Benefos® 1618

Technical Datasheet | Supplied by Mayzo
HSP Distance with AXION® 5021: 2.5
Benefos®1618 by Mayzo is 2,4,8,10-Tetraoxa-3,9-diphosphaspiro[5.5]undecane, 3,9-bis(octadecyloxy). Acts as an antioxidant. It also contributes to the UV stability of polyolefins. Helps prevent discoloration of polymers during extrusion and molding operations, exhibits high performance at low loading levels, reduces discoloration in polymers containing pigments such as titanium dioxide, enhances the light stability of polyolefins when used with light stabilizers, is non-discoloring and shows low volatility, FDA cleared for use in olefin polymers, EVA, and polystyrene. Benefos®1618 by Mayzo is compatible with polyolefins, polyesters, styrenic polymers, engineering plastics, elastomers. It has a shelf life of 2 years. Recommended dosage is 0.05-0.5% depending on the substrate, processing conditions, and other performance requirements.

Hansen Solubility Parameters

[14, 0.1, 0.3]
[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 Benefos® 1618. A practical determination of these HSP values would provide higher certainty. Learn More.
