Pvdf Pumps

The Fluorinated Polymer are widely appreciated for their remarkable chemical inertness and their excellent resistance to ageing.
POLYVINYLIDENE FLUORIDE (PVDF) offers the specific advantage of easy processing in accordance with all the convection methods used in the plastic industry. PVDF, polymerized, according to its own special process, offers a high degree of crystallinity to that by other processes, resulting among other things, in superior thermomechanical properties.
The intrinsic technical superiority is one of the reasons for the success which PVDF has achieved on the world market for more than 20 years.
Easy processing by : extrusion, injection, compression, rotational moulding, blow moulding etc.
Chemically inert to most acids, aliphatic and aromatic organic solvents, alcohals etc.
Very high purity.
Excellent mechanical properties over a wide range of temperatures : tensile yield strength up to 55 MPa at 23°C and 10 MPa at 150°C.
Abrasion resistance comparable to that of polyamides, and relatively low coefficient of friction.
Continuous use at temperatures as high as 150°C for the homopolymer grades (without mechanical stress).
Excellent thermal aging resistance : tensile yield strength retention over 90% after 25,000 hours at 150°C in a ventilated oven.
Unaffected by UV (>232nm) and good resistance to gamma radiation.
Excellent intrinsic fire resistance.
Very easily joined by welding and good capability for thermoforming.
Physiologically harmless and approved for contact with food products (FDA).
