Dicumyl Peroxide (DCP) Supplier in Malaysia
- Also known as
- DCP Peroxide
- Bis(alpha,alpha-Dimethylbenzyl) Peroxide
- Bis(1-Methyl-1-Phenylethyl) Peroxide
Dicumyl peroxide (DCP), also called DCP peroxide, is an organic peroxide used as a crosslinking agent and free-radical initiator in rubber and polymer compounding. ChemTrade handles enquiries from Malaysian industrial buyers who need neat or predispersed dicumyl peroxide matched to a stated grade and process.
Commercial forms include high-assay neat crystals or powder at about 98-99% DCP, free-flowing granular material, and about 40% DCP masterbatch or predispersed grades on a polymer carrier. Neat and carrier forms are not interchangeable without checking active content and handling requirements.
Typical applications include EPDM and other rubber curing, polyethylene crosslinking, EVA foam, wire and cable compounds, and selected polymerisation initiation. Dicumyl peroxide is distinct from benzoyl peroxide, MEKP and dicalcium phosphate, so the full name or DCP peroxide should be used in specifications.
Send the required form, assay or active content, carrier if predispersed, application, quantity and delivery location with your enquiry. Availability, packing and documentation are confirmed with the quotation.

Dicumyl Peroxide 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 |
|---|---|---|---|---|
| Neat dicumyl peroxide 98-99% | crystals or free-flowing powder | about 98-99% DCP | High-assay organic peroxide for rubber and polymer crosslinking, EVA foam curing and selected polymerisation initiation where neat dicumyl peroxide is specified. | Confirm the required pack format with the quotation. |
| DCP 40% masterbatch / predispersed | predispersed granules or masterbatch on a polymer carrier | about 40% active DCP, carrier confirmed against the enquiry | Rubber-curative and polymer-compound form for safer handling and easier dispersion than neat crystals, especially in EPDM, polyethylene and EVA compounding lines. | Confirm the required pack format with the quotation. |
| Granular industrial dicumyl peroxide | free-flowing granules | — | Industrial charging where a free-flowing solid is preferred over fine powder and the active content is matched to the buyer specification. | Confirm the required pack format with the quotation. |

Common questions about dicumyl peroxide
What is dicumyl peroxide (DCP) used for?
Dicumyl peroxide is an organic peroxide used mainly as a crosslinking agent and free-radical initiator. Common applications include rubber curing (especially EPDM), polyethylene crosslinking, EVA foam, wire and cable compounds, and selected polymerisation processes.
Is neat dicumyl peroxide the same as a DCP 40% masterbatch?
No. Neat material is typically about 98-99% dicumyl peroxide as crystals or powder. A 40% masterbatch or predispersed grade carries the same active on a polymer carrier for easier dispersion and handling. State the required active content and carrier so the correct form can be quoted.
Does DCP mean dicalcium phosphate?
Not on this page. Here DCP means dicumyl peroxide, the organic peroxide crosslinker. Dicalcium phosphate is a different chemical and is not covered by this product. Always expand the acronym in enquiries and specifications.
Which details should I provide for a dicumyl peroxide quotation?
State neat or predispersed form, target assay or active content, carrier for masterbatch grades, polymer or rubber application, quantity, delivery location and any document needs. Include the current specification if the process already runs on a defined grade.
Can packing and documentation be confirmed with the quote?
Yes. List the preferred pack format and required product documents in the enquiry. Available packing and documentation are confirmed for the quoted grade.
Is dicumyl peroxide the same as benzoyl peroxide or MEKP?
No. Dicumyl peroxide, benzoyl peroxide and MEKP are different organic peroxides with different decomposition behaviour and end uses. Specify dicumyl peroxide or DCP peroxide by name and grade rather than a generic peroxide request.
