Plasticizers and Coalescents

K-FLEX® and VITROFLEX™ plasticizers, coalescents, and modifiers are optimized for excellent value, performance, compatibility, and economy in a wide range of applications. They are non-phthalate, low-VOC, and have positive attributes from a product health, safety, and environmental perspective compared to many other options.  


In addition to the environmental attributes these products offer, they can also enhance key performance characteristics of the end-product, meeting or exceeding the performance of other standard plasticizers and coalescents in a wide range of applications, including adhesives, caulks, sealants, coatings, and vinyl/plastisols. Many products in the line also have certain FDA clearances for use in indirect food-contact applications.


Emerald is a reliable global supplier, with manufacturing in the U.S. and Europe.
