NiMAC Ltd offers a range of sodium and calcium sulphonates. Please follow the link below to our main website for product advice and contact information.

Sodium Sulphonates

Sodium sulphonates are often the key raw material of many metalworking fluid formulations with traditionally a molecular weight of between 390-550MW being utilised as a combined emulsifier and corrosion inhibitor.

Sodium sulphonates combine both emulsification and corrosion resistance properties within the same molecule. They are available in a range of molecular weights with the corrosion resistance increasing and the emulsification properties decreasing as the molecular weight increases.

Sulphonates with a higher molecular weight are highly effective corrosion inhibitors especially when based on the non water soluble cations of calcium, barium and magnesium.

For motor oil and fuel additives sodium sulphonates are often converted to calcium or barium salts; though in some situations the sodium sulphonates may be preferred. When it is used as an additive in motor oils, detergency and rust inhibitive properties are the most important functions.

Sodium sulphonates can be classified as either naturally derived sulphonates or synthetically manufactured sulphonates dependent on whether they were produced during the production of white oil or by the sulphonation of alkylates.

Calcium Sulphonates

Calcium sulphonates are also available in different molecular and offer excellent corrosion protection, demulsification and EP properties.

Calcium sulphonates can be either neutral, slightly basic or highly over based (TBN300-400). Typically the 300TBN calcium sulphonates have a higher sulphonate content and a lower carbonate content than the 400TBN calcium sulphonates. The sulphonate content provides for corrosion inhibition whilst the carbonate content principally provides for acidity regulation.

Neutral calcium sulphonates are recommended for use in corrosion inhibitors, hydraulic oils, and turbine oils where they impart corrosion inhibition and demulsification.

Overbased calcium sulphonates with a TBN of between 300-400 are used in industrial, marine and crankcase oils. When used in conjunction with sulphurised EP additives they can activate the sulphur.

NiMAC Ltd has a range of sulphonates, corrosion inhibitors and emulsifier packages. We have the expertise to offer you advice on components or offer you bespoke solutions and as such we would welcome your enquiry.
