Product Parameters

Physical and chemical properties

PVDF is mainly used in occasions that have extremely high requirements on purity and also need to resist solvent and acid and alkali corrosion. Compared to other fluoropolymers, such as PTFE, PVDF has a lower density (1.78 g/cm).
PVDF can be used to produce insulating sheaths for pipes, sheets, films, substrates and cables. At the same time, it can also be injection molded or welded, and is widely used in the chemical, semiconductor, pharmaceutical and defense industries. For example, it can be used to make lithium-ion batteries. In addition, it can be made into cross-linked closed-cell foam, which is increasingly used in aerospace.
Fine powder grades of PVDF, such as KYNAR 500 PVDF and HYLAR 5000 PVDF, can be used to manufacture high-end metallic coatings. This coating has very high gloss and color stability. This paint can be found in many famous buildings, such as Petronas Twin Towers, Taipei 101. This coating can also be used for metal roofing of commercial buildings and residences.
Since PVDF membranes have non-specific affinity for amino acids, they can be used to immobilize proteins in Western blot assays.
In 1969, researchers found that PVDF has a strong piezoelectric effect: the piezoelectric coefficient of the polarized (ie, put in a strong electric field to generate a net dipole moment) film is 6-7pC/N, which is higher than that of the polymer discovered at that time. The value is more than 10 times larger.
The glass transition temperature (Tg) of PVDF is about −35°C, and the crystallinity is typically 50–60%. To impart piezoelectric properties to a material, the material is usually mechanically stretched along the direction of the molecular chains and then polarized under tension. PVDF has various solid-state phases: alpha phase (TGTG'), beta phase (TTTT) and gamma phase (TTTGTTTG'). The difference between these phases is whether the molecular chain is cis (T) or trans (G). PVDF will become a ferroelectric polymer after polarization, which has good piezoelectricity and pyroelectricity. These properties allow it to be used in the production of sensors and batteries, such as PVDF films used in the sensors of some new thermal imaging cameras.

Transport/Storage Information

PVDF should be stored in a clean and dry environment at 5-30°C to avoid the mixing of impurities such as dust and moisture. Transport as non-dangerous goods, avoid heat, moisture or severe vibration during transportation.

Applications

PVDF has good chemical stability and electrical insulation properties, so that the produced equipment can meet the requirements of TOCS and flame retardant, and is widely used in the storage and transportation of high-purity chemicals in the semiconductor industry. , diaphragm, etc., applied in lithium secondary batteries.
PVDF has good chemical resistance, processability, fatigue resistance and creep resistance, and is one of the best materials for pumps, valves, pipes, pipe fittings, storage tanks and heat exchangers in the whole or lining of petrochemical equipment fluid handling systems. one.
