Rubber Process Oil (RPO) Definition


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 characteristics 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.

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 and Iran is one of the biggest RPO producers in Middle East.

Advantages of RPO

  • Good Abrasion Resistance
  • Good Low Temperature Flexibility
  • Low amounts of Waste Tyres in the process
  • Good Resistance to Reversion
  • According to with International Standards (EU 2005/69/EC)
  • Save Fuel and Energy Consumption
  • Extend Tyres Life Time
  • It is used by Tyre Manufacturers who make tyres for exporting to European Union.

As component in rubber formulations and manufacturing of products such as automobile tires, rubber shock absorbers, footwear, industrial hoses, wire, and cable coverings, flooring materials and carrier fluid or solvent in the manufacture of adhesives, sealants, polishes and carbon black.
