Polyethyleneimine Supplier in Malaysia for PEI Grades
- Also known as
- PEI
- Polyaziridine
- Aziridine Homopolymer
Polyethyleneimine supplier for pulp and paper, water-treatment, textile, coating and formulation buyers in Malaysia. Commonly abbreviated PEI and also called polyaziridine, this amine-rich polymer is selected for its cationic character, adhesion and surface-modification behaviour.
Branched and linear polyethyleneimine have different chain architectures and should be specified separately. Commercial requirements may call for a viscous polymer, an aqueous solution at a defined solids content or a solid form, depending on molecular grade and the receiving process.
PEI is used as a drainage, retention and fixative aid in paper production, a coagulant or flocculation aid in water processes, a dye fixative in textiles and an adhesion promoter in coatings, inks and adhesives. Grade selection considers architecture, molecular-weight range, solids, viscosity, pH and compatibility.
Send the required architecture, molecular grade, form or concentration, application, quantity and delivery location with your enquiry. Packing, available technical documentation, quotation validity and delivery timing are confirmed for the offered grade.

Polyethyleneimine 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 |
|---|---|---|---|---|
| Branched polyethyleneimine | clear to pale yellow viscous liquid or aqueous solution according to molecular grade | — | Adhesion promotion, paper drainage and retention, dye fixation, water-process treatment and chemical modification where a highly functional cationic polymer is required. | The concentration and pack format are confirmed with the quotation. |
| Linear polyethyleneimine | solid or solution prepared to the stated molecular grade | — | Speciality polymer modification, coatings, membranes and research-led formulations that specifically require a linear rather than branched PEI architecture. | The physical form and pack format are confirmed with the quotation. |
| Aqueous polyethyleneimine solution | clear to pale yellow viscous aqueous liquid at a specified solids content | — | Metered addition to pulp and paper, water-treatment, textile, coating and adhesive processes where a defined solution concentration supports dosing. | The solution pack format is confirmed with the quotation. |

Common questions about Polyethyleneimine
What does PEI mean in a polyethyleneimine specification?
PEI is the common abbreviation for polyethyleneimine, also called polyaziridine. Because PEI can also be used for unrelated polymer names in some contexts, the enquiry should state polyethyleneimine and CAS 9002-98-6.
What is the difference between branched and linear polyethyleneimine?
Branched PEI contains primary, secondary and tertiary amine sites in a highly branched structure, while linear PEI has a different chain architecture. Their solubility, viscosity, reactivity and formulation behaviour differ, so the architecture must be specified.
Should polyethyleneimine be ordered neat or as an aqueous solution?
The choice depends on the molecular grade and the receiving process. Aqueous solution supports pumping and metered dosing, while another form may suit polymer modification or specialised formulation work. State the target solids content and dosing setup with the enquiry.
How is PEI selected for pulp and paper or water treatment?
Selection usually considers polymer architecture, molecular-weight range, solids content, viscosity, pH and the charge demand of the process stream. Include the furnish or wastewater type and the intended drainage, retention, fixation or separation duty.
Can polyethyleneimine be used as an adhesion promoter?
PEI is used in selected primers, coatings, inks and adhesive systems to modify surfaces and improve adhesion. Suitability depends on the substrate, resin system, curing conditions and the selected architecture or molecular grade.
What details are needed for a Polyethyleneimine quotation?
Provide branched or linear architecture, molecular-weight range, physical form or solution concentration, specification, application, quantity and delivery location. Add packing and technical-document requirements for confirmation with the quotation.
