Application: | Owing to its high polarity, wettability by organic solvents, and relatively high ionic conductivity, PVDF-HFP is widely used as a polymer matrix to prepare gel polymer electrolytes for energy storage applications. For example, it can be used to enhance the performance of flexible solid-state supercapacitors. It can be used to prepare superhydrophobic polymer nanocomposites. For example, PVDF-HFP- SiO2 composite can be used to enhance the thermochromism in regioregular poly(3-hexylthiophene), P3HT. It can also be used to prepare lead-free piezoelectric flexible polymer composites for nanogenerators. PVDF-HFP can be preferred over other polymer matrices because of its higher solubility, greater free volume, and better mechanical strength. |
Application: | Wire and cable coatings, flexible and corrosion-resistant tubing, and liners for pipes and tanks. |
Features and Benefits: | Excellent thermal stability, chemical and abrasion resistance, impervious to UV degradation, self-extinguishing and retains properties on aging. Improved flexibility at subzero temperatures, stress crack resistance and elongation to break over poly(vinylidene fluoride). |
