Introduction

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 market

Products Usage

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.

Packaging & Storage

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 of  
   leakage, transfer it into another proper  container in a well ventilated and dry place. When opening the cap, use an opener or wrench. Once
   the cap is loosened, pause until the high pressure in the container equalizes with the atmospheric pressure, then open the cap  slowly.
