Polyvinylidene Fluoride
Features
PVDF(Polyvinylidene fluoride) is a crystalline polymer,the low melting point,approximately in the -40---150℃;high mechanical strength,with wear-resistant,cut resistant,high temperature resistance,corrosion resistance,good electrical properties(characterized byhigh dielectric constant). Also has excellent weather resistance,UV resistance,anti-radiation properties and process ability;the same time,low processing temperature,the melt flow can be made into pipe,plate,rod,film and fiber.Soluble in some organic solvents.
Density 1.75~1.78g/cm3 (Mpa)>40,the glass transition temperature of -39℃,the brittle temperature of -62℃,170℃ melting point,thermal decomposition temperature of about 350℃,the long-term use temperature of -40~150℃. Molding available thermoplastic processing methods.
Applications
The ideal chemical equipment,anti-corrosion materials,especially suitable for the occasion of theacid,organic solvents,halogens and their mixtures to use.
Widely used in electronics,electrical industry,such as electronic computerwires,Phi double-casing of aviation wires and geophysical cable.
The outer coating for optical fiber,high dielectric constant capacitors film and band,etc.
