PVDF (polyvinylidene fluoride) is a highly stable and pure fluoropolymer offering a unique balance of properties. This material has outstanding resistance to most mineral and organic acids, aliphatic and aromatic hydrocarbons, alcohols, halogenated solvents, and oxidizing environments. PVDF provides unique chemical resistance at elevated temperatures (300° F), particularly in the presence of chlorine, fluorine, or bromine. This material also has good weathering properties and excellent resistance to aging. It is available in a wide variety of forms, is nontoxic, and meets FDA and USDA regulations for direct food contact.
Main properties:
1. Excellent chemical corrosion resistance, high temperature discoloratio resistance and oxidation resistance properties.
2. Excellent flexibility, wear resistance, high tensile strength and good impact strength properties.
3. Excellent ultraviolet resistance and radiation resistance properties.
4. Piezoelectric properties.
Applications:
1. Mainly applications in the petrochemical, electrical and electronic, and fluorocarbon coatings fields.
2. PVDF is the best materials of pumps, valves, pipes, pipe fittings, tanks and heat exchangers in oil or fluid handling system because of its chemical corrosion resistance, workability, fatigue resistance and creep resistance properties.
3. PVDF material be widely used in high purity chemical goods' storage and transportation in semiconductor industry because of its chemical stability and electrical insulation.
4. In the application of lithium-ion batteries binder, it is the fastest-growing makert in the recent years.
5. It is one of the most important raw materials of PVDF coatings, PVDF resin has superior weatherability, long-term use and without maintenance, so PVDF coating are widely used in power stations, airports, highways, high-rise buildings and so on.
