What is Rubber Process Oil (RPO)?

Grades of Rubber Process Oil

Rubber materials are wide employed in human life. Rubbers, each artificial and natural are commercially used to manufacture product from rubber bands to a toy to the enormous tyres for varied vehicles together with aircrafts. Most typical usage is especially on tires, automotive provide trade, white product, constructions, textiles and medicine applications. The most parts of rubber compounds are rubber, reinforcing fillers, method oils and oil based mostly softeners. Alternative additives, like stabilizers, antioxidants, processing agents are enclosed in less quantity. Mineral oils with completely different compositions (paraffinic, naphthenic and aromatic) have been evidenced their importance as softeners and extender method oils in rubber compounds and are used for over 100 years.

Rubber process oil is made aromatic byproduct from solvent extracting method to modify physical properties of the processing and to cut back the price of the finished product.

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. IPOL rubber process oil is specially developed taking into thought the kind of rubber and also the end product applications. An oil composition which has a kinematic viscosity at 100 °C of from 32 to 50 cSt and which contains less than 3%. polynuclear aromatic compounds is employed as a process oil for rubber compounds, especially aromatic rubbers. The process oil is compatible with aromatic rubbers but contains less toxic polynuclear aromatic compounds than conventional Aromatic Rubber Process Oil. Rubber products of acceptable quality are produced using the said oil composition.

Depending on the kind of rubber and also the end rubber process oil uses, various kinds of rubber process oil are selected.

The vary of rubber process oil is broadly divided into :

  • Naphthenic types
  • Aromatic types
  • Paraffinic types

 

NAPHTHENIC OIL:

Naphthas are a category of hydrocarbons conjointly referred to as ‘cycloparaffins’. Although their structure is similar to the aromatic ring, these are single bonded so having a stable structure. Many such hydrocarbon rings are also linked, indicating a range of available grades.

Their unique color stability, solubility and good thermal stability make them ideal for molded articles, slippers, LPG tubes, floor tiles, etc.

AROMATIC OIL:

Aromatic extender oil well-known according to its viscosity which meet ASTM D-445 and Kinematic viscosity of transparent and opaque liquids 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 moulded 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.

The primary characteristics of aromatic hydrocarbons is that the presence of the double bonded combine ring carbon structure. Aromatic extracts procured from selected refineries and suitably blended to fulfil stringent specifications, are used for compounding batches to manufacture Tyres, Tubes, Hoses, Calendar sheets, etc.

PARAFFINIC OILS:

This category of hydrocarbons constitutes branched chain or straight linked hydrocarbon molecules of various viscosities. Because the chain length will increase, the viscosity will increase and also the rubber process oil becomes a lot of viscous. They find extensive usage in ethylene-propylene rubbers. These are more stable and have the highest flash purpose for a given viscosity.

Rubber process oil uses

  • As a component in rubber formulations and manufacturing of products like automobile tires, rubber shock absorbers, footwear, industrial hoses, wire and cable coverings, flooring materials and carrier fluid or solvent in manufacture of adhesives, sealants, polishes and carbon black.
  • To improve physical properties of vulcanization to cut back the value of the finished rubber compounds.
  • Tyre, Rubber and Droop industry.
  • Used as a lubricant in Rubber processing.
  • Used in manufacturing of White Oil.
  • Used as a component in Ink Production.

Advantages:

  • Low Staining
  • Low Volatility
  • Low Solubility Properties
  • Elastomer compatibility
RPO FURFURAL EXTRACT

RPO is using as the solvent extraction agent in the experiments. furfural extract well known as, fural, fur furaldehyde, pyromucic aldehyde, chemically, furfural extract participates in the same kinds of reactions as other aldehydes and other aromatic compounds. The aromatic stability of rubber process oil is not as great as in benzene, and RPO participates in hydrogenation and other addition reactions more readily than many other aromatics.

When heated more than 250 °c, furfural decomposes into furan and carbon monoxide, sometimes explosively. when heated in the presence of acids, furfural irreversibly solidifies into a hard-thermosetting resin.

