Paralene, Paralyne, or Parylene: Correctly Spelling and Using This Superior Conformal Coating

Posted by Sean Horn on Fri, Dec 1, 2017

Accidentally discovered in 1947, by chemist Michael Szwarc, the polymer parylene originally bore his name, and was known for a brief period known as Szwarcite. Working to thermally decompose the solvent p-xylene at temperatures exceeding 1000 °C, Szwarc identified the monomer para-xylylene di-iodide as the only product resulting when para-xylylene was reacted with iodine.

Perhaps the most reliable of the conformal coatings, parylene (para-xylylene di-iodide) is also one of the more expensive coating options.  Production costs typically encompass three primary expense categories — raw materials, labor, and lot volume.  Of the three, labor expenses are generally the most costly, but raw materials can add significantly to production overhead; materials’ [&he

Applied in a gaseous form to component surfaces through a chemical vapor deposition (CVD) process, parylene (Poly-para-xylylene) films protect printed circuit boards (PCBs) and similar electrical assemblies.  Gaseous CVD application supports efficient coating of complex component surfaces characterized by crevices, exposed internal areas, or sharp edges.  Depending on the specific use, parylene
