TPS® 20 is an inactive trisulfide sulfur donor additive (20% sulfur) showing excellent extreme-pressure and anti-wear properties, practically non-corrosive to copper & compatibility with mineral, synthetic base oils and greases
Key properties: virtually colorless and odorless, clear liquid, with no particulates, free of unsatured hydrocarbon residues and easily emulsified in emulsions and semi-synthetic fluids.
Common name : Polysulfides
TPS® 20 is suitable for working with copper alloys, gear oil formulations and soluble oil formulations for cold-rolling. TPS® 20 is odorless, almost colorless and shows excellent thermal stability making it the best choice for rolling oils. In addition, TPS® 20 is fully compatible (no chemical degradation) with emulsifier-type concentrates used in the formulations of emulsion or micro-emulsion.
