2. Vapor barrier - Wikipedia

   en.wikipedia.org/wiki/Vapor_barrier

   A vapor barrier on the warm side of the envelope must be combined with a venting path on the cold side of the insulation. This is because no vapor barrier is perfect, and because water may get into the structure, typically from rain. In general, the better the vapor barrier and the drier the conditions, the less venting is required. [7]

3. Parts cleaning - Wikipedia

   en.wikipedia.org/wiki/Parts_cleaning

   The parts are usually covered by unwanted substances, contaminants, or soiling. The definition used is quite different. In certain cases, these coverings may be desired: e.g. one may not wish to remove a paint layer but only the material on top. In another cases, where crack proofing is necessary, one has to remove the paint layer, as it is ...

4. Vapor degreasing - Wikipedia

   en.wikipedia.org/wiki/Vapor_degreasing

   Can be used on electronic parts to remove excess oil, grease, wax and other non-water soluble particles because water is not used. Used where water-based system are impractical. Cleans and prepares part surfaces for various finishing processes like painting, welding, soldering, and bonding. [2] Issues of part oxidation and water spots are not ...

5. Polyvinylidene chloride - Wikipedia

   en.wikipedia.org/wiki/Polyvinylidene_chloride

   This coating increases the barrier properties of the film, reducing the permeability of the film to oxygen and flavours and thus extending the shelf life of the food inside the package. It can also impart a high-gloss finish, which may be aesthetically pleasing and also provides a high degree of scuff resistance if applied over print.

6. Polystyrene - Wikipedia

   en.wikipedia.org/wiki/Polystyrene

   General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to air and water vapor and has a relatively low melting point. [6] Polystyrene is one of the most widely used plastics, with the scale of its production being several million tonnes per year. [7]

7. Moisture vapor transmission rate - Wikipedia

   en.wikipedia.org/wiki/Moisture_vapor...

   Moisture vapor transmission rate (MVTR), also water vapor transmission rate (WVTR), is a measure of the passage of water vapor through a substance. It is a measure of the permeability for vapor barriers. There are many industries where moisture control is critical.
