LOW OUTGASSING MATERIALS

Low Outgassing (also known as off-gassing) refers to the release of gas trapped within a solid, such as high frequency circuit-board material. The effects of outgassing can impact a wide range of application areas in electronics, from satellites and space-based equipment to medical systems and equipment.  In space-based equipment, released gas can condense on such materials as camera lenses, rendering them inoperative.  Hospitals and medical facilities must eliminate materials that can suffer outgassing to maintain a sterile environment. 

In the vacuum of deep space, outgassing has contributed to the degraded performance of charge-coupled-device (CCD) sensors in space probes, prompting NASA to develop exacting procedures for evaluating materials prior to their use in space. 

ASTM E 595 is a testing method that has been used to determine if a particular component is acceptable for use in a low outgassing environment. Historically, a total mass loss (TML) of 1.00% and collected volatile condensable material (CVCM) of 0.10% have been used as screening levels for rejection of spacecraft materials.

Breyden Products Inc. Low Outgassing Polyester Tape, A-A-52081 and Low Outgassing Fiberglass Tape, A-A-52083 meets or exceeds the acceptable level of CVCM, TML and WVR. Breyden lacing tapes are tested in a NASA approved lab every 6 months.
