Oxidised Bitumen 85/25

Oxidized Bitumen 85/25 (also called Blown Bitumen 85/25) is a specialized grade of bitumen that has undergone a controlled oxidation process. This process modifies the physical properties of the bitumen, making it more rigid and less sensitive to temperature changes compared to penetration-grade bitumen.

Main Applications Of Oxidised Bitumen 85/25

Oxidized Bitumen 85/25 has several industrial applications due to its high softening point, low penetration value, excellent adhesion, and resistance to water and chemicals. Below are its primary applications:

  1. Waterproofing and Roofing: Used in roofing membranes, sealants, and damp-proof courses to prevent water and moisture infiltration.
  2. Road Construction and Maintenance: Acts as a crack sealant, joint filler, and expansion joint material in roads and bridges.
  3. Pipe Coating and Corrosion Protection: Protects pipelines and metal surfaces from corrosion, especially in harsh environments.
  4. Adhesives and Flooring: Serves as an adhesive for tiles and carpets and forms a durable underlay for flooring.
  5. Electrical Insulation: Provides insulation for electric cables and is used in capacitors.
  6. Construction Industry: Improves water resistance in concrete and enhances flexibility in mastic asphalt.
  7. Marine and Offshore Applications: Protects marine structures and insulates ship decks.
  8. Packaging and Container Sealing: Coats drums and containers to prevent leakage and corrosion.

This grade’s resistance to high temperatures and moisture makes it ideal for demanding environments like infrastructure, industrial setups, and marine settings.

Various Packing Method for Oxidised Bitumen 85/25

Packing Oxidised bitumen is an essential process to ensure its safe transportation, storage, and handling. The method of packing often depends on the transportation method, and the end-use. Here are the various methods used to packing oxidised bitumen:

Steel Drum Packing

Oxidised Bitumen is commonly packed in new or re-conditioned steel drums, which are robust and provide good protection during transportation.

Kraft Bags / PP Bags / Carton Box

Oxidised Bitumen is packed in Kraft/PP Bags or Carton Box of 25Kg, which are robust and provide good protection during transportation.
