Citroflex® is a range of plasticizers from Vertellus that are based on citric acid esters and suitable for use in a variety of applications and polymer systems.
Citroflex® provides a wide range of performance benefits but primarily used as plasticizers in aqueous- and solvent-based polymers, including acrylics, cellulosic polymers, vinyl acetates, vinyl, and urethane polymer systems. Citroflex® is available in both hydrophilic and lipophilic esters, which give formulators control over the polymer system characteristics to better suit the needs of the finished product.
Phthalate plasticizers, including DEHP, have been the primary plasticizers used in PVC-based products for many years. Citroflex® plasticizers are excellent alternatives to phthalate-based plasticizers as they provide a better balance of physical properties and low volatility when used in PVC systems.
Citroflex® offers high tensile strength and elongation with reduced volatility and plasticizer's migration rate of the plasticizer. Citroflex® is the ideal plasticizer choice for use in the following applications:
Food packaging films and plastics
Vinyl resins used in toys
Plastic tubes for medical devices and applications
