Tubing and Parylene Coating

Posted by Sean Horn on Fri, Jun 15, 2018 @ 07:30 AM

Operationally, a tube is a hollow cylinder composed of glass, metal, plastic or a similar substance, designed to contain or transport something, typically liquids or gases.  When many people think of tubing, they envision its use in construction or mechanics.  Tubing of this nature is defined not only by its purpose and the stuff its made of, but also by two dimensions -- outside diameter (OD) and wall thickness (WT).

Parylene Protects Stents

Posted by Sean Horn on Fri, Dec 16, 2016 @ 07:48 AM

Biocompatible parylene conformal coatings provide superior protection for medical stents.  They represent an enabling technology consistently applied to medical devices of all types for 35 years, to diminish problems stemming from surface microporosity and consequent biofluid corrosion after implant.  Providing a reliable barrier to chemicals and moisture, parylene’s static and dynamic coefficients of friction are comparable to those of Teflon.

Best Implantable Device Coating

Posted by Sean Horn on Fri, May 01, 2015 @ 08:41 AM

Implantable devices place a special set of requirements and challenges on their coatings. The moisture and broad mixture of chemicals that are found inside of the body are challenging in and of themselves. However, the body also has needs from the coatings that are placed within it. They need to be non-irritating and inert enough to be harmless. For most applications, the best choice is USP Class VI compliant parylene coatings.

Parylene for use in Bio-Medical implantable devices

Posted by Sean Horn on Tue, Jun 12, 2012 @ 10:52 AM

Whenever implantable devices come into contact with the human body, long term protection against body fluids, enzymes, proteins, and lipids is vital.  Bio-medical surfaces typically require coating to protect from moisture, chemicals, and other potentially harmful substances.

 A downfall for wet chemistry, liquid coatings such as silicones, acrylics, epoxy, or urethanes is that they do not meet bio-compatibility requirements and cannot be applied with precise control.  On the contrary, parylene does not out-gas and is very effective against the passage of contaminants from both the body to substrate or substrate to body.
