PVDF (Polyvinylidene Fluoride) is a high-performance thermoplastic fluoropolymer known for its excellent chemical resistance, durability, and electrical properties. It is commonly used in industries such as chemical processing, aerospace, automotive, and construction.
Chemical Storage Tanks: Used in industrial storage tanks for corrosive chemicals.
Piping and Linings: Found in pipes, fittings, and linings for chemical and water treatment plants.
Coatings: Applied as a protective coating on metals, including architectural panels.
Medical Devices: Used in biomedical applications due to its biocompatibility.
Electronics: Found in wires, cables, and lithium-ion battery components.
Polyvinylidene Fluoride is widely used in chemical storage tanks due to its superior resistance to harsh chemicals, relatively low melting point, durability, and long lifespan. Compared to other thermoplastic composites such as polyvinyl chloride, it offers a far safer alternative with greater durability and mechanical strength – because of this, it is a top choice for chemical storage applications.
PVDF resits a broad range of corrosive chemicals, including acids such as, hydrochloric acid, sulfuric acid, bases, and organic acids and solvents. It is ideal for storing highly aggressive substances that would degrade other plastics, metals and chemical structures.
PVDF can maintain its structural integrity at temperatures of up to 150°C (302°F), this higher degradation temperature makes it suitable for heated chemical storage and chemical reactions. Many industrial processes require tanks that can handle some applied stresses such as elevated temperatures without warping or breaking down, and PVDF provides the necessary thermal stability for these applications with thermoplastic material.
One of the standout features of PVDF is its low gas and liquid permeability, which prevents leaks and contamination. This is especially important for storing various chemicals that pose a hazard, where any leakage could pose serious risks to both the environment, nearby electrical equipment and workplace safety.
Chemical storage tanks must be able to withstand high stress, impact, and environmental wear, and PVDF excels. It remains tough and impact-resistant even under extreme conditions, ensuring a long service life. Additionally, its molecular structure and abrasion resistance makes it ideal for industrial applications where mechanical wear is a concern.
Unlike some other plastics that degrade under UV exposure, PVDF is highly resistant to sunlight and extreme weather conditions. These mechanical properties make it a great choice for outdoor chemical storage tanks, used in industries like pharmaceuticals, petrochemicals, process technology and water treatment, where tanks are often exposed to the elements.
