SN350 Mineral Base Oil
SN350 is a mineral base oil grade with a medium viscosity profile, considered as a raw-material option for selected industrial and lubricant formulations. Selection depends on the target finished product, additive system and the buyer's technical specification.

What is SN350 base oil?
SN350 is a commercial base oil grade rather than a ready-to-use engine, hydraulic or gear oil. Finished lubricants are typically formulated from one or more suitable base stocks and, where needed, performance additives. The commercial grade name alone cannot establish suitability for a particular application or determine the full quality classification of a specific batch.
Compared with the generally higher-viscosity SN500 class, SN350 offers a different flow profile. Manufacturers should assess actual batch data against their intended blend before approving a material.
Potential applications
Industrial lubricants: May be evaluated as a blending component for suitable machinery and circulating oil formulations.
Hydraulic fluids: May be considered where the finished formulation can meet viscosity, anti-wear, oxidation, air release and other performance requirements. Grade designation alone does not guarantee suitability.
Metalworking fluids: May be assessed for selected mineral-oil-based cutting or process fluids; emulsification and additive compatibility must be established separately.
General mineral-oil formulations: May be used in appropriate formulations following technical assessment and, where applicable, pilot blending and testing.
Technical purchasing criteria
Key parameters include kinematic viscosity at 40°C and 100°C, viscosity index, flash point, pour point, density, sulphur, water content and any requirements specific to the intended end use. Viscosity index describes the sensitivity of kinematic viscosity to temperature change; it does not independently establish all performance properties.
| Technical parameter | Why it matters |
|---|---|
| Kinematic viscosity at 40°C | Helps describe flow behaviour under operating and blending conditions. |
| Kinematic viscosity at 100°C | Relevant to temperature-dependent flow behaviour and blend calculations. |
| Viscosity index (VI) | Indicates how sensitive viscosity is to temperature change. |
| Flash point | Considered in handling, process and product safety assessments. |
| Pour point | Provides a preliminary view of low-temperature behaviour. |
| Density, colour, sulphur, water | May be checked against the manufacturer's specification and quality monitoring. |

SN350 FAQ
- Is SN350 a finished lubricant?
- No. It is a base oil for formulation and further processing.
- How does SN350 differ from SN500?
- SN500 generally has a higher viscosity profile. Selection depends on the target formula and verified specifications.
- Can SN350 be used in every hydraulic formulation?
- No. The finished lubricant must meet the required performance and compatibility criteria.
- Can I request a sample?
- You can submit a request; availability and conditions will be confirmed as part of the technical review.
- How is bulk pricing determined?
- By product, quantity, delivery destination and agreed commercial terms.
