Naphthenic base oils generally have intermediate VI's and very low pour points which make them useful in the manufacture of specialty lubricants. Dewaxing is normally not required due to the low quantities of linear paraffins (n-paraffins).

May 10, 2022 · Low pour point, excellent liquidity, low wax, and low aromatic content characterise naphthenic base oil. Printing inks, adhesives and sealants, gear oils, oil extender polymers, process oil, metal working, and battery separators are just a few of the end-use uses for naphthenic base oil..

In this follow-up of last year’s STLE paper, we show how Naphthenic speciality wax-free base oils bring value to Hydraulic fluid formulations for low temperature application in aviation and mobile applications.

MaxNap naphthenic base oils offer high solvency, low pour points, and good color characteristics that are perfect for a wide range of applications including metalworking fluids, grease, adhesives, printing inks, and transformer oils.

Mar 13, 2023 · Calumet offers an extensive product line of naphthenic and paraffinic base oils that can meet your unique needs. Whether you’re looking for adhesives, compressor oils, gear oils, greases, insulating oils, paints and coatings, process oils or transformer oils, our quality-control measures ensure consistent uniformity and product performance.

Even though naphthenic oil is mineral-based, it is considered a Group V oil because it does not satisfy the API’s qualifications for Group I, II and III. The unique characteristics of naphthenic mineral oils have often made them good lubricants for locomotive engine oils, refrigerant oils, compressor oils, transformer oils and process oils.

Mar 15, 2023 · HYDROCAL™ products are naphthenic base oils produced exclusively by Calumet using a multi-stage hydrotreating process operating at pressures above 2500 psi. This process offers the unique ability to produce naphthenic base stocks that meet currently established performance standards as well as standards to be developed in the future.

Naphthenic base oil is a kind of group V base oil that is produced by hydro-treating sweet crude distillates at pressures exceeding 2500 psi. Low pour point, excellent liquidity, low wax, and low aromatic content characterize naphthenic base oil.

Naphthenic base oils outperform paraffinic oils in low-temperature conditions, making them ideal for hydraulic and automatic transmission fluid formulations. Their high solvency power also allows naphthenic oils to respond effectively to antioxidants and additives.

Jun 24, 2019 · Unlike paraffinics, naphthenics are obtained by refining naphthenic crudes, which contain more of the cyclic, saturated ring structures that are the main components of naphthenic base oils. Despite their low-temperature fluidity and ability to dissolve additives, their low V.I. and available viscosity grades can present limitations for ...
