Overview
Aurorium Citroflex™ A-4 citrate plasticizer provides many improvements over di-butyl phthalate in cellulose nitrate films, including lower volatility, better resistance to yellowing, and better adhesion to metals.
Citroflex™ A-4 citrate additives are effective in solution coating for both paperboard and foil. Citroflex™ A-4 citric acid esters are also used as plasticizers for bioplastics such as polylactic acid, cellulose acetate, and poly hydroxyalkanoic acid. The citric acid esters with lower molecular weight (Citroflex™ C-2, A-2, C-4, and A-4) have plasticization characteristics like those of the lower molecular weight phthalates, adipates, and sebacates in a variety of polymers.
