Technical Datasheet | Supplied by Songwon
Dibutyltin 3-mercapto propionate. Acts as a heat stabilizer. Suppresses the softening point and impact strength of rigid vinyl products lowering because of the very good heat-stability. Provides very good initial color in rigid PVC. Must not use with the stabilizer containing a Pb or Cd on account of forming a black material. Used in completely transparent rigid, polymer blend, water-resistant and sulfide-resistant products.

Hansen Solubility Parameters

[17.2, 12.4, 5.6]
[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 SONGSTAB™ TM-300P. A practical determination of these HSP values would provide higher certainty. Learn More.
