Polyvinylidene difluoride,PVDF, abbreviated as PVDF, is a highly non reactive thermoplastic fluorinated polymer. PVDF is mainly used in applications that require extremely high purity and resistance to solvents and acid-base corrosion. Compared to other fluorinated polymers such as polytetrafluoroethylene, PVDF has a lower density (1.78 g/cm3) and can be used in industries such as electroplating, semiconductors, and chemicals.

Due to the requirements for chemical corrosion resistance, high temperature resistance, and oxidation resistance, many tank bodies made of fluoroplastic materials are selected for material selection. PVDF material, one of the fluoroplastic materials, is one of the preferred materials for pumps, valves, pipelines, pipeline fittings, storage tanks, and heat exchangers in petrochemical equipment fluid treatment systems due to its good chemical resistance, processability, and fatigue resistance. In the electroplating industry, PVDF made tanks are widely used. Kunshan Xinruiwei’s PVDF tank welding processing adopts a new type of PVDF tank welding method, which has the characteristics of simple process, beautiful appearance, firm and reliable, no leakage, no bulging, etc. Kunshan Xinruiwei Company has become the preferred partner for many domestic electroplating and semiconductor equipment manufacturers.
