Outgassing in Harwin plastics

Outgassing (sometimes called offgassing) is the release of gas that was dissolved, trapped, frozen or absorbed in any material. Outgassing can include sublimation and evaporation (phase transitions of a substance into a gas), desorption, seepage from cracks or internal volumes, and gaseous products of slow chemical reactions. All can potentially introduce contaminants into a previously clean product.

Although this does happen under normal conditions to a small extent, the effect is most notable in vacuum or near-vacuum conditions. For Harwin products, this is a possibility for all plastics used in the manufacture of our products.

Harwin has requested information from our plastic suppliers to confirm outgassing figures for these materials used on active products. The information is given in the following table or you can download the PDF version here.

If the product you are interested in is not listed, do please use our Contact Form to ask the Technical Team for specific assistance.

The NASA outgassing data was obtained using test ASTM E 595-77/84/90 “Total Mass Loss (TML) and Collected Volatile Condensable Materials (CVCM) from Outgassing in a Vacuum Environment”. Materials having a value of 1% TML or less, and 0.1% CVCM or less, are described by NASA as”Low Outgassing”. The data is listed on the dedicated Outgassing page on the NASA website.
