Molecular formula: [CH2--CF2]nProperties:
PVdF namely Polyvinylidene fluoride is a kind of crystal polymer with low melting point
(160 ~ 170), high mechanical properties, good resistance to wear , to high temperature, to
corrosion, to weather and as well with good electric insulation, high dielectric
constant. Also it is anti-ultraviolet ray, anti-radiation and easily machined. With low
processing temperature and good melting flow, it could be processed easily to make pipe,
plate, rod, film and fiber. Its heat conductivity is poor.
Usage:
Used as good anti-corrosion material in chemical industry, especially in the circumstances
of acid, organic solvents, halogens, as well as their mixture. Widely used as insulation
material in electronic / electric industries, computer industry, air/space industry to
make cable sheathing, coating layer, and condenser film, etc.
