Technical Data
Chemical name : Fatty acids C16-18 and C18-unsatd., Me esters, sulfurized
Common name : Polysulfides

Properties

Thanks to its polar head groups and fatty chains, Esterol18S improves lubricity and anti-wear properties, while extending extreme-pressure performances. Esterol18S is recommended for the formulation of neat and soluble metal working fluids (with a preference to yellow metals such as copper and alloys) as well as for industrial lubricants. Esterol18S can be formulated solely or in combination with other products within the TPS range (i.e. enhanced anti-wear & extreme-pressure properties in combination with TPS®20,TPS®32 or TPS®37LS). Esterol18S is produced from renewable vegetable raw materials and therefore, is the ideal alternative to sulfurized lards.
