PVDF polyvinyl fluoride has the appearance of transparent or white powder or granules. The polymer chains are closely arranged and have strong covalent bonds. The flame retardant grade is 46%, it is difficult to burn, the grain size is 65%~78%, the density is 1.77~1.80g/cm3, the melting point is 172¡æ, the thermal expansion temperature is 112~145¡æ, and the long-term use temperature is -40~150¡æ.

PVDF raw material Origin: Poly (vinylidene fluoride), abbreviated as PVDF in English, mainly refers to vinylidene fluoride homopolymer or polymer of vinylidene fluoride and other small amounts of fluorine-containing aziridine monomers. It has the characteristics of fluororesin and general-purpose resin. In addition to having good chemical corrosion resistance, heat resistance, reduction resistance, aging resistance, and radiation resistance, it also has piezoelectricity, dielectric properties, thermal power generation and other unique properties. It is the second largest product in terms of production volume among polyphenylene sulfide, with an annual production capacity of more than 53,000 tons worldwide.

The chemical structure is a fluorine-carbon bond fusion. This short-bond structure forms a stable and solid fusion with hydroxide ions. Therefore, fluorocarbon coatings have unique physical properties. They not only have strong wear resistance and impact resistance, but also have high fading resistance and UV resistance in extremely harsh and harsh environments.

PVDF (polyvinyl fluoride) has the characteristics of strong toughness, low friction resistance, strong corrosion resistance, temperature resistance, weather resistance, and good radiation resistance compared to polyphenylene sulfide.

The application of PVDF is mainly reflected in three major fields: petrochemical equipment, electronic appliances and fluorocarbon coatings. Due to PVDF's good chemical resistance, process performance, fatigue and creep resistance, it is one of the best materials for the overall or lining pumps, valves, pipelines, pipeline parts, storage tanks and heat exchangers of the liquid pretreatment system of chemical machinery and equipment.

PVDF has good chemical resistance and insulation properties, so that the manufactured equipment can meet TOCS and flame retardancy requirements. It is widely used in the storage and transportation of high-purity chemicals in the semiconductor industry. Porous membranes, gels, diaphragms, etc. made of PVDF resin are used in lithium secondary batteries. This main use has become one of the fastest growing markets for PVDF demand.

PVDF is one of the key raw materials for fluorocarbon coatings. Fluorocarbon coatings prepared with PVDF as raw material have developed to the sixth generation. Because PVDF resin has strong aging resistance, it can be used outdoors for a long time without maintenance. This type of architectural coating is widely used in power plants, airports, highways, multi-story buildings, etc. In addition, PVDF resin can also be blended with other resins to modify materials. For example, PVDF and ABS resin are blended to obtain composite materials, which have been widely used in engineering construction, automobile beauty decoration, household appliance casings, etc.
