As an excellent flame retardant supplier, we have solutions for many different fire safety needs. Based on ammonium polyphosphate, our Exolit® AP line offers cutting-edge flame retardant additives and intumescent systems. The Exolit® EP line provides special liquid solutions for epoxy resins. Our organophosphorus solutions from the Exolit® OP line are environmentally friendly products that can enhance the fire safety of many engineering plastics. Exolit® VF facilitates use with viscose fibers, Exolit® RP handling of red phosphorus. And those who order flame retardants from us can also select from a wide variety of phosphate esters and other phosphorus chemicals, as for example for cleaning applications.
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. Ammonium Polyphosphate APP
