1. What is parylene?

Poly-p-xylene, also known as parylene, is a general term for polymer films with a polyxylylene structure prepared by chemical vapor deposition. It has extremely excellent electrical properties, resistance Thermal, weather and chemical stability. There are mainly Parylene N, Parylene C, Parylene D, and Parylene AF4. It adopts vacuum pyrolysis gas phase deposition process, and can be made into extremely thin films, mainly used as films and coatings, electrical insulation media, protective coatings and encapsulation materials for electronic components.

2. Main features of parylene coating

The parylene coating is colorless and transparent, and there is no pinhole when the film thickness is 0.1 μm. It has stable chemical properties, good biocompatibility, and good barrier to gas. Working principle:

The dimer is pyrolyzed at high temperature to generate diradicals, which are then introduced into the film-forming chamber to condense on the surface of the film-forming object and polymerize rapidly to obtain a uniform and dense parylene film.

3. Parylene coating effect

Function 1. It can improve the wear resistance of the covering, and it is also a high-quality protective coating that can prevent moisture, mildew, acid and alkali, and radiation. The excellent characteristics of parylene film coating make it have broad application prospects in many high-tech fields.

Function 2. It can protect metal or non-metallic materials from environmental corrosion and prolong the excellent characteristics of toluene film coating of products, making it widely used in many high-tech fields, helping products to extend their service life and reduce economic losses.
