Description of Rubber Process Oil (RPO) 

Rubber process oil, both synthetic and natural is commercially used to produce products from rubber bands to a toy to the giant tires for various vehicles including aircraft. Rubber Process Oils are used during the mixing of rubber compounds.
Rubber process oil is an oil composition which has a kinematic viscosity at 100 °C of from 25 to 50 CST and which contains less than 3%. Polynuclear aromatic compounds are employed as a process oil for rubber compounds, especially aromatic rubbers.

Rubber process oil is used throughout a mix of rubber compounds. These facilitate in rising the dispersion of fillers and flow characteristics of the compound throughout more process. HJ OIl Co. rubber process oil is specially developed taking into thought the kind of rubber and also the end product applications

The process oil is compatible with aromatic rubbers but contains less toxic polynuclear aromatic compounds than conventional aromatic RPO. Rubber products of acceptable quality are produced by the use of the said oil composition.

Advantages Of RPO

1.Good abrasion resistance

2.Good low temperature flexibility
3.Low amounts of waste tyres in the process
4.Good resistance to reversion
5.According to with international standards (EU 2005/69/EC)
6.Save fuel and energy consumption
7.Extend tyres life time
8.It is used by tyre manufacturers who make tyres for exporting to European Union.

TYPES OF BITUMENS WE PROVIDE

  • Asphalt Oil

  • Aromatic RPO

  • Paraffinic RPO

    Paraffinic process oil is well-known according to its viscosity which meet ASTM D-445 with HS code 27079900. This class of hydrocarbons constitutes branched chain or straight linked hydrocarbon molecules of various viscosities. As the chain length increases, the viscosity increases and the rubber process oil (furfural extract RPO) becomes more viscous. They find extensive usage in Butyl rubbers. Paraffinic process oils with high viscosity and high flash point is better shelf life of the end product. Because paraffinic Furfural ekstrakt has higher viscosity and paraffinic content are preferred for achieving high retention of properties after ageing and higher loading of oil in applications like heat resistant / steam hoses and conveyor belts.
  • Naphthenic RPO

    Naphthenic are a class of hydrocarbons also referred to as cycloparaffins. Though their structure is similar to the aromatic ring, these are single bonded thus having a stable structure. Several such hydrocarbon rings may be linked indicating a variety of available grades. Naththenic rubber process oil has unique colour stability, solubility and good thermal stability makes them ideal for moulded articles, slippers, LPG tubes, floor tiles, etc.
  • Residual Aromatic Extract (RAE)

    RAE is a high viscosity aromatic process oil made from a residual oil fraction. It is used as extender oils in rubber and tyres. The Polycyclic Aromatic Hydrocarbon (PAH) content is less than 1ppm and total PAH less than 10ppm.
  • Treated Residual Aromatic Extract (TRAE)

  • Distillate Aromatic Extract (DAE)

    DAE is an aromatic oil with a large number of aromatic cycles in their composition; they are characterised by their low aniline point and their high solvent power. They are primarily used in formulation with polar rubbers of the SBR and NR types.
  • Treated Distillate Aromatic Extracted (TDAE)

    TDAE is not classified as carcinogenic as they contain a DMSO extract IP346 inferior to 3% and consequently a reduced PAH (Polycyclic Aromatic Hydrocarbon) content. Typically by factor 20-50 lower than HA oils. This environment friendly process oil has wide applications in tyres, tape & rubber industries. It is used as carrier oils, plasticizer, diluents & filling agent that remain in the final product contributing to both ease of processing and improved product performance in rubber industry.
  • Mild Extracted Solvate (MES)

  • High Sulfur Fuel Oil (HSFO)
