for chemical field heat resistance nano-pvdf sheetIntroduction :
PVDF is a specialty plastic material in the fluoropolymer family; it is used generally in applications requiring the highest
purity, strength, and resistance to solvents, acids, bases and heat and low smoke generation during a fire event. Compared to other fluoropolymers, it has an easier melt process because of its relatively low melting point of around 177 °C.
It has a low density (1.78) and low cost compared to the other fluoropolymers. It is available as piping products, sheet, tubing, films, plate and an insulator for premium wire. It can be injected, molded or welded and is commonly used in the chemical, semiconductor, medical and defense industries, as well as in lithium ion batteries. It is also available as a crosslinked closed cell foam, used increasingly in aviation and aerospace applications.
PVDF (polyvinylidene fluoride) is a kind of light fluoride material, with the working temperature ranging from -70 to 150 . It
features superior corrosion resistance, mechanical property, electrical insulating property, low friction coefficient,
weatherability, and radiation tolerance. Moreover, the tensile strength is two times higher than PTFE, the compressive strength six times higher than PTFE, and the abrasion resistance similar to nylon.
PVDF plates, rods are formed by the die pressing or extrusion of polyvinylidene fluoride resin. It can be widely used as the
corrosion-resistant materials, abrasion-resistant materials, corrosion-resistant equipment linings, transparent viewing mirrors, vacuum sealing materials, electrical and electronic components, and motor or instrument parts, etc.
PVDF (polyvinylidene fluoride) has the strongest toughness, low friction coefficient, corrosion resistance, aging resistance,
weather resistance and good radiation resistance in fluoroplastic.
