Parylene is a generic name for poly-para-xylylene polymers used as conformal coatings in protective applications. 1a) followed up by a sputter coating of 200 nm thick aluminium (Al) (Fig. Parylene N is the basic member of the Parylene polymer series and Parylene C was the second commercially available member. It is anticipated that the chief health hazard associated. The upper faces of the piezoelectric disc were first carefully cleaned and pre-treated with Silane. Table 1:. Parylene C, the second commercially available member of the Parylene series, is produced from the same raw material (dimer) as Parylene N, modified only by the substitution of a chlorine atom for one of the aromatic hydrogens. As an example, steel panels coated with parylene C that were chilled in liquid nitrogen to -160°C withstood impacts of more than 100 in/lb. The CVD process for grow-ing Parylene C films involved the following steps: (a) vaporization of a dimer (di-para-xylylene) by the heating element of a Parylene C coating system (LH300, La Chi Enter-prise, New Taipei City, Taiwan) at 150°C and 133. 95 @ 1MHz Dissipation Factor Parylene N: 0. 0002" per hourParylene C is recommended where excellent barrier protection is needed.
