and roofing.
  • Construction Industries: Widely utilized in various construction applications.
  • Sealing and Insulating Buildings: Acts as a sealant and insulating agent for buildings.
  • Adhesive and Additive: Used as an adhesive and additive in construction materials.
  • Dust-Binding and Coating: Employed for dust-binding and coating purposes.
