    As medical devices become smaller and more compact, theuse of Parylene coatings finds increasing value due to its molecular leveldeposition. Thin film, pinhole-free Parylene conformal coatings provide theultimate protection for life-saving devices and instruments in the medicalindustry. Inert, vacuum deposited Parylene is biocompatible and biostable andoffers excellent dry-film lubricity, thermal stability, moisture, chemical anddielectric barrier protection. Additionally, Parylene is FDA-approved (with aUSP XXII, Class VI biocompatibility rating) and is safe for use within thebody.

    PCT Parylene is USP Class VI Approved

    Parylene is a thin, vacuum-deposited polymer. It differsfrom conventional coatings in that it is deposited on objects at roomtemperature as a film, and does not use solvents, catalysts, plasticizers, orother feature-enhancing additives. It is based on a high-purity raw materialcalled di-paraxylylene, which is a white, crystalline powder. A vacuum andthermal process converts the powder to a polymer film, which is formed onsubstrates at room temperature.

    Parylene Medical Coating Services
    Parylene coatings protect a wide array of medical devices and componentsincluding stents, catheters, pacemakers, electrosurgical tools, epiduralprobes, mandrels, needles, and more. Medical devices used in surgicalprocedures are selectively coated with Parylene to improve their lubricity andto provide selective electrical insulation. The coating also protects and lubricateshypodermic needles and can create a biocompatible barrier on implantabledevices and prosthetic hardware. Parylene’s unique properties include preciseconformance to substrate topography, pinhole-free coverage in very thin layers,and the ability to penetrate and coat complex surfaces. Parylene film resistschemical attack from organic solvents, inorganic reagents, and acids; itadheres well to many surfaces, and offers exceptional dielectric strength.Parylene has a lubricious surface, with a coefficient of friction whichapproaches that of PTFE (Teflon).

    Parylene is the ideal choice for most types of substratesincluding glass, ceramics, plastics, metals, elastomers and silicone rubber.Parylene’s optically clear coatings have the ability to conform to any shapesuch as sharp edges and points. Parylene does not promote the growth ofbiologics. Its surface is unsuitable for the proliferation of bacteria andother pathogens.
