TPS® 32 is an active pentasulfide sulfur donor additive (32% sulfur) showing excellent extreme pressure performances & compatibility with mineral, synthetic base oils and greases.
Key properties: virtually colorless & odorless, clear liquid, with no particulates, free of unsatured hydrocarbon residues & compatible with a large range of formulations.
Common name : Polysulfides
TPS® 32 exhibits a high active sulfur content readily available even at low temperatures, which in addition to its excellent chemical stability, makes it particularly suitable for highly demanding applications with steel. TPS® 32 shows lighter color and lower odor than sulfurized olefins.
