Product Structural Features

1. Excellent heat resistance and high dielectric strength
PVDF has a highly regular molecular structure. The fluorine and chlorine atoms in the molecule are of similar size, resulting in densely packed polymer chains and strong hydrogen bonding. Consequently, the polymer exhibits high tensile strength, compressive strength, and impact toughness. PVDF also has a melting point of around 170°C, offering excellent processability and easy molding.
2. Wear resistance, high mechanical strength, and toughness
It boasts exceptional toughness among fluoroplastics, a low coefficient of friction, and aging resistance, resulting in strong wear and impact resistance. Furthermore, it exhibits high resistance to fading and UV rays in harsh and hostile environments.
3. Weather resistance, UV resistance, and nuclear radiation resistance
It boasts high purity, excellent chemical stability, corrosion resistance, high temperature resistance, high barrier properties, oxidation resistance, weather resistance, and radiation resistance, as well as special properties such as piezoelectricity, dielectricity, and thermoelectricity.
4. Wide range of applications
PVDF piping systems are widely used in the storage and transportation of high-purity chemicals in the petrochemical, electrical and electronic industries, fluorocarbon coatings, nuclear power projects, the semiconductor industry, and the petrochemical industry.
