Emerald Kalama Chemical


Kalama® VITROFLEX® non-phthalate, benzoate plasticisers have excellent safety and regulatory profiles for polysulphides. They enable formulators to eliminate plasticisers facing scrutiny and regulatory pressure, such as benzyl phthalate and chlorinated paraffins. Because Kalama VITROFLEX Plasticisers have been expressly designed for polysulphides, they also offer excellent performance characteristics, compatibility, and value in this application.

Kalama VITROFLEX B enables formulators to achieve desirable characteristics in the B-side of polysulphide sealants. These include: faster hardness development, improved lap shear strength, excellent flexibility and adhesion, non-settling (high viscosity stabilization), and equivalent pot life to other common plasticisers.

Emerald offers solutions for both the “A” (polymer) and “B” (catalyst) sides of two-part polysulphide sealants. These products are manufactured in Europe, offering an excellent supply chain to serve EMEA customers. Additional solutions for this application include Kalama VITROFLEX A99 and Kalama VITROFLEX A90.
