Various types of seals may encounter various environments in use. In order to better adapt to various harsh environments, prevent silicone rubber from aging, and extend the life of the sealing ring, it is necessary to seal and block the seals, It must also have corrosion resistance and friction resistance.
After Parylene coating, a thin and uniform film is formed on the surface of the sealing ring. The film has superior barrier properties, optical properties, thermal properties and good anti-friction ability, which can meet the use in harsh environments and greatly Increased service life. In addition, since the film layer is very thin (2-3um), the original flexibility and outline dimensions of the product will not be affected after coating, which is an ideal way for sealing ring coating to protect.
