Parylene N consists of a linear carbon-hydrogen molecule structure. It’s the most fundamental, basic form of Parylene, which makes it suitable for devices that see high-frequency use. This type is distinguished by its vacuum stability and low dielectric constant. When going through the deposition process, Parylene N — along with Parylene C — has a higher deposition rate than many other types. This quality makes it convenient for commercial use, although it’s not quite as widespread as Parylene C.

Parylene N is also halogen-free. Halogens include elements like fluorine, bromine, and chlorine. This quality generally makes Parylene N preferable to Parylene C, as some industries require the Parylene coatings they employ to be halogen-free. For example, halogens in electronics can bio-accumulate within living beings, and they can be toxic to the environment when burned.
The most common applications for this Parylene coating include the following:
• Printed circuit boards: Most Parylene types protect the delicate inner workings of complex circuitry.
• Elastomers: Manufacturers use Parylene N to coat elastomers, polymers with weak molecular forces.
• Electronics: Most types of this material are excellent for protecting electronic devices, whether medical or non-medical.
Application:
• Medical Devices
• Aerospace & Defense
• Electronics
• LEDs
• Automotive
