The fluorinated polymers are widely appreciated for their remarkable chemical inertness and their excellent resistance to aging.Polyvinylidene fluoride (PVDF) offers the specific advantages of ease processing in accordance with all the conventional 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 thermo-mechanical properties.
The intrinsic technical superiority is one of the reasons for the success of which PVDF has achieved on the world marker for more than 20 years. But nothing is possible without a genuine quality assurance policy which Nirmala pumps & Equipments Follows with their efforts for total quality management over their products & services
