Public announcement regarding Solvay-Hengchang (Zhangjiagang)’s 2000t/a phosphorus-based flame retardant project: Recently, information about Solvay-Hengchang (Zhangjiagang) Fine Chemicals Co., Ltd.’s 2000t/a phosphorus-based flame retardant project was made public on relevant websites. This project plans to invest 9.8 million yuan in converting an existing parts warehouse on the factory site into a production workshop covering 270 square meters (with a steel structure), and in purchasing 15 sets of new production and auxiliary equipment, in order to carry out a technical upgrade project for the production of 2,000 tons per year of phosphorus-based flame retardants. Product plan: This technical upgrade aims to reduce the current production capacity of calcium phosphate by 2,000 tons per year; the filter cake used in the production of calcium phosphate will be utilized as a raw material together with amine-based materials to produce phosphorus-based flame retardants with high added value. Based on the process principles and material balance of the technical improvement project and its related products (sodium hypophosphite, calcium phosphate), after the improvements, the amount of filter cake fed into the calcium phosphate production unit is reduced by 3,184.56 tons per year, allowing for a reduction in calcium phosphate production by 2,000 tons per year ； 1345.71t/a filter cake phosphorus-removing flame retardant production plant, with a capacity of 2000t/a.
