Parylene Barrier Properties
Properties of Parylene
The physical properties of Parylene and the deposition method allows Parylene to form a pin-hole free film on the subject substrate. Therefore, it provides an exceptional barrier to both liquids and gases. The table below lists the gas permeability characteristics of Parylene N and C and also shows its typical values.
