PVDF (polyvinylidene fluoride) sheets and rods are plastic materials with special properties that are widely used in a number of applications. Below are some of the key features and application areas:
Chemical stability: PVDF has excellent resistance to acids, alkalis and chemicals, making it ideal for use in chemical equipment.
High thermal stability: capable of being used at higher temperatures, making it suitable for equipment that needs to withstand high-temperature environments.
Good mechanical properties: high strength and hardness, ensuring that it is not easily deformed or damaged during use.
Weather resistance: resistant to UV radiation, not easy to aging, suitable for outdoor equipment.
Application areas:
Chemical industry: used in the manufacture of corrosion-resistant equipment, such as storage tanks, pipelines, etc.
Electronic industry: used in some electronic components, such as circuit boards, electronic packaging materials.
Environmental protection field: equipment manufacturing for waste water treatment, such as sewage treatment systems.
Considerations for selection:
Material purity and quality: to ensure that the performance of PVDF sheets and rods is stable.
Mechanical properties: Select the appropriate mechanical performance parameters according to the actual needs.
Chemical resistance: Select products with appropriate chemical resistance according to the usage environment.
Price and cost: comprehensively consider the cost-effective, choose the most suitable PVDF sheets and rods.
PVDF (polyvinylidene fluoride) sheets and rods are plastic materials with special properties that are widely used in a number of fields. Below are some of the key features and areas of application:
PVDF, homopolymer of 1,1-difluoroethylene or copolymer of a small amount of modified monomer and VDF, semi-transparent or white powder or granule, with excellent properties such as solubility, crystallinity and thermal stability.
The main application areas are:
Photovoltaic backsheet: The fluorine-containing backsheet films used in the photovoltaic field mainly include PVF and PVDF films. Compared with PVF membrane, PVDF membrane has more excellent properties such as UV resistance, chemical resistance, flame retardancy, wind and sand resistance, recyclability, and densification, which can better protect the photovoltaic cells.
Lithium battery: PVDF has excellent corrosion resistance and chemical stability, and it is mainly used as positive binder in potassium batteries, and there is no suitable alternative at present. In addition, PVDF can also be used to manufacture potassium battery diaphragm and diaphragm coating.
Paint: PVDF made of paint resistant to oxidation and optical degradation, does not fade, can withstand air, water, mold, acid and alkali, salt spray, etc., the service life of more than 30 years, without maintenance, has a very high cost-effective, is the building of the external wall of the roof and a variety of building materials, the ideal decorative materials.
Water treatment: PVDF hollow fiber membrane has excellent chemical properties with good pollution resistance, oxidation resistance and has good tensile strength and high water throughput, can be used in industrial wastewater, domestic wastewater treatment, seawater purification and other water treatment fields.
Chemical industry: PVDF chemical resistance, excellent processability, fatigue and creep resistance, chlorine, Australia halogen and halogen compounds have excellent resistance characteristics, so PVDF is the petrochemical and other industrial equipment, fluid handling system as a whole or lining pumps, valves, piping, piping fittings, tanks and heat exchangers, one of the best material
Semiconductor: Semiconductor manufacturing has very high material requirements for related equipment, mainly including roughness, chemical stability, electrical insulation, etc. PVDF has low surface energy, good corrosion resistance, good electrical insulation performance, and can be used for storage and transportation of high-purity chemicals, filter housings and other components.
Medical Devices: PVDF is safe and harmless, and can be used in the field of medicine.PVDF can be made into a variety of porous and non-porous materials, and can also be made into biological materials. For example, PVDF can be made into artificial blood vessels, Archimedes spiral water purifiers, and pharmaceutical packaging materials to replenish gas cancer tablets.
Wire and cable: PVDF has insulation, corrosion resistance, self-extinguishing, low density, waterproof, aging resistance and easy to process, can be used for the manufacture of special wires and cables, connectors, sheaths, cathodic protection jacket, etc., for corrosion-resistant requirements of the place, high-rise buildings, military and aerospace devices.
