Ensinger, Inc. TECASINT 2391 black

TECASINT 2391 black is a polyimide-based material featuring 15% molybdenum disulfide (MoS2) as a filler, designed for applications requiring high thermal and mechanical performance. With a density of 1.53 g/cm², it exhibits excellent friction and wear properties, particularly in vacuum environments, making it suitable for aerospace and cryogenic engineering applications. The material demonstrates low outgassing in accordance with ESA regulations, ensuring minimal contamination in sensitive environments. Mechanical properties include a tensile strength of 95 MPa, flexural strength of 140 MPa, and compression strength of 230 MPa. It has a glass transition temperature of 357 °C and shows good thermal stability, with a coefficient of linear thermal expansion (CLTE) of 4.0 to 5.7 x 10^-5 K^-1 depending on the temperature range. The material is also resistant to high-energy radiation and has good chemical resistance, although it is sensitive to hydrolysis at elevated temperatures. TECASINT 2391 is targeted for use in industries such as aircraft and aerospace technology, precision engineering, and vacuum technology, making it a viable option for engineers seeking reliable performance in demanding conditions.
