TPU Types in Laminated Fabrics
According to the soft segment structure, TPU can be divided into polyester TPU, polyether TPU and polybutadiene TPU, which respectively contain ester, ether or butylenes; according to the isocyanine structure can be divided into yellow (MDI, TODI, NDI, PPDI, etc.) and non-yellowing (HDI, H12MDI, etc.) are classified into urethane type and urethane urea type according to the hard segment structure, which are obtained by diol extension or diamine chain extension, respectively.
