Polyimide 4000 series unfilled / Tecasint 4111

Compared with the other TECASINT materials the TECASINT 4100 series exhibits extremely high thermal stability (HDT/A=470°C), extremely low moisture absorption and high mechanical rigidity. UNFILLED POLYIMIDE Compared with the other TECASINT materials the TECASINT 4100 series exhibits extremely high thermal stability, extremely low moisture absorption and high mechanical rigidity. This is accompanied by a very high oxidative stability and increased resistance to chemicals. TECASINT 4111 has a very high thermal stability (HDT/A=470°C). Rigidity and modulus are significantly increased vis-a-vis conventional polyimides in a temperature range up to 400 °C. The material has minimal thermal and electrical conductivity. The plastic is highly pure with low outgassing in accordance with ESA regulation ECSS-Q-70-20.
