TECASINT 1011 is an unfilled polyimide natural grade. This material particularly stands out in the TECASINT 1000 product family for very high strength and elongation. It is characterised by properties such as a very high modulus of elasticity, high rigidity, high degree of hardness and low thermal and electrical conductivity. These are accompanied by high purity and low outgassing in accordance with ESA regulation ECSS-Q-70-20. Its previous name was SINTIMID Pur HT.
