Description
Potassium Hydroxide Flakes 90%
Potassium Hydroxide Flakes 90% (CAS 1310-58-3, molecular formula KOH) is a core commodity reagent used wherever reliable acid or alkali strength matters — from surface treatment and pH correction to downstream salt manufacture. China Chemicals supplies it at 90% min in pack sizes from 1 kg through to 1000 kg Bulk Bag, so laboratory trial quantities and full production volumes can be sourced from the same specification.
It is also traded as Caustic Potash, Potassium Hydrate, KOH Flakes. 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
- Liquid soap and potassium soap manufacture
- Biodiesel transesterification catalyst
- Alkaline battery electrolyte
- Potassium salt and fertiliser production
- Electroplating and metal surface treatment
