Parylene coating is to provide functions of anti-rust, anti-corrosion, antiseptic, antifungal, lubrication, hydrophobicity to medical supplies.

Medical implants
 

Parylene is a chemical inert, bio-compatible and high-purity coating material that has been approved by US FDA for all types of in vivo implants.  Its bio-compatibility and bio-stability help to provide outstanding dielectric protection and resistance to moisture and corrosion.  In addition, with its low coefficient of surface friction, it can be applied to where lubrication is necessary.  In general, it helps to improve surface lubrication, bio-compatibility, and reliability of the implant.

Parylene is listed in the FDA's Biomaterials Framework primarily owing to its capability of surface modifications for implantable medical devices, such as coronary artery stents and pacemakers.  It protects medical devices and device components and acts as an acceptable contact surface for cell tissue as well.

Medical electronic devices

Parylene coating protects medical electronic components against moisture, bio-liquids, and bio-gas which may cause premature failure of these components during service.  It not only helps to extend service life of components, but also reduces cost of repairment and out-of-order risk at critical times. Parylene coating complies with the EU Hazardous Substances Prohibition Directive (RoHS) 2002/95/EC.

Forming eguipment for medical supplies
 

The lubricating nature of Parylene coated surface makes it an ideal de-molding agent for forming equipment, such as wire spindles.  Parylene-coated molds eliminate peeling and lamination of the formed components and extends the service life of component indirectly.  In general, it leaves no residuals on the surface of molded products.
