Low outgassing plastics

For certain industries such as the semiconductor, aircraft or energy industry, there are strict requirements for the purity of plastics with regard to outgassing and the presence of ionic impurities. 
Low outgassing materials are used in applications in high vacuum environments such as aerospace or semiconductors. Many high performance plastics from Ensinger are able to meet these stringent requirements, offering maximum material purity, while also ensuring minimal water absorption, resulting in added stability when working at high vacuum. Part rejection rates can be reduced because of the minimal risk of contamination.

 Ionic purity

In ultra clean production environments such as in the semiconductor and solar industry, ion impurities can result in contamination and higher rejection rates.

The following Ensinger high-performance materials for semiconductor applications can be classed in the “high purity” category:

High-purity plastics

Tests in compliance with the ESA regulation (ECSS-Q-70-02) indicate no condensable impurities in TECASINT. The following products can thus be used in high vacuum applications:

TECASINT 4111 natural

It is a unfilled polyimide, which exhibits extremely high thermal stability, extremely low moisture absorption and high mechanical rigidity.

TECASINT 1011 natural

TECASINT 1011 is an unfilled natural polyimide. This material particularly stands out in the TECASINT 1000 product family for very high strength and elongation.

TECASINT 4011 natural

This unfilled polyimide material offers very low moisture absorption and high oxidative stability along with improved chemical resistance.

TECASINT 2391 black

This polyimide has been developed with 15 % MoS2 from the base polymer TECASINT 2011. It has optimum friction and wear properties in a vacuum

TECASINT 2011 natural

TECASINT 2011 natural is one of the unfilled natural grades. It has a very high modulus of elasticity, high rigidity and hardness. TECASINT 2011 natural is highly pure with low outgassing.

TECAPEEK natural

Polyetheretherketone (PEEK) - TECAPEEK natural is a high performance, high temperature, semi-crystalline thermoplastic manufactured by Ensinger...
