PCTFE

The main properties of PCTFE include:

● Corrosion resistance: Due to its high fluorine content, PCTFE is resistant to almost all chemicals and oxidants. It can be immersed in acid, alkali or oxidizing agent for a long time without any change. It can be corroded by molten alkali metals, fluorine elements and chlorine trifluoride only at high temperatures.
● Permeability: Among all plastics, PCTFE has the lowest water vapor permeability, does not permeate any gas, and is a good barrier polymer.
● Electrical properties: In terms of electrical properties, the dielectric constant and dielectric loss factor of PCTFE are relatively small over a wide frequency range, and the electrical properties such as insulation resistance and dielectric breakdown voltage are excellent, and are almost not affected by temperature or humidity. Impact, a high-frequency insulation material that can withstand harsh conditions far better than traditional materials.
● Optical properties: PCTFE has excellent optical properties. A 3mm thick PCTFE plastic sheet is optically transparent. A 2μm thick film can transmit 95% of 1-4μm infrared light. Its ultraviolet light absorption rate is also very low.
● Weather resistance: PCTFE also has good weather resistance. It has no effect on its performance after being exposed to outdoor sunlight for one year.
● Mechanical properties: The mechanical properties of PCTFE include high tensile strength and hardness. Its excellent mechanical properties make it suitable for a variety of applications.
● High and low temperature resistance: PCTFE can maintain its properties and shape in high and low temperature environments, a characteristic that makes it suitable for many high-tech applications.

The main application areas of PCTFE include:

● Aerospace: Due to its corrosion resistance, high and low temperature resistance, electrical insulation and other properties, PCTFE is widely used in the aerospace field, such as aircraft parts, satellite components, etc.
● Nuclear industry: In the nuclear industry, PCTFE is used to manufacture and package containers for nuclear fuel and nuclear waste, as well as other nuclear-related equipment.
● Electronic and electrical: PCTFE is also widely used in the field of electronic and electrical, such as cable insulation layer, protective layer of electronic components, etc.
● Medicine: Because PCTFE has excellent chemical stability, corrosion resistance and biocompatibility, it is often used as packaging materials for pharmaceuticals.
In addition, PCTFE can also be used in other fields, such as chemical equipment, insulated cables, wireless appliances, capacitors, and heat-resistant or low-temperature-resistant accessories.
