TECASINT 2391 has been developed with 15 % MoS2 from the base polymer TECASINT 2011. It has optimum friction and wear properties in a vacuum, which means it can be used in space travel applications, in a vacuum or in inert gases (techn. dry). The plastic displays low outgassing in accordance with ESA regulation ECSS-Q-70-02.
