The production process
OF EXOLIT® OP

The reaction of the gas ethylene with a dissolved phosphorus-containing salt leads to the salt sodium diethylphosphinate. The final product DEPAL – the basic ingredient of Exolit® OP formulations – is formed by mixing with an aluminum salt. DEPAL is then filtered off and dried.
