Performance of PVDF Tubing

PVDF:  Polyvinylidene fluoride built F-2. English name PolyVinylideneFluoride,  referred to as PVDF, molecular formula ∈ CF2-CH2 ∈ n, molecular weight  of 40 to 60 million. PVDF  is one of the fluorinated plastics developed in the 1960s. It is a  monomer with trifluoroethylene, hydrofluoric acid and zinc powder. After  polymerization, it is a white crystalline solid and belongs to  homopolymer. PVDF  molecular structure of regularity, molecular fluorine atoms and  hydrogen atoms of similar size, polymer chain arrangement closely, and  there is a strong hydrogen bonding effect, so the polymer compound  tensile strength, compression and impact of mild Toughness and so are relatively large. PVDF  low melting point (about 170 ℃), so processing performance is good,  easy molding, general thermoplastic processing methods can be used (such  as injection molding, extrusion, blow molding, oh well intentionally  shaped). PVDF  chemical stability is good, with excellent chemical resistance and good  heat stability, can be -62 ℃ ~ 150 ℃ temperature range of long-term  use. At the same time, the high dissociation constant is one of the good insulating materials. Ability to remove hydrochloric acid, strong solvents, all salt, acid, minus, diameter, halogen and other media. Anti-wear,  self-lubricating properties, although imports of raw materials,  expensive, one-time investment, but the price is much lower than the  import pipe, and its excellent corrosion resistance, unparalleled  service life, high safety factor , Reduce maintenance, will bring you a significant comprehensive economic benefits.
