Industrial uses

 

TDI toluene diisocyanate is one of the commonly used polyisocyanates and polyisocyanates are polyurethane PU materials and important basic raw materials TDI commonly used in polyurethane industry is a mixture of 24TDI and 26TDI isomers including three commonly used brands TDI8020 TDI100 and TDI6535 The preceding figures indicate the content of 24TDI in the composition For example 80 in TDI8020 indicates that its composition is 80 24TDI and 20 26TDI 100 in TDI100 basically represents 24TDI about 98 and 26TDI has few isomers It is mainly used for producing flexible polyurethane foam and polyurethane elastomers coatings adhesives and so on
