Chemical nature:  Polymeric plasticizer derived from adipic acid and butanediol 

Palamoll® 646 is a slightly yellowish, practically anhydrous liquid and has a mild ester odour. It is soluble in the usual organic esters, ketons, ethers, aromatic and chlorinated hydrocarbons. The product is practically insoluble in water, aliphatic hydrocarbons, vegetable and animal oils. When Palamoll® 646 is mixed with monomeric plasticizers, a miscibility gap is observed, so that it is necessary to verify their suitability before use. Palamoll® 646 is listed for use in food-contact applications.
