TDI Supplier in Malaysia for Polyurethane Systems
- Also known as
- Toluene Diisocyanate
TDI supplier in Malaysia for flexible foam, polyurethane elastomer, coating and adhesive manufacturers. TDI is the standard abbreviation for toluene diisocyanate, a reactive aromatic isocyanate raw material selected by isomer profile, NCO requirement and the impurity limits of the formulation.
Commercial requirements commonly distinguish mixed-isomer TDI used in flexible slabstock and moulded foam from grades with a higher 2,4-isomer proportion for selected elastomer, coating, adhesive and prepolymer routes. This page covers the TDI raw material, not reacted prepolymers, MDI or polymeric MDI.
Major applications include cushioning and bedding foam, automotive seating, moulded flexible foam and polyurethane systems for industrial rollers, wheels, coatings and adhesives. Grade selection must follow the buyer's polyol system, process conditions and finished-product target rather than the end use alone.
Send the required TDI isomer profile or current grade code, specification, application, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation.
- Grade
- mixed-isomer, 2,4-isomer-rich
- Appearance
- clear to pale-yellow reactive liquid for common commercial grades, with physical behaviour depending on isomer profile and temperature
TDI 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 |
|---|---|---|---|---|
| Mixed-isomer TDI for flexible foam | clear to pale-yellow liquid | — | Slabstock and moulded flexible polyurethane foam for cushioning, seating and related applications where the formulator specifies the TDI isomer profile and impurity limits. | Confirm the required pack format with the quotation. |
| Higher 2,4-isomer TDI grade | liquid or low-melting material depending on temperature | — | Polyurethane elastomer, coating, adhesive and prepolymer manufacture where a higher proportion of the 2,4-isomer and a controlled reactivity profile are required by the formulation. | Confirm the required pack format and handling form with the quotation. |

Safety and handling
Keep TDI sealed, dry and protected from moisture, contamination and unsuitable temperatures. Handle reactive isocyanates using the safety information for the quoted grade and supply form. Supply is subject to applicable requirements.
Common questions about TDI
What does TDI stand for?
TDI is the standard abbreviation for toluene diisocyanate, an aromatic diisocyanate raw material used in polyurethane manufacture. Commercial TDI grades are selected by isomer profile and process-sensitive impurity limits.
Is TDI the same as MDI or polymeric MDI?
No. TDI, monomeric MDI and polymeric MDI are different aromatic isocyanate families with different structures, commercial grades and processing behaviour. Use the exact isocyanate named by the polyurethane formulation.
Which TDI grade is used for flexible polyurethane foam?
Flexible slabstock and moulded foam commonly use a mixed-isomer TDI grade matched to the polyol system and production process. State the current grade code, required isomer profile and any NCO, acidity, colour or impurity limits.
Is a TDI prepolymer covered by this page?
No. A TDI prepolymer is a reacted material made by combining TDI with a specified polyol or other hydroxyl-functional component. This page covers the TDI raw material; prepolymers need their own NCO, viscosity and backbone specification.
Why must TDI be protected from moisture?
Isocyanate groups react with water, which can change product quality, generate gas and disrupt polyurethane processing. Keep transfer and storage systems dry and follow the handling information supplied for the quoted grade.
What information is needed for a TDI price enquiry in Malaysia?
Provide the isomer profile or current grade code, specification, foam or other polyurethane application, quantity and delivery location. State any packing and document requirements so they can be confirmed with the quotation.
