Oil Products are Versatile Resources
Oil products are derived from crude oil, a natural fossil fuel. They have been an essential part of human civilization for centuries, providing energy, transportation, and industrial materials.
- Fuels
- Lubricants
- Petrochemicals
- Other Products like: Asphalt, Paraffin Wax and, Petroleum Jelly
Choosing Right
When selecting an o.i.l for a specific application, it is crucial to consider the following factors:
Viscosity Grade: The recommended viscosity range for the engine or component.
API Service Classification: The American Petroleum Institute (API) classifies motor oils based on their performance level.
Manufacturer’s Recommendations: Always refer to the manufacturer’s specifications for the correct o.i.l type and viscosity.
By understanding the different types of oils and their characteristics, you can make informed choices to ensure optimal lubrication and performance in your applications.
There are three different types of rubber process oil
Aromatic
The primary Characteristics of aromatic Hydrocarbons are the presence of the double bonded mix ring carbon structure.
Aromatic extender oil well-known according to its viscosity which meets 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.
Aromatic furfural extract RPO procured from selected refineries and suitably blended to meet stringent specifications, are used for compounding batches to manufacture tires, lactic, automotive tires and tubes, bicycle tires, tire 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 molded sheets, Tread rubber TDAE.
Also process o.i.l (furfural extract) has color stability, solubility, and good thermal stability.
Paraffinic
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. 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 RPO becomes more viscous.
Naphthenic
Naphtha is 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. 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.
- RPOs: Are intermediate products with excellent processability, loading (filler) characteristics, and tensile properties.
- RPOs: Are perfect intermediate products to optimize the required conditions. The compounder can achieve a workable mass with adequate dispersion of fillers through the selection of the correct process oils.
- RPOs: Are efficient secondary plasticizers in order to reduce cost.
- RPOs: Are offered in two kinds, Aromatic and Paraffinic.
Base Oil
Base Oil is the name given to lubrication grade oils initially produced from refining crude oil (mineral base oil) or through chemical synthesis (synthetic base oil). The base oil is typically defined as oil with a boiling point range between 550 and 1050 F, consisting of hydrocarbons with 18 to 40 carbon atoms. This oil can be either paraffinic or naphthenic in nature depending on the chemical structure of the molecules.
Base oils form the fundamental component of various lubricants, including motor oils, greases, and hydraulic fluids. They are derived from crude oil through refining processes and classified based on their viscosity and sulfur content.
Base oil has two different kinds: Virgin & Recycled
