No matter what you're doing, it's important to have the right tool for the job--and the same is true when it comes to parylene. However, there is often uncertainty over which type of parylene is best for a specific need. Two of the most common, and most easily confused, types of parylene are Parylene N and Parylene C, and today, they'll go head-to-head.

A Parylene Crash-Course

Before we get into the specifics of Parylene N vs. Parylene C, it's important that we take a step back and review what all parylene types have in common and what they are used for. Parylene conformal coatings are widely used in a large variety of professions, from military to aerospace to home appliances. This is because parylene offers complete coverage at very precise and very fine thickness levels, protecting a surface from environmental factors, acid damage, caustic solutions, and more--and it does all of this no matter the shape or size of the surface. Along with high levels of thermal stability and electrical insulation, parylene is the right tool for hundreds of jobs. Our parylene experts ask the questions, and parylene provides the answers and solutions.

Comparisons

So, what about Parylene N and Parylene C? Both have a lot to offer, but which is best for your needs? Here's a quick look!

  • Parylene N. Parylene N is the most basic type of parylene available. It boasts a dielectric strength that is much higher than that of Parylene C, and, on top of that, it has unique molecular motion during deposition which allows it to more closely conform to complex shapes. If you need to protect a difficult surface full of cracks, crevices, and tricky topography, then Parylene N is right for the job.
  • Parylene C. Parylene C is the most commonly used of all parylene types. Its benefits come mainly from its unique chemistry: a single chlorine atom in place of Parylene N's aromatic hydrogen atom creates an entirely different combination full of efficient electrical properties. This gives Parylene C the ability to withstand vapor permeability, making it especially protective against gasses--unlike Parylene N.
  • Decisions. Although there are many differences between Parylene N and Parylene C, it's important to remember that both types offer the same basic benefits, including thermal stability, electrical insulation, longevity, and more. Deciding which type of parylene is right for your job comes down to the specifics; consider your needs, then consider the strengths and weaknesses of each type.
