TECASINT 4011 natural
unfilled polyimide
Compared with the other TECASINT materials, the TECASINT 4000 series exhibits very low moisture absorption and high oxidative stability along with improved chemical resistance. Despite its high strength, TECASINT 4011 natural has high elongation at break and toughness. Rigidity and modulus are significantly increased in relation to conventional polyimides in a temperature range up to 260 °C. It also provides high thermal and electrical insulation. In addition, this polyimide plastic offers high purity and displays low outgassing in accordance with ESA regulation ECSS-Q-70-20.
TECASINT 4011 natural is included in Ensinger's semiconductor grade portfolio, that is produced with stringent contamination controls, and offering copy-exact compliance. As a result, Ensinger ensures the highest level of cleanliness and quality performance consistency of this unique property profile. TECASINT 4011 natural is often used in IC test sockets and electronic fixtures due to its excellent dimensional stability and micro machinability of tight tolerances.
The unique balance of stiffness and ductility allows for very low levels of burr formation, deformation, and cracking during machining of microstructures, enabling one to considerably reduce fabrication costs compared to industry standard test socket materials. This polyimide material is also often used in semiconductor manufacturing equipment parts such as in plasma etching vacuum chambers due to its very low level of outgassing and high temperature resistance.
As with all Ensinger semiconductor grade materials, we can confirm that TECASINT 4011 natural meets the limitations imposed by RoHS Directive 2011/65/EU Restriction of Hazardous Substances in electrical equipment, and can also provide further conformity declarations on request.
