Introduction
Toluene diisocyanate (TDI) is an aromatic diisocyanate that is a clear, pale yellow liquid with a
sharp, pungent odor, which is insoluble in water and miscible with most common organic solvents.
TDI (CAS No. 26471-62-5) consists of two isomers:
toluene-2,4-diisocyanate (2,4-TDI) (CAS No. 584- 84-9) and toluene-2,6-diisocyanate (2,6-TDI)
(CAS No. 91- 08-7), which is commercially produced in different ratios. The most common ratio
is 80% 2,4-TDI/20% 2,6 TDI. TDI is widely used and accounted for 34% of the global isocyanate

Application
TDI (toluene diisocyanate) is a kind of commonly used polyisocyanate, which is
polyurethane (PU) material and important basic raw material. It is mainly used for producing
flexible polyurethane foam and polyurethane elastomers, coatings, adhesives and so on.
Storage: sealed with argon or nitrogen, cool, dry and protected from light.
Package & Shipping
Package:
250kg net in new steel drum (Tare weight:22kg)
Storage:
TDI80/20 containers should be kept properly closed and stored
indoors in a well-ventilated
and fire-proof place.When opening the containers, operators should
wear go les, gloves and
rubber aprons.Containers should be handled carefully to avoid damage. In case ofleakage,
transfer it into another proper container in a well ventilated and
dry place. When opening the
cap, use an opener or wrench. Oncethe cap is loosened, pause until
the high pressure in the
container equalizes with the atmospheric pressure, then open the
cap slowly.
