China’s thermoplastic polyimide market relies on imports and domestic development is relatively lagging behind

Thermoplastic polyimide (TPI) is a polymer with a chain structure containing imine rings and aromatic rings on the main chain. Thermoplastic polyimide (TPI) has good melting properties and can be processed by conventional plastic molding processes such as molding, extrusion, and injection. No chemical cross-linking occurs during its processing, so it can be melted during…
