Solvay launches new shortstop inhibitor solution for safer acrylic monomer transportation & storage in UAE


Formulated with non-toxic solvent, solution to stop runaway polymerization effectively and economically


UAE, July 26, 2021

Solvay, a global leader in materials, solutions and chemicals, announced the launch of  Phenothiazine LVT™ 2330, a next-generation shortstop inhibitor solution in UAE. The solution is designed to offer protection against runaway polymerization of acrylic and methacrylic acids, esters and other monomers in bulk storage facilities, transportation tanks and containers.


A runaway polymerization is potentially hazardous due to the reaction becoming uncontrollable and the heat that it produces may lead to a fire or an explosion or rupture of closed storage and transport containers. This uncontrolled polymerization can place people, property and the environment at significant risk.


“Solvay’s new Phenothiazine (PTZ) LVT 2330 comprises a 30 per cent active liquid solution of PTZ dissolved into Rhodiasolv Polarclean HSPsolvent, part of Solvay’s line of powerful, green solvents for industrial applications,” said Dave Vanzin, Technical Service & Development Manager at Solvay. “It was developed as an alternative to the use of N-Methyl-2-pyrrolidone (NMP) widely employed in the United States and the European Union as a solvent for shortstop inhibitors but considered a substance of very high concern (SVHC) under REACH regulations.”


Solvay’s Phenothiazine LVT™ 2330 is safer to handle than NMP-containing solutions and has a lower freezing point, which is highly advantageous for facilities and transport in colder climates.  Also, the high active PTZ concentration of Phenothiazine LVT 2330 permits deployment and storage of the efficient and economic shortstop in both large and small installations.


“We see a great market potential for this pioneering shortstop inhibitor with a non-toxic and non-volatile solvent for the acrylics markets of different regions across the world - including the Middle East - where chemical toxicity is of increasing concern to the industry and authorities,” said Lars Fischer, Worldwide Technical Market Manager at Solvay. “However, Asia offers the greatest potential where shortstop inhibitors were not standard and have only recently been more widely accepted and used to help reduce the risk of accidents.”
