Ammonium Persulphate 98% Electronic Grade

Ammonium Persulphate 98% Electronic Grade (CAS 7727-54-0, molecular formula (NH4)2S2O8) is a process chemical for electronics and metal finishing, where trace metal content and particle contamination matter as much as headline assay. China Chemicals supplies it at 98% min 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 APS, Ammonium Peroxydisulphate, Diammonium Persulfate. 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

Copper etching of printed circuit boards
Micro-etch and surface roughening before plating
Polymerisation initiator for acrylic emulsions
Oxidiser in hair and textile bleach systems
Desizing agent in textile preparation
