TDI

Toluene diisocyanate (TDI) 80/20 is a specific type of TDI that is used in the production of polyurethane (PU) materials. It is a mixture of 80% 2,4-TDI (2,4-toluene diisocyanate) and 20% 2,6-TDI (2,6-toluene diisocyanate). TDI 80/20 is commonly used in the production of flexible PU foams, such as those used in furniture, bedding, and automotive applications.

TDI 80/20 is produced by reacting toluene with phosgene, a highly toxic gas. It is a clear, colorless liquid that is stable at room temperature, but it can decompose into toxic gases when heated or exposed to moisture.

One of the benefits of using TDI 80/20 is its excellent adhesion properties, which make it suitable for use in products that require strong bonding, such as shoe soles and car seats. It is also resistant to water, chemicals, and UV radiation, which makes it suitable for use in outdoor products.

TDI 80/20 is highly reactive and is used as a crosslinking agent in the production of PU foams and elastomers. It can be easily modified to suit specific applications by adding various additives, such as catalysts, flame retardants, and colorants. It is also energy-efficient to produce and has a long lifespan, which makes it a more sustainable choice in certain applications.

Overall, TDI 80/20 is an important chemical compound that is used in the production of PU materials and has a wide range of applications due to its versatility and durability. However, it is important to handle TDI 80/20 with caution, as it is a toxic compound and can decompose into harmful gases when exposed to heat or moisture.
