TECASINT 2011 natural

unfilled polyimide

TECASINT 2011 is one of the unfilled natural grades. It has a very high modulus of elasticity, high rigidity and hardness. Compared with TECASINT 1011 it has significantly reduced moisture absorption, higher toughness and better machining properties. Within the TECASINT 2000 series the material has the maximum strength and elongation, together with a high modulus of elasticity and minimal thermal and electrical conductivity. TECASINT 2011 is highly pure with low outgassing in accordance with ESA regulation ECSS-Q-70-20.
