Application Of TDI 80/20
Toluene diisocyanate Used For Polyurethane 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.
Polyol TDI 80/20 is mainly used in polyurethane products including foams, polyurethane coatings, polyurethane rubber; polyimide fibers and adhesives are also some applications.
