Technical & procurement detail
Functional role of tdi (toluene diisocyanate)+
TDI's reactivity profile and low viscosity suit flexible slabstock and moulded foam production, where processing latitude and cell structure control matter more than the mechanical strength that MDI systems deliver. It is also the base of many polyurethane prepolymers and coating hardeners.
Selecting the right grade+
The isomer ratio is the defining specification and directly affects reactivity and foam behaviour; NCO content and any prepolymer modification follow. Foam type, machine configuration and formulation determine what is quoted, and handling controls are reviewed as part of the enquiry.
Documentation and specification+
Properties differ between producers and between grades of the same material. Allzone confirms the applicable grade with the supplier before quoting and shares the technical data sheet and safety data sheet for the exact material offered, so the values you evaluate are the values you receive.
Frequently asked questions
Which TDI isomer ratio is standard?+
Different ratios are supplied for different foam systems and are not interchangeable. State the foam or system you run and the correct ratio is confirmed with the supplier before quotation.
Which grade will I be quoted?+
The grade is set by your specification. Share the target performance, process conditions and any customer or regulatory requirement in the RFQ and the matching grade is confirmed with the supplier before quotation.
What packaging is available?+
Packaging is confirmed with the supplier at quotation for the grade and quantity discussed.
Can you deliver across Ontario and Quebec?+
Yes. LTL and FTL freight is arranged across Ontario, Quebec and Western Canada, with container-direct supply for repeat volumes.
