Both coatings showed a decrease in device resonant frequency and an increase in collapse voltage, as. ) due to its mechanical, physical, optical and chemical properties. About. Parylene is a group of polymers that are chemically precisely referred to as para-xylylene. We’re a direct descendant of the companies that originally developed Parylene, and we leverage that expertise. Poor parylene adhesion negates many of the coating’s most-valued functional properties, including dielectric strength, and resistance to the effects of chemicals, corrosive agents, and moisture. These tests have shown that Parylene N continues to burn after a flame is removed for a short time, so products coated with Parylene N may need to rely on flame retardants in the other materials of the product. Other raw materials, such as the cleaning materials and adhesion promotion mediums, also factor into the materials costs for parylene.
