Parylene Varietals:  Matching Material to Purpose A common generic name for Poly-para-xylylene, parylene forms a protective plastic film when applied to substrate surfaces.  Application is achieved through a chemical vapor deposition (CVD) process in a vacuum, as a gas to targeted substrate surfaces.

Parylene C vs Parylene F

Posted by Sean Horn on Fri, Jun 3, 2016

Parylene C is the most widely used parylene type for conformal coatings.  It is classified as a poly-monochoro para-xylene, produced from dimer material, with one chlorine group per repeat unit on its main-chain phenyl ring. As a conformal coating, Type C can be deposited at room temperature via CVD.  The resulting film exhibits low chemical, moisture, […]

Parylene Conformal Coatings and UV Light

Parylene has numerous outdoor applications.  However, a major drawback of most parylene types is limited resistance to direct contact with UV radiation.  Daylight is the most common source of UV light.  Prolonged exposure to its high energy radiation can cause objects extensive surface damage and lead to eventual malfunction of electrical light-generating assemblies within.
