Roadmap to reliability
With 50 years’ experience of perfecting naphthenic base oils, Nynas offers a sustainable, high-performance alternative as Group I supply tightens. Our broad portfolio of naphthenic grades and Group II/naphthenic blends are not just replacements – they are an upgrade.
Greases – Efficiency in Every Step
Nynas naphthenic base oils improve grease production by reducing thickener use and cooking temperatures, cutting energy costs. Their superior oil-soap interaction lowers bleeding and extends product shelf life, while excellent low-temperature flow ensures reliable performance across applications. With a broad product range, there's a perfect match for every formulation.
The power of naphthenics
Nynas naphthenic base oils bring a unique combination of properties that make them ideal in a wide range of demanding industrial applications.
Superior Solvency
Dissolves more additives than paraffinics, improving formulation flexibility. Low Aniline Point = High Solvency.
Excellent Low-Temperature Performance
Keeps fluids flowing in Arctic and aviation-grade conditions. Pour points as low as <-70°C.
Low Toxicity
IP 346 label-free and low in PAHs. Safer for people and the planet.
Efficient Heat Transfer
Improves cooling and thermal control. Ideal for shock absorbers and compressors.
Wide Viscosity Range
From 3 to 700 cSt @ 40°C – perfect for tailored formulations. From spindle oils to greases.
Metalworking Fluids – Additive-Friendly, Emulsion-Ready
Thanks to their high solvency, Nynas oils dissolve and stabilise complex additive packages, making them ideal for modern semi-synthetic metalworking fluids. Their emulsion stability and high density also enhance performance in central systems, while efficient cooling extends tool life and reduces downtime.
Metal Forming Fluids – Handling the Pressure
In demanding forming operations, Nynas naphthenic oils deliver high additive solubility and formulation flexibility. Their strong thermal properties ensure effective cooling under extreme pressure, while stable emulsions contribute to smooth operations and less waste.
Industrial Lubricants – Precision, Protection, Performance
Nynas base oils are used alone or in blends for a variety of industrial lubricants. They offer excellent additive solubility, help control deposits and improve seal compatibility. With viscosities ranging from light to heavy, they support everything from aviation hydraulics to gear oils.
Refrigeration Oils – Clean, Cold, and Consistent
Our Nyfrost grades are hydrotreated naphthenic base oils specially developed for refrigeration compressors. Available in ISO VG 32, 46, 68, and 100, they offer a low floc point, excellent refrigerant compatibility, and clean, depositfree performance with ammonia, hydrocarbons, and CFCs.

NYNAS S 90 / NS 100 / T 110 / BT 150
- High viscosity grades with varying solvency profiles
- T 110 / BT 150 = optimised solvency, S 90 = optimised refining degree hence lower solvency
- Up to 28°C lower Aniline Point vs. paraffinics (SN 500), enabling better additive solubility, improved emulsion formation, enhanced grease production

NYNAS T 400 / BT 400
- Very high-viscosity naphthenic bright stock
- Exceptional solvency compared to Group I SN 2500 (Aniline Point approximately 28°C lower)
- Ideal for grease manufacturing, high-viscosity industrial lubricants, metalforming emulsions (e.g., tube drawing)
