Duralink™ HTS

Duralink™ HTS by Eastman is hexamethylene-1,6-bis(thiosulfate), disodium salt, dehydrate. Acts as a vulcanizing agent & adhesion promoter. It is used in sulfur-based vulcanization systems to generate hybrid crosslinks which provide increased retention of physical and dynamic properties when exposed to anaerobic conditions at elevated temperatures such as those experienced during over-cure, when using high curing temperatures or during product service life. It is non-staining and non-discoloring in most compounds. Duralink™ HTS is compatible with NR, IR, SBR, BR and blends of these polymers. Recommended dosage is 1-2 phr.

Hansen Solubility Parameters

[19.6, 19.6, 23.9]
[δD - Dispersion force interactions, δP - Polar force interactions, δH - Hydrogen bond force interactions]

Please note, these HSP values are estimations. It is based upon the “like seeks like” principle. It splits an ingredients interactions into three parameters; δD (Dispersion force interactions), δP (Polar forces interactions) and δH (Hydrogen bond force interactions). Hansen Solubility Parameters can help you find a wide range of products that are predicted to be compatible with Duralink™ HTS. A practical determination of these HSP values would provide higher certainty. Learn More.
