- Aromatic Oils
Process Oils are distinguished from base oils in that many more key properties are reported and controlled. Since process oil applications are often quite specific, two seemly equivalent base oils do not perform identically. These differences are critical to good end product performance.
Process Oils include materials used to modify and improve product properties, assist in production, and extend rubber. Frequently the choice of a type of oil is based on it's solvency and/or color.
- Aromatic oils have the highest solvency and darkest colors and poor color stability.
- Naphthenic Oils have intermediate solvency and fair color stability.
- Paraffinic Oils have the lowest solvency, but highest color stability and lowest volatility.
Examples of applications include:
| Automobile Interior Moldings | Weather-Stripping |
| Automotive Underhood Parts | Wire and Cable Insulation |
| Adhesives, Sealants and Coatings | Gels |
| Polymer Modified Asphalts | Asphalt Extender |
| Tires, Tire Whitewalls, Tubes, and Inner Liners | Insulation |
| Dielectric Fluids | Drilling Fluids |
| Heat Transfer Fluids | Footwear |
| Agricultural Spray | Paper defoamers |
| Household Products | Furniture Polish |
| Roofing Compounds | Rubber Membranes |
| Carpet Underlayment Foam | Textiles |
Because Chevron ParaLux Process Oils are produced by all-hydroprocessing, they possess performance properties that surpass most conventional paraffinic process oils and approach or surpass many of the performance characteristics of technical white oils. These advantages include:
- Exceptionally low aromatic content
- Better color and UV stability than conventional paraffinic or naphthenic oils
- Almost complete resistance to degradation from ultraviolet discoloration and/or heat exposure
- Lower volatility for a given viscosity grade
- Lower volatility results in fewer emissions, so less make-up oil is needed and costs are minimized
- Excellent compatibility with rubber polymers which require paraffinic oils. Only all-hydroprocessed oils can deliver all of these advantages
Renkert Oil maintains inventory of all Chevron ParaLux Process Oils to ensure quick service and supply continuity no matter what the weather.
Renkert Oil offers Chevron ParaMount Process Oils where appropriate
What is the difference between Paramount and Paralux?
Both Paramount and Paralux premium process oils are produced using Chevron's modern all-hydroprocessing technology. As a result, both products offer exceptional oxidation stability, excellent initial color, and lack discoloration after UV and/or heat exposure. Although Paramount and Paralux are each utilized in a wide variety of rubber and nonrubber applications (such as processing aids, extender oils, adhesives, and textiles), Paralux is better suited for applications where color stability and aromatics content are essential, primary requirements. Alternatively, Paramount offers a high quality, more cost effective solution in applications where color and aromatics requirements are less stringent.
Paraffinic Oils
Paraffinic Oils are refined using either a solvent extraction method (Group I) or through a hydrocracking process (Group II & III). Solvent extracted paraffinic oils have high flash points, good color stability, low volatility, and a saturate level of 75-93%. Hydro-Processed paraffinic oils have a slightly higher flash than solvent extracted oils, are clear in color, slightly lower volatility, and a saturate level of 98-99%. These oils are particularly good in applications needing low color with stability or in high heat environments. Primary process oil applications are below.
| Rubber Process and Extender Oils | White Oil Feed Stock |
| Agriculture Spray | Adhesive Process Oils |
| Textile Specialities | Insecticide Carriers |
| Dust Control | Caulking and Sealant Compounds |
| Paper Process Defoamers |
These solvent-refined paraffinic process oils are highly saturated, offering low volatility and good oxidation resistance with low solvency power.
Hydro-Processed Paraffinic Process Oils
In addition to Chevron Paralux and ParaMount Process Oils, Renkert Oil also offers the Hydro-Processed paraffinic process oils below which are highly saturated, offering low volatility and superior oxidation resistance with low solvency power.
Naphthenic Oils have a wide variety of applications where they are used as process oils. Refined Naphthenic oils are available in a wide range of viscosity, flash, solvency, and color. Renkert Oil has multiple sources of naphthenic oils that allow us to provide the proper oil for the application. Primary process applications for naphthenic oils are below.
| Rubber Process and Extender Oils | Inks |
| Insecticide Carriers | Dust Control |
| Caulking and Sealant Compounds | Wood Treating Compounds |
| PVC Plastisols | Transformer Oils |
Naphthenic oils have lower flash points than corresponding paraffinic oils, and they offer good overall properties for a variety of applications.
Aromatic Oils
Aromatic Oils are derived from the extraction of aromatics in paraffinic oil production. Aromatic oils are dark in color, have relatively high flash points, low aniline points, and high aromatic content. Aromatic oils are normally used where a degree of solvency is desired to dissolve components or for a softening, or plasticizing effect. Uses for aromatic oils are below.
| Rubber Compounding and Extenders |
| Asphalt modification |
| Waterproofing and Sealant Compounds |
| Adhesives |
Most highly aromatic oils require labeling as carcinogenic under the OSHA Hazard Communication Standard.
