Parylene is a common name for a polymer whose main chain consists of p-phenylenediyl -C6H4-, connected by 1,2-ethanediyl bridges -CH2-CH2-. It can be obtained by polymerization of p-xylene -H2C=C6H4=CH2-. Parylene is mainly used for protective coatings in various industries.

Its main applications include:

1. Aerospace and defense: The aerospace and defense sectors use parylene to protect sensitive equipment and components from extreme environmental conditions and improve reliability and service life.

2. Medical devices: In the medical field, parylene coatings are applied to devices such as implants, catheters and surgical instruments to provide biocompatibility and corrosion-resistant layers that can be safely used in the human body.

3. Optics: Parylene coatings are applied to optical lenses and other components to reduce reflections and improve performance.

4. Electronics: Parylene is often used to coat electronic components and circuit boards to protect them from moisture, chemicals and other environmental factors that may cause damage or corrosion.

5. Consumer products: It is also used in various consumer products such as watches and smartphones to provide a durable protective layer.

Fangcunda has independently developed and produced Parylene products for more than 10 years. Over the years, it has been providing high-quality raw materials for global well-known brand customers. Its main products are:

Parylene AF4:

Parylene AF4 dimer has super high temperature resistance, UV resistance, radiation resistance, the highest permeability, the lowest friction coefficient and dielectric constant, can be used at 350℃ for a long time, and the temperature can reach 450℃ in a short term (24 hours). It is an excellent material for the protection of various components in aerospace and various extreme weather conditions.

Parylene C:

Parylene C powder combines good electrical and physical properties, and its coating has ultra-low water molecules and corrosive gas transmittance.

Parylene F:

Parylene F powder inherits the UV resistance and high and low temperature resistance of AF4 powder, and the long-term use temperature reaches 200℃.

Parylene DM:

Parylene DM is a unique new member of the Parylene series, combining excellent barrier properties, electrical insulation properties and mechanical properties. It can provide excellent moisture protection and resist corrosive solvents and gases, and can meet the needs of industries with particularly high environmental requirements.

Parylene N:

N powder is halogen-free, has good dry lubrication effect and anti-adsorption ability, and has super strong penetration ability and dielectric strength.

UVF (Parylene Fluorescent Powder):

Parylene coatings are difficult to identify due to their good optical transparency. However, Parylene UVF coatings can emit fluorescence under specific light sources, which can be easily and efficiently identified, and the various properties of Parylene UVF are exactly the same as those of the corresponding Parylene coatings.

Fangcunda is committed to continuous innovation, meeting customers' diverse needs for protective coatings, and providing the best solutions. If you have any questions about our products or need further information, please feel free to contact us.
