TDI 80/20 Polyol Toluene Diisocyanate

TDI 80/20: Mainly refers to a mixture of 80% by mass of 2,4-toluene diisocyanate and 20% by mass of 2,6-toluene diisocyanate. Sometimes also refers to toluene diisocyanate, aliases: toluene diisocyanate, toluene, and methyl phenylene diisocyanate. Nitration of toluene produces dinitrotoluene, and then reduces toluene diamine. Toluene diamine reacts with phosgene to obtain TDI. Colorless liquid. There is a pungent smell. The color becomes darker in daylight. Sodium hydroxide or tertiary amine can cause polymerization. Reacts with water to produce carbon dioxide. It is miscible with ethanol (decomposition), ether, acetone, carbon tetrachloride, benzene, chlorobenzene, kerosene, olive oil and diethylene glycol methyl ether. poisonous. May cause cancer. It is irritating.

Characteristics of TDI 80/20:

1. Toluene Diisocyanate TDI 80/20 is belongs to isocyanate products, which is widely used in producing polyurethane elastomers, top grade polyurethane coating and other industries.
2. Toluene Diisocyanate TDI 80/20 is isocyanate ester product, can replaced all or part of the t80, can improved the compression load of the product , Diisocyanate TDI 80/20 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. Toluene Diisocyanate TDI 80/20 is an aromatic isocyanate, a precursor to Polyurethanes (PU) that mostly used for making flexible foams. Diisocyanate TDI 80/20 is produced for reaction with polyols to form polyurethanes.

TDI 80/20 STORAGE:

TDI 80/20 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.

TDI 80/20 FIRST AID:

In the event of inhalation, remove the patient from the contaminated area. In more serious cases, administer therapeutical oxygen, and send for a doctor. In the event of contact with the skin, immediately remove the soiled garments. Immediately wash the affected area thoroughly with soap and water. Send for a doctor. In the event of contact with the eye, wash immediately with generous amounts of water for at least 15 minutes keeping the eyes well open.Send for a doctor. In the event of ingestion, immediately drink a large amount of water. Send for a doctor.
