Parylene Properties

Take advantage of the unique properties of parylene, and make it part of your development toolkit. Parylene is deposited molecule by molecule onto the substrate surface during a vapor deposition process, and its crevice protection is unmatched by liquid or spray coatings.

Parylene’s outstanding electrical insulation characteristics, as well as its excellent barrier protection, make it an enabling solution for precision applications demanding the highest levels of protection. Parylene creates an unmatched barrier layer and is truly conformal, implantable, biostable, and biocompatible.

Parylene is a truly conformal coating that is typically deposited between 1-50 microns, it is pinhole free and it has excellent moisture, chemical, and dielectric barrier properties.

The unique properties of parylene, combined with the way it is deposited, enable solutions that are otherwise not possible.

The electrical, mechanical, thermal and barrier properties of parylene listed below are impressive:
