VPS®17

Product

VPS®17 is an active sulfur donor additive made of vegetable sulfurized esters (17% sulfur) compatible with mineral, synthetic base oils and greases.

 

Key properties: low color & odor, limpid, bio-based and bio-degradable.

Identity

CAS number
68390-93-2
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, VPS®17 improves lubricity and anti-wear properties, while extending extreme-pressure performances without corroding copper alloys. VPS®17 is recommended for the formulation of neat and soluble metal working fluids (with a preference to yellow metals such as alloys) as well as for industrial lubricants. VPS®17 can be formulated solely or in combination with other products within the TPS range (i.e. enhanced anti-wear and extreme-pressure properties in combination with TPS®32 or TPS®37LS). VPS®17 is produced from renewable vegetable raw materials, is poorly odorous and colored and therefore, is the ideal alternative to sulfurized lards.
