Description
Calcium Hypochlorite 70% Granular
Calcium Hypochlorite 70% Granular (CAS 7778-54-3, molecular formula Ca(ClO)2) is a treatment chemical specified by municipal and industrial plant operators where dose consistency and impurity control directly affect finished water quality. China Chemicals supplies it at 70% available chlorine in pack sizes from 1 kg through to 500 kg Pallet, so laboratory trial quantities and full production volumes can be sourced from the same specification.
It is also traded as Cal Hypo, HTH, Bleaching Powder. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.
Typical applications
- Swimming pool shock chlorination
- Emergency and remote potable water disinfection
- Sanitisation of food processing surfaces
