Kalama® VITROFLEX® A99 Benzoate Plasticizer

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

Kalama VITROFLEX A99 is a high-value offering for the A-side of polysulfide sealants. It offers similar benefits to Kalama VITROFLEX A90, including exceptional permanence, low migration, and low fogging. In addition, it maximizes purity to meet the highest performance requirements, such as exceptionally low odor.

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