DIBUTYL MALEATE- ▸ Plasticizer: Flexibilizer for polymer compounds.
- ▸ Reactive comonomer: Internally plasticizes emulsion (e.g., vinyl) copolymers.
- ▸ Intermediate: Surface-active and specialty-chemical building block.
A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Dibutyl maleate (DBM, CAS 105-76-0) is the dibutyl ester of maleic acid, an unsaturated diester used as a plasticizer and as an internally plasticizing comonomer in emulsion polymers. The reactive double bond lets it copolymerize into vinyl and acrylic systems while contributing flexibility. It also functions as a surface-active intermediate.
Frequently Asked Questions
What is dibutyl maleate used for?
Dibutyl maleate (DBM, CAS 105-76-0) is the dibutyl ester of maleic acid. It is used as a plasticizer and, because of its reactive double bond, as an internally plasticizing comonomer that copolymerizes into vinyl and acrylic emulsion systems. It also serves as a surface-active specialty intermediate.
Why is dibutyl maleate used as a reactive comonomer?
DBM is an unsaturated diester whose carbon-carbon double bond lets it copolymerize directly into vinyl and acrylic polymers. Built into the backbone, it internally plasticizes the copolymer and contributes flexibility without the migration risk of an external plasticizer.
Is dibutyl maleate the same as dibutyl phthalate?
No. Dibutyl maleate (CAS 105-76-0) is an unsaturated maleate diester, while dibutyl phthalate (CAS 84-74-2) is a saturated ortho-phthalate ester. They have different chemistries and reactivity and are not interchangeable; specify by CAS.
What is the CAS number, formula, and HS code for dibutyl maleate?
DBM is CAS 105-76-0, molecular formula C12H20O4, in the esters family. HS code 2917.19 (polycarboxylic acids and their ester derivatives, other acyclic).
What is the cost of bulk dibutyl maleate?
Bulk pricing depends on volume, packaging (drums, IBCs), and destination. Send your required quantity and ship-to details for a current quote; each shipment ships with a CoA and SDS.
