Pars Bitumen’s Oxidized Bitumen 105/15

 

Description: 

At Pars Bitumen, we are pleased to offer our premium grade Oxidized Bitumen 105/15, a blown or air-oxidised bitumen tailor-made for demanding industrial and construction applications. This grade is produced by introducing hot air into penetration-grade bitumen, elevating its softening point and reducing its penetration degree, thereby increasing hardness, thermal stability and durability.
The “105/15” designation indicates a mid-point softening point around 105 °C and a penetration around 15 dmm at 25 °C.
In the following sections, we’ll dive into specific features, applications, keywords for SEO, and conclude why this grade is an excellent choice when supplied by Pars Bitumen.

Specific Features of Oxidized Bitumen 105/15

Here are the key technical and performance features:

High Softening Point (~100-110 °C): Enables the material to remain solid and stable under elevated temperatures, preventing flow or deformation.

Low Penetration (~10-20 dmm): Indicates a hard consistency, meaning good resistance to deformation under load, shear, or high stress.

Excellent Adhesion & Binding: The oxidation process improves bonding to substrates like metal, concrete, membranes, making it suitable for coatings, adhesives and protective layers.

Water & Chemical Resistance: Suitable for waterproofing, corrosion protection, and harsh environment applications thanks to its hardened structure.

Thermal Stability & Durability: Withstands cycles of heat and cooling, maintains performance over time; many sources note 10 years’ validity under correct storage/handling.

Versatile Packaging and Supply Flexibility: Available in drums, bulk, bags, Kraft-bags—allows flexibility in logistics and application.

 

 

Applications of Oxidized Bitumen 105/15

Thanks to its enhanced properties, this grade is used across a broad array of sectors:

Roofing & Waterproofing:

Ideal for hot-applied waterproofing membranes, roof felts, high-temperature flat roofs, basements, tunnels where stability under heat is critical.

Also used in waterproof coatings for building envelopes, ponds, reservoirs.

Pipeline Coating & Corrosion Protection:

Utilised for coating steel pipes in oil/gas, water, industrial supply lines, where the binder must resist harsh environments and temperature fluctuations.

Also used in joint sealing, anti-corrosion mastic, protective linings.

Industrial Flooring, Adhesives, Insulation:

Functions as a binder in mastics, adhesives, insulation panels, synthetic turf backing, and industrial paint bases.

Used in sound-proofing, automotive under-carriage sealants, electrical cable joint protection.

Civil Works & Special Applications:

For tunnel linings, dam waterproofing, canal linings, expansion joints, hydraulic structures where durability and high softening point matter.

Also used in crack-sealing, pavement maintenance where a harder bitumen is preferred.
