Paper Thread Parylene thickness

Consumers demand smaller, faster, and more durable products in every industry. Companies are consistently being challenged with the idea of their products being faster, with additional features, and being more durable, while getting smaller.

Look at the advancements of our smartphones over the past five years. Manufacturers have been using glue, rubber seals, and gaskets to seal a smartphone. But as consumers demand thinner, faster, and now waterproof smartphones, there is less and less room for glue or other coatings that are thick. Manufacturers are looking at parylene coating to protect the vital components of their devices.

It makes sense. If parylene can protect a medical device implanted in a human body, and also protect electronics onboard a satellite, then it can protect a smartphone from the average Joe. And it's because of the way parylene is applied to components that gives it it's advanced over other coatings available in the market.

Advantages on a Molecular Level

We've talked about our parylene is applied before in our parylene deposition process. What gives parylene its unique advantage is that it is applied as a vapor, or molecular form, in a vacuum controlled chamber. In our process, we don't go off of line-of-site application, but rather a three-stage process that ends with the deposition so that the parylene is uniformly applied. There are no pinholes or uneven spots of coating that could affect the quality or performance of the product.

To illustrate how thin parylene can be applied, we take two everyday objects that are considered to be thin — sewing thread and paper.

  • Sewing thread has an average diameter of 327 micrometers, better knowns as microns, or .0129 inches.
  • Paper has an average thickness of 1016 microns or .004 inches.
  • Parylene coating can get a thin as .05 microns, or .008inches 

Parylene coating can be applied to a vast number of surfaces like plastic, metals, ceramics, and even fabrics. The only limitation would be the product must fit into the vacuum chamber for the application.

As the need for products to get smaller and faster with better functionality grows, so does the demand for the coatings that protect those products. Parylene is the clear choice for manufacturers of today's and tomorrow's military, commercial, medical, and consumer solutions.
