Bitumen

OXIDIZED BITUMEN

Blown bitumen grades or Oxidized Bitumen are produced by passing air through the penetration grades. This process gives the bitumen more rubbery properties than its original formula and they are simply harder bitumen. Hard bitumen under controlled temperature conditions is widely used as an anti-slip layer compound in the piling industry, for manufacture of roofing felts, the roofing and waterproofing industries, for sound dampening felts and under carriage sealant in the automotive industry, electric cable joint protection, joint filling compound, sealant compound and many others. Also used in sealing saw cuts and joints where expected movements are minimum. It is also used in the manufacturing of bituminous marine mastic for the oil & gas pipeline joints.

APPLICATIONS


  • Oxidized Bitumen has a wide variety of industrial applications
  • As a bonding bitumen for roofing sheet membranes.
  • As a hot applied waterproofing layer.
  • Carpet tile manufacture.
  • For rust proof pipe coatings
  • Used as an anti-slip layer compound in the piling industry
  • Used for production of roofing and sound dampening felts, Used as under carriage sealant in the automobile industry, electric cable joint protection, joint filling compound, sealant compound and many more in our day to day life.

PENETRATION GRADE BITUMEN

Penetration Grade Bitumen is Bitumen classified using the penetration property. Penetration grading’s basic assumption is that the less viscous the asphalt, the deeper the needle will penetrate. Bitumen which is produced during the process of oxidation of vacuum bottom (the Bitumen production feedstock that derives from distillation tower residue in vacuum oil refineries) at bitumen production unit in a manner that its penetration point (kind of test to indicate the hardness of bitumen) in specified group is classified in different grade of Bitumen. Penetration Grade Bitumen is commonly used in road surfacing, and some industrial applications. Additional processing yields other grades of bitumen products and their application
