ConoPure Process Oils

The Difference Is Perfectly Clear.

​Purity is the key to ConoPure™ Process Oil performance.

ConoPure™ paraffinic process oils are produced using an advanced hydrocracking and catalytic dewaxing process that yields extremely pure colorless products, virtually free of aromatics, polar compounds and sulfur. These highly refined oils exhibit properties that are ideal for use as process oils and extenders in rubber, plastics, adhesives and numerous other applications. End use products include:

  • “Under the hood” automotive parts
  • Pulp & paper defoamers
  • Spray oils for herbicides and pesticides
  • Automotive moldings

Because ConoPure™ process oils are produced using an advanced hydrocracking and catalytic dewaxing process, their performance properties exceed most conventional paraffinic and naphthenic process oils.

These properties include:

  • Highly saturated
  • Extremely pure
    • Virtually no aromatics
    • No sulfur
    • No polar compounds
    • No nitrogen
  • Colorless and non-staining
  • Low volatility
  • Highly stable
    • Thermal
    • UV
    • Oxidation
    • Color
  • Excellent compatibility with rubber polymers
  • Meets 21 CFR 178.3620(c)
  • Very low DBD/DBF

These properties create distinct advantages in a wide variety of process oil applications.

ConoPure™ Advantages in EPDM & Other Rubber Applications

Color: With colorless ConoPure™ process oils, designers can produce much lighter colored polymers and finished rubber products.

Stability: ConoPure™ process oils are so completely free of impurities that they are much more resistant than other oils to oxidation and discoloration from heat and light. That means more stable color and longer life for finished EPDM and other rubber products.

Low Volatility: Due to the virtual absence of aromatics, ConoPure™ process oils produce lower emissions during polymer production, compounding and fabrication. This low volatility also contributes to their stability in end use applications. Their exceptional stability when exposed to heat makes them ideal for high temperature environments.

ConoPure™ process oils can be used in a wide variety of applications in natural rubber, EPDM, EPM, polyisoprene and butyl rubbers, as well as certain thermoplastic elastomers. Typical end use applications include:

  • Polymer production
  • “Under the hood” automotive parts
  • Automobile moldings
  • Tire whitewalls
  • Sound and vibration dampening materials
  • Wire and cable insulation and sheathing
  • Weatherstripping and rubber membranes
  • Roofing compounds
  • Sporting goods
  • Conveyor belts for food processing
  • High temperature applications

ConoPure™ Advantages in Adhesives Applications

ConoPure™ oils are well suited for adhesive applications where long-term color stability is important, such as medical and decorative adhesives. The UV stability and colorless characteristics of ConoPure™ oils help create finished products that will not fade or discolor quickly. In addition, the low volatility of ConoPure™ oils is desirable for use in building and household adhesives.

ConoPure™ Advantages as Spray Oils

Phillips 66’s hydrocracking process results in highly saturated oils with very high unsulfonated residue values and narrow distillation ranges. This makes ConoPure™ oils safer for plants. They are ideal for spray oil applications requiring a low toxicity pesticide or a more effective herbicidal adjuvant.

ConoPure™ Process Oils in Other Applications

ConoPure™ process oils are suitable for a wide range of other applications including use as a component of non-food articles intended for use in contact with food in accordance with FDA regulation 21 CFR178.3620(c). These other applications include:

  • Packaging adhesives
  • Defoaming agents
  • Filters
  • Textiles and textile fibers
  • Metallic foil manufacturing
  • Coatings and sealants

Using advanced hydroprocessing technology, Phillips 66 converts crude oil molecules into extremely pure colorless products, virtually free of aromatics, polar compounds and sulfur. The result is a paraffinic mineral oil free of the impurities that limit the performance of conventional process oils.

Here is how the process works:

  1. Feedstock is separated into distillates and vacuum gas oils.
  2. Waxy vacuum gas oil molecules flow to the hydrocracker to begin conversion.
  3. Hydrogen is introduced to saturate the molecules and remove impurities such as nitrogen, sulfur, oxygen and heavy metals.
  4. Hydrocracking, under conditions of extreme temperature and pressure in the presence of a catalyst, converts aromatic molecules into saturated paraffins.
  5. The altered stock is noticeably lighter in color due to the absence of contaminants.
  6. Long waxy paraffin molecules are restructured into shorter, branched isoparaffins which resist gelling and improve low temperature pumpability.
  7. Hydrogen is introduced again to remove any remaining aromatics and impurities, enhancing the oxidation and thermal stability of the now colorless oil.

​Loading Requirements

Excel Paralubes

Westlake, Louisiana

General Requirements:

  1. All railcars must be single compartment center loading (No split cars can be loaded).
  2. All railcars must have "truck center" lengths ranging from 41' 9" to 50' 9".
  3. Outage tables with shell capacities and tare weights will be provided to Excel Paralubes prior to loading. Proper stencil is required on railcar, (i.e. tare weight, gross weight, etc.) In addition, please advise as to whether the railcar is lined or unlined. All release samples will be taken from the top of the railcar. A standing vehicle waiver is approved by the partners for all unlined railcars waiving particulates in the bottom outlet sample.
  4. Customer should verify quality & quantity of product before off-loading. If there are any discrepancies, contact your Customer Service Center immediately.
  5. Excel Paralubes will only load clean railcars or Excel Paralubes base oil residual railcars. As long as the previous content of a customer-supplied railcar was an Excel Pure Performance base oil, any subsequent load(s) can be of any grade of Excel base oil without additional cleaning. The railcar will receive a preload inspection and must be clean and dry. (Customer-supplied railcars with non-Excel Paralubes residual oil will be considered for loading after a vehicle waiver request has been approved and a previous content MSDS has been supplied.
  6. Excel Paralubes will load railcars which have the top valve mechanism that opens the bottom outlet valve, with the release sample taken from the top of the railcar instead of the bottom outlet. A visual check sample cannot be taken from the bottom outlet.
  7. Phillips 66's standard demurrage policy allows customers to keep the railcar seven days on site at no charge. Detention charges begin on the eighth day and accrue at a rate of $50 per day. This rate is subject to change without prior notice.
  8. When Phillips 66's railcars have been offloaded, reverse route the railcar back to: Excel Paralubes, Westlake, LA.
  9. Superior Railcar Services, Inc. provides maintenance and repair service at Excel Paralubes. This contractor will also service customer railcars if necessary. Prior to performing any work on customer railcars, Phillips 66 Customer Service Representatives (CSRs) will make every effort to notify the customer about immediate maintenance required for repair confirmation/approval.  If the CSR cannot reach the customer in a timely manner, all estimated repairs under $50.00 will be completed without customer consent to avoid delayed shipments. No repairs over $50.00 will be performed without customer consent.  Repair costs will be invoiced to the customer directly by Superior Railcar Services.