 Rubber process oil (RPO)is used as a solvent in petrochemical refining to extract dienes (which are used to make synthetic rubber) from other hydrocarbons. furfural, as well as its derivative furfural alcohol, can be used either by themselves or in together with phenol, acetone, or urea to make solid resins. Such resins are used in making fiberglass, some aircraft components, and automotive brakes.

Furfural is also used as a chemical intermediate in the production of the solvents furan and tetrahydrofuran.

 Why Extender Oil and Rubber Process Oil Add to Natural Rubber?

Rubber process oils and extender oils are added to natural and synthetic rubbers for a lot of reason, for example:

  • Reduce blending temperatures during processing and prevent scorching or burning of the rubber polymer when it is being ground to a powder.
  • Decrease the viscosity of the rubber and thereby facilitate milling, extruding and general workability of the rubber compound.
  • Reduce mill and calendar shrinkage, to aid the dispersion of fillers, and to modify the physical properties of the vulcanized and/or finished rubber compound

How rubber process oil produce?

Rubber process oil is derived from petroleum crude oil when the additional volatile petrol and heating oil fractions are removed by distillation. Rubber process oil is mixtures of paraffinic, naphthenic and aromatic compounds of wide distribution of molecular weight. Rubber process oil is used in the rubber industry to enhance the process ability of rubbers and rubber compounds and increase the bulk of rubber so as to lower the price. Method aids are increasingly important for the rubber industry due to the following needs:

  • Improve efficiency and productivity
  • Lower energy consumption
  • Reduce production cost
  • Improve product quality
  • Rubber Process Oil

RPO Function:

  • Reduce viscosity
  • Reduce elasticity
  • Aid dispersion of fillers
  • Reduce power consumption

What is the kinematic viscosity of Rubber Process Oil?

The most important item of rubber process oil is that the kinematic viscosity @ 100°, kinematic viscosity at 100° c. is vary from 10 up to 70, most preferred viscosity is between 30 and 60. Once the kinematic viscosity is not up to ten, the normal properties of a cured rubber or shrivelled. Once it's above seventy method ability associate degrees an operability in mixing with a rubber become poor. Especially, just in case of associate degree aromatic cured rubber, once the rubber process oil having this vary of the kinematic viscosity is appropriately used in step with the properties of the rubber, the bar of injury of a plasticizer from the cured rubber is improved. The kinematic viscosity is measured in step with astm d 445.

What is the usual flash purpose in rubber process oil?

In the extract or rubber process oil flash purpose is vary from 170°c up to 250° c. Depends on reasonably rubber process oil whether or not it's aromatic rubber or paraffinic rubber. Within the method for manufacturing rubber process oil, it's preferred that the flash purpose is 210° c. And above. Once the flash purpose is low risk of flammability increasing thus in handling the rubber process oil it's going to make some problems. The flash purpose is measured per astm d 92.

What is a normal density of rubber process oil?

Normal density of rubber process oil is between 0.870 and 0.970 g/cm3, and therefore the a lot of like from 0.900 to 0.960 g/cm3. Once the density of the rubber process oil is totally different from on top of mentioned numbers in mixing with a rubber or ink, the mixing procedure should be modified. So we attempt to keep the quantity in stable vary the density is measured according to ASTM d 4052.

What is ASTM standard of rubber process oil? 

ASTM International is an international standard for rubber process oil that organizes, develops and publishes technical standards for a wide vary of materials as well as rubber process oil, rubber process oil, extract, furfural extract, DAE, TDAE, MES. ASTM’s members, representing producers, users, consumers, government, and academia from over 100 countries, develop technical documents that are a basis for producing, management, procurement, codes, and regulations.

A standard could be a document that has been developed and established in the consensus principles of the organization and that meets the requirements of ASTM procedures of rubber process oil and regulations. Full consensus standards are developed with the participation of all parties who have a stake within the standards’ development and/or use.

What is the aniline purpose in rubber process oil?

The lowest temperature that oil and aniline dissolve in one another in equal quantity is termed aniline purpose of the oil. The relative aromatic content of oil is indicated by aniline purpose. Oil with a high aromatic content have a low aniline purpose. The aniline purpose of rubber process oil measured consistent with ASTM D 611.

Rubber process oil is produced by crude oil distillation method obtained from the composition and chemical interactions and isolation material extracted called Raffinate.
