Comparison of thermosetting PI and TPI
Advantages and characteristics
thermosetting PI
thermoplastic PI
Basic characteristics
It possesses excellent electrical insulation, mechanical properties, chemical stability, aging resistance, and radiation resistance. It exhibits low dielectric loss, and these properties do not change significantly over a wide temperature range (-269°C to 400°C).
It retains the high strength, high and low temperature resistance, good dielectric properties, and radiation resistance of thermosetting polyimide (PI), while also improving processability. Continuous operating temperature exceeds 240°C.
Molding method
It does not melt or flow, or even soften, when heated to its decomposition temperature, making it difficult to mold and process, resulting in limited product forms and making it impossible to recycle or reshape.
It has good melting properties and can be formed by hot molding, extrusion or injection molding. It is suitable for products with complex structures that can be formed in one step without secondary processing.
Structural features
Three-dimensional polymers are formed through chemical cross-linking to create a rigid three-dimensional network structure that cannot be repeatedly processed and molded.
Linear polymers that can be repeatedly processed.
