Potassium Persulfate Supplier in Malaysia
- Also known as
- Potassium Persulphate
- Potassium Peroxodisulfate
- Potassium Peroxydisulfate
- KPS
Potassium persulfate supplier for polymer, cosmetic, electronics and process buyers in Malaysia. Also written potassium persulphate and listed as potassium peroxodisulfate, potassium peroxydisulfate or KPS, it is a white crystalline solid and a strong oxidiser. It is the least water-soluble of the three commercial persulfate salts, which is why formulators choose it for dry blends.
Technical grade is the general industrial material, commonly specified near 99 per cent minimum assay, and is offered as crystalline powder or free-flowing granules. A cosmetic or bleach booster grade covers powder hair-lightening formulations. Buyers select on assay, active oxygen content, particle size and moisture.
Emulsion polymerisation plants use potassium persulfate to initiate acrylic, styrene-acrylic, vinyl acetate, PVC and SBR systems, thermally or in a redox pair. Circuit board and metal finishing lines use it for copper micro-etch and surface cleaning. Textile mills, well-service blends and laboratories take it as an oxidiser for desizing, gel breaking and persulfate oxidation methods.

Potassium Persulfate grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Technical grade potassium persulfate | white crystalline powder | typically ≥ 99% K2S2O8 for technical material | General industrial duty as a polymerisation initiator and oxidising agent, including acrylic, styrene-acrylic and vinyl acetate emulsion systems. | Confirm the required pack format with the quotation. |
| Granular potassium persulfate | free flowing white granules | — | Dry powder blends and dosing systems that need a low-dust, free-flowing particle size rather than fine crystalline material. | Confirm the required pack format with the quotation. |
| Cosmetic or bleach booster grade | white crystalline powder | — | Powder hair bleach and lightening formulations where potassium persulfate is the oxidiser and a cosmetic-suitable specification is requested. | Confirm the required pack format with the quotation. |
| Etching and surface cleaning grade | white crystals or granules | — | Copper micro-etch, printed circuit board etching and metal surface cleaning baths that call for a controlled-purity persulfate salt. | Confirm the required pack format with the quotation. |

Potassium Persulfate applications
Safety and handling
Store sealed in a cool, dry, well ventilated place away from heat, moisture, combustible material and reducing agents. Persulfates are strong oxidisers and lose activity if they take up water, so keep packs closed and stock rotated. Control dust during handling and follow the safety information issued for the quoted grade. Supply is subject to applicable requirements.
Common questions about potassium persulfate
Is potassium persulfate the same as potassium persulphate?
Yes. One salt, two spellings: datasheets usually write persulfate and local trade writes persulphate. Potassium peroxodisulfate, potassium peroxydisulfate and KPS name the same material.
How does potassium persulfate compare with the ammonium and sodium salts?
All three release the same oxidising persulfate ion, but the cation changes solubility and residue. Potassium persulfate is the least soluble of the three, which is why formulators pick it for dry powder blends that must resist caking. Order the salt your formulation specifies.
Why is potassium persulfate chosen for powder hair bleach?
Its low water solubility and stable crystalline form suit dry blends that sit on shelf before use, and it releases active oxygen once mixed with the developer. Ask for a cosmetic-suitable specification when that is the duty.
What assay and particle size should an enquiry state?
State the minimum assay or active oxygen content required, whether powder or granular material is wanted, and any moisture or heavy-metal limits. Add the dosing method if particle size matters to your process.
Can potassium persulfate be used as a polymerisation initiator?
Yes. It decomposes thermally to give sulphate radicals at normal emulsion polymerisation temperatures, and it is also run in a redox pair for lower-temperature or delayed initiation.
What details are needed for a potassium persulfate price enquiry?
Provide grade, assay or active oxygen requirement, particle form, quantity and delivery location, and note whether the use is polymerisation, bleach blending, etching or laboratory work.
