Development of Thermoplastic Polyurethane (TPU) Material

The enhancement of material durability is a key development theme for automakers since customers own cars longer. Research is being carried out to extend the lifetime of current thermoplastic polyurethane (TPU) materials by enhancing hydrolysis resistance while maintaining excellent low-temperature properties and scratch resistance.

This development of enhanced hydrolysis resistance without degrading the melting properties of the material was achieved by introducing a new resin structure that is resistant to the invasion of water, acid, alkalis, and other substances causing hydrolysis.
