Stability in vacuum systems

Stability in vacuum systems

The parylene coating process is done in vacuum at a level of 3-10, more or less. Implementation of parylene in a vacuum in fact permits the component to be inert to the vacuum. As a product, the nature of whose method of implementation is the CVD (chemical vapor deposition) method, parylene is used in space applications without any problems of the release of gases, plasticizers, and/or other products as a result of pressure drop/vacuum rise)] For example, when leaving/taking off in the direction of space and/or during transition between atmospheres (even in simpler ballistics than satellites and/or missiles of a different kind).

The main reason for inability to resist changes of pressure and a vacuum environment is the creation of air bubbles trapped between the coating and the infrastructure. These bubbles burst during pressure changes and consequently endanger the strength of the devices during pressure changes. As set forth above, in parylene coatings having perfect conformity no air bubbles are trapped during the production process and this is why it is inert regarding the vacuum.
