Parylene coating not only has good electrical and protective properties, but also has good biocompatibility. It has passed the U.S. FDA demonstration and meets the U.S. Pharmacopoeia Biomedical Material Class VI standards. It is listed as a type that can be implanted in the body for a long time. Of biomedical materials.
With its good corrosion resistance, organic solvent resistance, antibacterial and antioxidant properties, low retardation, low coefficient of friction and biocompatibility, Parylene vacuum coating will gradually be applied to the surface coating of biomedical equipment used in international clinical practice. Instead of TiNi (Nitinol) alloy coating, it is listed as the preferred material.
Such as bone nails, probes, needles, temporary surgical instruments, urinary catheters, brakes and cochlear implants, cardiac pacemakers, brain electrodes, implantable sensors, radio frequency treatment equipment, blood analysis sensors and high-frequency scalpels, etc. Parylene coating has been widely used for micro-electronic medical devices.
