Di-p-xylylene, also known as parylene, is a polymer material that is formed through the chemical vapor deposition (CVD) of di-p-xylylene monomers. This unique polymer possesses high thermal stability, excellent barrier properties, and biocompatibility, making it suitable for a wide range of applications in various industries. Di-p-xylylene is a linear, highly crystalline polymer with exceptional resistance to solvents, moisture, and chemicals, as well as low permeability to gases and liquids.
