Chemical name : Polysulfides di-tert-dodecyl
Common name : Polysulfides
Properties
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.
