- Parylene N is a primary dielectric, exhibiting a very low dissipation factor, high dielectric strength, and a low dielectric constant invariant with frequency.
- Parylene C has a useful combination of electrical and physical properties, plus a very low permeability to moisture and corrosive gases.
- Parylene D has properties similar to Parylene C with the added ability to withstand moderately higher temperatures.
- Parylene HT is particularly useful in more extreme high temperature applications (short-term exposures up to 450°C) and those in which UV stability is required. Parylene HT also has the lowest coefficient of friction and dielectric constant, and the highest crevice penetrating ability of the four variants.
- For over 40 years, Parylene conformal coatings have provided protection to an array of devices and substrates, which are used in a host of applications and industries.
