Jayflex™ DIUP

Technical Datasheet | Supplied by ExxonMobil
Jayflex™ DIUP by ExxonMobil Chemical is a high-molecular-weight plasticizer designed to provide good performance at high temperatures and good outdoor-weathering capabilities. It is compatible with flexible PVC products that require a low contribution to fogging. Due to its higher molecular weight than DIDP and DINP, it contributes to increased permanency. Jayflex™ DIUP exhibits lower density than DIDP and DINP, enabling higher output volumes at the same weight, sustained flexibility in cold conditions, low volatility for resistance to heat-aging conditions, slower migration and increased extraction resistance compared with Jayflex™ DIDP. It is not carcinogenic, mutagenic or toxic. It is REACH compliant.

Hansen Solubility Parameters

[16.3, 4.3, 2.1]
[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 Jayflex™ DIUP. A practical determination of these HSP values would provide higher certainty. Learn More.
