Citroflex™ A-4 Plasticizer (Acetyl Tributyl Citrate)
Our Citroflex™ esters are based on natural citric acid raw material, which is mainly derived from the fermentation of corn. The esters have a long history of use in food and beverage, flavoring, medical, and pharmaceutical applications.
Citroflex™ A-4, also called Acetyltri-n-butyl Citrate (ATBC), is widely used in children’s toys and food contact applications. It 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 is effective in solution coating both paperboard and foil. It is an excellent plasticizer for vinyl toys.
Citroflex™ A-4 is also used as plasticizer for bioplastics such as a poly lactic acid, cellulose acetate, and poly hydroxyalkanoic acid.
