Shanghai Qixin New Material Technology Co., Ltd. is an enterprise dedicated to the development of new materials, process optimization, and the research and development of pharmaceutical intermediates and reagents. It is committed to researching products such as Parylene F, Parylene F (VT-4), and Cefnitrothiophene. Below, the manufacturer of Parylene F will introduce what Parylene F coating raw materials are.
Perylene F: commonly known as parylene F, it is a new protective polymer coating material developed and applied by Union Carbide Co. in the mid-1960s. It is a p-xylene polymer. According to the different molecular structures, Parylene can be divided into N, C, D, F, AF4 and other types. With its unique physical properties, electrical properties, and biocompatibility, it is widely used in medical design and manufacturing, national defense and aerospace, biomedicine, MEMS and nanotechnology, cultural relic protection, and other fields, providing excellent protection for increasingly miniaturized products.
Parylene N is a high polymer of p-xylene, which has strong permeability in various types of Parylene and can effectively form thin films on various fine or blind hole surfaces. Its dielectric constant is extremely low (2.65) and its dissipation factor is small, and it does not change much with the increase of external frequency; At the same time, it has good lubrication effect and is mainly used in the fields of rubber and optics;
Parylene C involves adding a chlorine atom to the side ring of the p-xylene chain. C-type Parylene has a very low permeability of water molecules and corrosive gases, and its deposition growth rate is much faster than that of N-type, resulting in poorer permeability compared to N-type; It is currently a widely used and well protected Parylene material;
Parylene D is a Parylene with two chlorine atoms on the side ring of the p-xylene chain, which exhibits relatively better physical and electrical properties at higher temperatures, and has better thermal stability compared to N and C types;
ParyleneF is the substitution of four H atoms on the benzene ring by F. ParyleneF has the advantages of UV resistance and high temperature resistance of ParyleneAF4. Due to the limitations of its production process, the preparation efficiency of ParyleneAF4 is very low, while ParyleneF has relatively more commercial value;
Through the above content, everyone should have a certain understanding of ParyleneF. This article is organized and published by the manufacturer of ParyleneF - Shanghai Qixin.
