TBPB

Technical Datasheet | Supplied by United Initiators
Tert.butylperoxybenzoate. It acts as an initiator (radical source) in the polymerization of monomers, e.g. ethylene, styrene in mass or suspension, (meth-)acrylates, allyl monomers in combination with other stable peroxides to achieve a constant rate of polymerization over the entire reaction. At low temperatures and under high pressure, however, highly concentrated solutions can cause crystal precipitation in dosing pumps. Provides particular advantage of reducing the residual monomer content. It is highly efficient and appears as a mobile yellowish liquid which is readily miscible with high-boiling aliphatic hydrocarbons.

Hansen Solubility Parameters

[16.9, 6.9, 6.2]
?
[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 TBPB. A practical determination of these HSP values would provide higher certainty.
