Polyvinylidene fluoride Usage
1. Coating field: Polyvinylidene fluoride resin (PVDF) coating uses PVDF fluororesin and special pigments with excellent weather resistance as the main ingredients. It has been used outdoors for more than 20 years. PVDF coatings are mainly used in office buildings, commercial buildings, airports and other buildings.
2. Injection molding field: PVDF has excellent processing properties and can be processed into films, sheets, pipes, rods, etc. through extrusion molding and other methods. It has good chemical resistance, processability, fatigue resistance and creep properties, and is often used in reactions. kettle.
3. Photovoltaic field: PVDF is an excellent photovoltaic backsheet fluorine film material. Its flame retardancy is better than traditional PVF materials. Its excellent weather resistance allows PVDF to be exposed to sunlight and air for a long time without aging, and its service life can reach 50 years. .
4. Filter membrane field: PVDF is not easy to absorb organic matter and has good anti-fouling properties. Compared with materials such as PES/PS/PVC membranes, it is oxidation resistant, resistant to frequent chemical cleaning, and has high mechanical strength. 5. Lithium battery binder: PVDF’s market penetration rate in all cathode binders is as high as 90%. PVDF can bond active materials, conductive agents and current collectors to the positive electrode, maintain the uniformity and stability of the active material during pulping, provide the required electron conduction in the electrode, and contribute to the battery’s capacity maintenance, service life, stability, etc. play a vital role.
