- Chemical Name
- Dipropylene Glycol Dibenzoate
Velsiflex® 342 S is a blend of dipropylene glycol dibenzoate and other benzoate esters. It is a lower moisture / lower hydroxyl plasticizer. It has been widely used in 2K polyurethane systems to reduce cure interface, which also provides better rebound, improved tear strength and reduced swell with solvents. It is also used in many polysulfide sealant applications and has proven to be a very efficient ester from a softening agent perspective.
