Product Description
Parylene D, the third member of the series, is produced from the same dimer as Parylene N modified by the substitution of the chlorine atom for two of the aromatic hydrogens. Parylene D is similar in properties to Parylene C with the added ability to withstand higher use temperatures (up to 125°C).
