Citroflex® Plasticizers for Flexible PVC

What is Citroflex®?

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.

Citroflex® in PVC Applications:

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
