How does calcium hypochlorite fit into China's chlor-alkali industry value chain?
Calcium hypochlorite is a downstream inorganic chlorine product within China's chlor-alkali sector, which centers on caustic soda, chlorine, and hydrogen. Chlorine feeds PVC at roughly 40% of consumption, while inorganic chlorine derivatives like bleaching powder serve water treatment, paper, textiles, and metallurgy. Historically, Tianyuan Electrochemical Works, founded by Wu Yunchu in 1929, produced bleaching powder alongside hydrochloric acid and caustic soda, marking early domestic capacity. Today, producers integrate calcium hypochlorite into chlor-alkali complexes to monetize chlorine beyond PVC, especially when PVC margins weaken. Production economics hinge on chlorine availability and electricity costs, making calcium hypochlorite a flexible outlet for balancing chlor-alkali plant output.
