For example, materials that release high levels of airborne molecular contaminants AMCs can degrade the performance of sensors and circuit boards in satellites. The fill material for SSP also costs less than silver-aluminum, silver-copper, or silver-glass.
Our deliverable is certainty – high quality data, test reports and certificates that you can absolutely rely on when making decisions about your materials and satm. Outgassing in high-vacuum environments can disrupt electronic equipment and optical devices.
For engineers who need low outgassing compounds with the right balance of properties, post-conditioned SSP is an excellent choice. Element can provide you with critically important data on your product or part’s performance in response to typical or extreme environmental stresses and conditions. Two parameters are measured: These include polymer potting compounds, foams, elastomers, films, tapes, insulations, shrink tubings, adhesives, coatings, fabrics, tie cords, and lubricants.
Engage with an expert today. Engaged in testing virtually every material, component and system on commercial aircraft, Element’s deliverable is satm critical, certainty. Make an inquiry today. Therefore, subsequent functional, developmental, and qualification tests should be used, as necessary, to ensure that the material’s performance is satisfactory.
Through optional post-conditioning, SSP can supply this nickel-graphite EMI elastomer in a low-outgassing grade upon request. In medical environments such as hospitals, AMCs can contaminate sterile surfaces. Most frequently associated with volatile materialsoutgassing occurs when gases and vapors are released from polymers and elastomers at above-ambient temperatures.
Dark gray in color, SSP comes in continuous rolls and can be supplied in thicknesses from 0. The user may designate additional tests to qualify materials for a specific application.

Silicones That Work
With the ability to cause damage and failure to mission-critical components, outgassing is an important characteristic to be considered in material selection.
Because outer space is a vacuum, engineers must also account for how released gases can condense on camera lenses.
ASTM E defines testing procedures for evaluating changes in material mass caused by outgassing in high-vacuum environments.
The overall mass loss can be classified into noncondensables and condensables. Each specimen must be weighed within 2 min after opening the vial to minimize the loss or absorption of water vapor while exposed to an uncontrolled humidity environment.
Historically, TML of 1. In addition to measuring outgassing levels, our experts can provide testing and data about residual gas analysisthermal properties and other aerospace properties. Terms and Conditions of Sale Contact. To obtain these values, multiple samples of this post-conditioned, nickel-graphite filled silicone were tested. After a hour outgas exposure, the specimens and the condensing plates are weighed to determine mass loss, and the percentage of the volatile effluents that were collected during testing.
The astk must be capped before removal from the conditioning chamber. Samples tested at other temperatures may be compared only with other materials which were tested at that same temperature.

Condensation from this process can collect on sensors, electronics and navigational equipment, causing damage to mission-critical equipment. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
