2. Characteristics and applications

 

TDI is belongs to isocyanate products, which is widely used in producing polyurethane elastomers, top grade polyurethane coating and other industries. It is isocyanate ester product, can replaced all or part of the T80 , can improved the compression load of the product ,it is widely used in the production of polyester-based soft foam, high-bearing sponges, semi-rigid ester foam, high resilience, slow rebound , paint and other industries.

 

3. Storage / transportion

 

TDI must be stored in dry nitrogen seal, a symbol of the metal container and the container placed in a cool, ventilated place, away from heat, fire and dangerous goods. Storage temperature is not higher than 45 °C , if the packaging or crystal ice bucket of TDI, do not directly heated by fire or steam containers to place them in the warm air melt naturally.Sunlight and rain should be prevented during transportation.

 

In using TDI,prevent inhaling,vapor or skin contacting or swallowing.

 

4. Usage

 

TDI is an aromatic isocyanate, a precursor to Polyurethanes (PU) that mostly used for making flexible foams.It is produced for reaction with polyols to form polyurethanes.

 

5. Package

 

250kg/iron drum,20MT/20'FCL

 

6. Description

 

TDI is a white or pale yellow liquid, has a strong pungent smell that has accumulated in the body and latent , It has a strong stimulating effect to the skin ,eyes and respiratory .If you Breath in steaming of TDI, it cause bronchitis ,lung edema ;If the skin get in touch with TDI ,it cause dermatitis ;TDI does badly heart to eyes or even blind .the long-term exposure to TDI can cause chronic bronchitis . If you are hypersensitive , it may cause asthma , breathing difficulties and coughing .

 

TDI shall be stored in metal containers sealed by dry mitrogen in cool and ventilated places and far away from heat and fire.The storage temperature shall be lower than 45°C.
