Many people have never heard of parylene before, but when you work in an industry that deals with minuscule technological items that need protection you are surrounded by it. Here are three things to know about parylene.
1. The Man Behind the Science
Michael Szwarc, a student of physical chemistry, started to develop parylene in 1947. He began by studying the individual strength of chemical bonds and their reaction to high temperatures followed by the decomposition rates. Once he started to notice the unmoving physical and chemical durability of parylene, he wanted to utilize it. By 1965, parylene was commercialized to use as a conformal coating.
2. Typical Applications
Electronics large and small benefit from parylene and several industries rely on it to protect their projects. From scientific to medical, parylene is present is many day to day items. Space exploration has parylene present in its electronics as parylene has a high resistance to harsh environmental impacts. You can also find it in your home in items like the microwave and even your cell phone.
3. Features of Parylene Coating
Manufacturers choose parylene as a conformal coating for many reasons. It is not the easiest or most convenient coating, but it provides extended benefits that outweigh the cons. First, it has no curing cycle. Once it is applied to the surface, it is ready to go. Second, because it is implemented as a vapor, the covering is much more uniform. With other coatings, you run the risk of leaving a gap in the coating and exposing the component to environmental threats. Lastly, it can be used for human implantable devices because of its chemical strength.
Parylene is all around us in medical devices and commonly used home technology.
