Coating for Medical
Parylene, both C and N, have seen widespread use as a coating for the medical industry. Parylene is:
- Chemically inert
- Resistant to fungal and bacterial proliferation
- USP Class VI
- FDA approved for many medical applications
These qualities make Parylene a preferred choice of coatings for the protection of many types of medical products ranging from needles, to pacemakers, hearing aids, nasal tubes, surgical hardware, more.
Parylene is an ideal barrier coating for medical products and devices.
- Parylene protects against moisture ingress on medical electronics
- Parylene is not rejected by the body’s natural immune defense (biocompatible), therefore an ideal coating for all types of implants.
- Parylene is a dry film lubricant and reduces tackiness in elastomers. It’s a preferred coating for cannulas.
- Parylene is virtually impervious to harsh chemicals. It can withstand moisture, salts, and corrosive sulphur compounds in the human ear. Parylene is frequently used in coating hearing aids and cochlear implants.
- Parylene protects parts, hardware and electronics from contamination with blood and body fluids.
- Parylene is an acceptable coating for medical products that require Gamma and E-Beam sterilization.
- Parylene can be applied in such thin layers, and with such precise conformality, that it is a preferred coating for coronary and peripheral stents.
- Parylene is a lubricious coating that is used extensively in medical guidewires and catheters (and mandrels).
- Parylene can uniformly penetrate such small crevices that it can coat the inside diameter of drug delivery devices
- Parylene is unaffected by temperatures as low as -60°C so it is utilized as a coating material in cryogenic applications.
- Parylene is optically clear and colorless so it is frequently used as a coating for lenses and certain optoelectronics.
