Is anything given off be the material (e.g. extractables, outgassing)?
1) Silicon Gap pad and Gap Fillers, like all soft silicone materials, can extract silicone fluid (refer to Bergquist Application Note #56). Also note that Gap Pad and Gap Filler have some of the lowest extraction values for silicone-based gap filling products on the market and if your application requires no silicone, see our line of Sil-Free material. 2) Primarily for aerospace applications, outgassing data is detailed in Bergquist Application Note #117, tested per ASTM E595.
