Grade 85/25

Description of oxidized bitumen 85/25

At the bitumen production reactor, during the air acting, the mixture of the two Vacuum Bottom (VB) and Vacuum Silas (VS) feedstock is put under a special degree of pressure and temperature between 200-300˚C of which the hydrogen atoms content in bitumen molecular oxidize to oxygen of air, and obtains with higher hydrocarbons polymerization reaction that has lower penetration and higher softening points than the primary pure bitumen. This kind of bitumen 85/25 has the softening point of 85 and permeability of 25.
Oxidized bitumen 85/25 is a semi-solid oxidized grade of pure petroleum bitumen categorized in polycyclic aromatic hydrocarbons is normally used for different purposes in the construction business. Oxidized bitumen 85/25 is based on petroleum bitumen which is made by blowing bitumen 60/70 by very hot air. This product, utilized in the industrial sector, exhibits predominantly “solid” characteristics at ambient temperatures and provides SUPERIOR adhesive and waterproofing qualities when applied hot and allowed to cool than Oxidized Bitumen.
jey pasargad company guaranty the quality of jey pasargad Oxidized bitumen 85/25 with the arrangement of the international inspector to check quality and quantity of the bitumen 85/25 during the loading to the vessel and controlling the production by QC by batch test report before shipping. jey pasargad Company guarantees the quality to meet with ASTM.

Uses of oxidized bitumen 85/25

Oxidized bitumen 85/25 uses in the chemical, fuel, paints, lacquers, varnishes, paper-pulp-board, textile processing, road construction, pavement ,crack seal and repairmen, civil works, roofing, construction industries; sealing and insulating buildings, adhesive, construction materials additive, dust-binding, insulating and impregnating agent, make rubber and plastic products. The oxidized bitumen 85/25 products are for paving. also used in asphalt-based paints for corrosion protection of metals, in lining public works structures, adhesives in electrical laminates, base for synthetic turf; typical uses for bitumen 85/25 used also for water-proof application and corrosion resistance for pipe coating, Portland cement pavement, hydraulic applications, paint manufacturing, caulking, mastics, and damp proofing.

bitumen 85/25 is using insulation and isolation bitumen membrane sheet. Also, Car undercoating Automobile industry is specially required for Blown Asphalt. Vehicle undercoating material is based on Bitumen. Bitumen provides excellent waterproof, dust proof and noise proof for automobile undercoating.

Oxidized Bitumen 85/25 Application

This can be used for a wide range of applications.
This bitumen is ideal for construction, paving, and road maintenance.
One of the canal lining’s components is oxidized bitumen 85/25 also suitable to building embankments and dams in hydro projects.
In roofing industry it can be used for roof coatings. It can also be used as a thin bitumen membrane beneath the shingles and also a raw material for carriage roofing compounds and liquid roof coatings.
It is one of the most used flooring materials. Acid and alkali proof bitumen mastic that can be used in a wide range of industries.
In oil and gas industry it can be used for coating pipelines. Coating the pipelines with oxidized bitumen 85/25 can protect pipes from corrosion and rust.
It is a raw material of lithium-ion batteries and wires and can seal the electrical junction boxes. It is a good adhesive for laminated boards.

Storage/handling of oxidized bitumen 85/25

The validity of bitumen 85/25 is 10 years with multi-time heating and cooling, please refer to MSDS.
