What is bitumen 90/10?
It is soft grade of oxidized bitumen with softening port 90C + 5 and penetration 10 +5 desimillimiter. Bitumen 90/10 is semi solid with some flexibility compare hard grades and mostly used in India market for waterproofing and battery. are produced by passing air through a bitumen feedstock under controlled conditions. This produces a higher softening point bitumen with reduced susceptibility to change with temperature and greater resistance to imposed stresses.
Differences of Bitumen with Asphalt 90/10?
Bitumen 90/10 is a complex combination of organic that is viscous, black and sticky. It is a complex mixture of high boiling point range of compounds and molecules with a relatively low hydrogen carbon ratio. In the most of countries the name of asphalt 90/10 and bitumen are synonymous, while in some area like Europe and Asia, both name have different meanings.Bitumen is pure but asphalt is mixture with aggregates.According to European Standard EN 12597 definition that the bitumen is a virtually in volatile, adhesive and waterproofing material derived from crude petroleum, or present in natural asphalt, which is completely or nearly completely soluble in toluene, and very viscous or nearly solid at ambient temperature, whereas asphalt is defined as a mixture of mineral aggregates and bituminous binder.
is a black or dark brown solid or semi-solid thermo-plastic material possessing waterproofing and adhesive properties. It is obtained from processing crude petroleum oil and is a complex combination of higher molecular weight organic compounds containing a relatively high proportion of hydrocarbons having carbon numbers greater than C25 with a high carbon to hydrogen ratio. It also contains trace amounts of metals such as nickel, iron or vanadium. It is essentially non-volatile at ambient temperatures and is soluble in carbon disulphide.
It is not known to present any safety, health or environmental hazard. Meanwhile, the American Society for Testing and Materials (ASTM) defines bitumen as a generic class of amorphous natural or manufactured, dark colored, cementitious substances composed principally of high molecular mass hydrocarbons, soluble in carbon disulfide. Asphalt also is defined as a cementitious material in which the predominating constituents are bitumens. The terms bituminous and asphaltic then refer to materials that contain or are treated with bitumen or asphalt.
How bitumen 90/10 produce?
Bitumen is a type hydrocarbon and after destination and remove of hydrogen more carbon will remove and become harder. By injecting hot air to bitumen the oxygen of air will combine with hydrogen of bitumen and make H2O and vapour and the remain bitumen is more carbon content and called oxidized bitumen.
Packing and method of peeling
We are able to supply bitumen 90/10 in 25Kg meltable bag,50Kg meltable bag,25Kg craft bag,50Kg craft bag,25Kg carton box. In 20ft container we can supply 22.8MT bulk or pallet. In case you are looking for drum packing it is possible in 185Kg Net and 220Kg drum.
Usage and application
It using for isolation and insulation and concrete surface coating, pipe coating, asphalt shingle, bottom sealing of carpet, paint and primer, mastic and membrane roof sheet, laminate and adhesive, roofing and flooring and enamel.Applications include use in roofing materials, waterproof papers, electrical components and many other building and industrial products. Classification is normally by both penetration value and softening point
Industrial applications are varied and cannot therefore be covered by general statements. The health hazards will depend upon the procedures involved, e.g.
- Lining and waterproofing operations may be considered as roofing or paving,
depending upon the technique.
- Flooring requires handling of hot mastic asphalts that are often laid by hand in
enclosed areas. The hazards are of the same type as those encountered in
using hot bitumen mixes, but the potential exposure to fumes is higher because
of the use of much higher temperatures (around 250°C), sometimes with
reduced ventilation. The bitumens are usually hard grades.
- Protective coating may give rise to concern when applied diluted in a solvent
which often contains aromatic hydrocarbons.
- Paper or cardboard impregnation is carried out a moderate temperature and the
end product is usually applied at ambient temperature.
How to order?
Optimum quotation is require to clear packing, quality and destination to be able to quote accordingly.We have sales agent in many many countries and if you looking for local purchase we are able to deliver DDP to the project.
Safety of usage and work
When it is in room temperature it is 100% safe and just should be in proper storage warehouse to be away from acid and fire but whenever it is on high temperature need to care about since the temperature is more than 230 centigrade.

Bitumen 90/10 is a commonly used material for building construction. According to environmental regulations, vegetable-based materials are applied for binder modification. Fluxed oxidized bitumen containing a bio-flux oxidation product increases the consistency over time. The efficiency of cross linking depends on the number of double bonds and their position in the aliphatic chain of fatty acid. The main goal of this paper was to examine the structural changes taking place during hardening bitumen with bio-flux additives. Two types of oxidized bitumens fluxed with two different oxidized methyl esters of rapeseed oil were used in this study. Various chemical and rheological tests were applied for the fluxed-bitumen at different stages of oxygen exposure. The oxidation of rapeseed oil methyl ester reduced the iodine amount by about 10%–30%. Hardening of the bitumen 90/10 generally results in an increase of the resins content and a reduction of the aromatics and asphaltenes.
