Rubber Process Oil (RPO) Definition20200326153903WyOb

Rubber Process oil is produced by Crude oil distillation process obtained from the composition and chemical interactions and isolation material extracted called Raffinate. The primary characteistics is the presence of the double bonded mix ring carbon structure. Aromatic extracts procured from refineries are suitably blended to meet stringent specifications with different Viscosity. Heavy RPO is also an aromatic process oil with higher viscosity and is specifically developed for use as an extender oil in the manufacture of polystyrene butadiene rubber. This aromatic type of rubber process oil is dark in colour and has good solvency. It is compatible with most rubber polymers and suitable for use in the manufacture of automobile rubber tyres, belting, battery case etc. where colour is not an important parameter. Heavy RPO was specially developed for use in SBS rubber.

Iran is one of the biggest RPO producers in Middle east and hjoil has a huge share of this production.

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.


  • Asphalt Oil

  • Aromatic RPO

    Aromatic extender oil well-known according to its viscosity which meet ASTM D-445 and Kinematic viscosity of transparent and opaque liquids HS code 27079900 it has different grades famous as high(heavy) , medium , low(light) viscosity, TDAE , MES and DAE . The primary characteristics of aromatic hydrocarbons are the presence of the double bonded mix ring carbon structure. Aromatic furfural extract rubber process oil (RPO) procured from selected refineries and suitably blended to meet stringent specifications, are used for compounding batches to manufacture tyres, lactic , automotive tyres and tubes, bi-cycle tyres, tyre re-treading materials, belting, hoses, battery casings and containers, extruded products, technical molded goods and rubber articles with reclaim rubber due to high solvency., calendared and moulded sheets, Tread rubber TDAE oil.also process oil (furfural extract) has a colour stability, solubility and good thermal stability makes RPO ideal for moulded articles, slippers, LPG tubes, floor tiles, etc.
  • 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)
