产品叙述

TPS 20 is a pale yellow liquid. It has a very slight odor and does not contain any chlorinated impurity or unsatured hydrocarbon.

TPS 20 is soluble in mineral oils and synthetic base oils and most common solvents. It is insoluble in water.

TPS 20 is an extreme pressure additive for lubricants. TPS 20 does not corrode copper. Its tertiary dodecyl chain being extremely stable, TPS 20 is the most efficient dialkyl trisulfide.

TPS 20 is an additive for :

  • Neat and soluble cutting oils used with copper and copper alloys;
  • Cold rolling oils;
  • Gear oils and EP Greases.
