Blown Bitumen

Industrial-grade oxidised bitumen with high softening point for waterproofing & insulation.

IS:702 — 1988
Overview

Engineered for performance, dispatched with confidence.

Blown Bitumen is produced by passing controlled streams of air through hot paving-grade bitumen, oxidising it to dramatically raise its softening point and reduce its temperature susceptibility.

The resulting industrial-grade bitumen has a high softening point, low penetration and high viscosity — making it ideal for applications where the binder must hold its shape under heat rather than flow.

We supply standard industrial grades (85/25, 90/40, 115/15) per IS:702 for use in roofing felts and membranes, pipe and cable coatings, electrical insulation compounds and industrial waterproofing.

Applications

  • Roofing felts and waterproofing membranes
  • Pipe and cable protective coatings
  • Industrial waterproofing compounds
  • Battery & electrical insulation
  • Manufacture of bituminous paints and primers

Key Benefits

  • Very high softening point and heat resistance
  • Excellent waterproofing performance
  • Long-term chemical and weather stability
  • Higher viscosity for industrial applications
  • Reliable industrial-grade performance
