Parylene Disadvantages

Posted by Sean Horn on Wed, Oct 17, 2012 @ 09:51 AM

Parylene offers the best protection against solvents of any conformal coating.  It is also brings to the table excellent moisture and gas protection, very high dielectric strength, and is bio-compatible.  Even with all of these benefits, there are still some disadvantages to using parylene versus other conformal coatings.

How much does parylene cost?

Posted by Sean Horn on Wed, Aug 29, 2012 @ 03:15 PM

Everyone loves the barrier properties of parylene.  The resistance to solvents and moisture, incredible dielectric strength, and the completely uniform coverage are enough to make any engineer squeal with delight.  The question that immediately follows is, “How much does parylene cost?” 

There are a couple different factors that go into decided parylene cost.  One of these factors is the material cost.  Parylene dimer can be anywhere from $100 to $10,000+ per pound depending on the type and quality.  Other raw materials, such as the cleaning materials and adhesion promotion mediums, also factor into the materials costs for parylene.

Parylene-Enabled Flexible Prosthetic Devices: A Review

Posted by Sean Horn on Fri, May 25, 2012 @ 06:10 AM

The focus of this paper was the flexible electrode and flexible coil components in which parylene C is used not simply as a coating, but as the structural material as well.  Parylene C was chosen as the structural material because parylene is pinhole-free, uniformly conforming, its low water permeability, its USP Class VI biocompatibility, and its high flexibility and mechanical strength.

Typical Conformal Coatings Used

Posted by Sean Horn on Thu, May 10, 2012 @ 08:59 AM

Different conformal coatings have a wide range of uses throughout many different industries.  While originally founded for the electronics industry, because of the benefits of using conformal coatings, it has branched into many other fields most notably medical, automotive, and LED.

 Medical Conformal Coatings Used

 While all conformal coating types can be used for different applications, for many medical devices, parylene is the way to go.  Because parylene is biologically inert, FDA approval of parylene coated devices is well-documented. The coatings comply with USP Class VI plastics requirements and are MIL-I-46058C / IPC-CC-830B listed.  Another benefit for medical devices such as stents and catheters is that parylene is entirely conformal, meaning that component configurations with sharp edges, points, flat surfaces, crevices or exposed internal surfaces are coated uniformly without voids or pinholes.
