ABOUT PVDF, High-performance semi-crystalline fluoropolymers
PVDF is a fluorinated semi-crystalline thermoplastic
which is obtained by polymerizing vinylidene fluoride.
Without any additives, it has the intrinsic stability inherent
to fluoropolymers even when exposed to harsh environments,
providing the user with a unique combination of properties
resulting in longer equipment life.
In addition to the PVDF homopolymers, which are recognized worldwide
for their excellent performance in a variety of applications,
Solvay Specialty Polymers has developed a wide range of
VF2-HFP copolymers, and VF2-CTFE copolymers
to respond to specific needs of the market.
Performance
Relative Performance of Melt-Processable Fluoropolymers
In addition to Solvay PVDF resins, Solvay Specialty Polymers
offers a wide range of fluoropolymers which are also easily processable
by injection, extrusion and all conventional processing techniques.
Processing
Solvay PVDF grades can be processed using techniques
applicable to standard thermoplastics:
- Extrusion
- Injection, compression and transfer molding
- Machining
Items produced from all non-reinforced grades of Solvay PVDF
can be easily assembled using standard welding methods, such as:
- Hot air welding with welding rod
- Butt welding
- Heat-sealing
- Ultrasonic
- IR welding
DETAILS
Solvay has inaugurated
its Solef® polyvinylidene fluoride (PVDF) plant
in China, to meet booming global demand for
this thermoplastic polymer in
energy-efficient, environmental and industrial applications.
Solef® PVDF production in Changshu started in July.
Augusto Di Donfrancesco,
President of Solvay Specialty Polymers Global Business Unit.
“Solvay’s consistent expansion on the Changshu site,
this time with a new Solef® PVDF plant, shows we are committed
to serve our customers from Asia, where demand is particularly strong.
Our Solef® PVDF production presence now spans the globe with plants
in three key continents:
Europe, the United States and Asia”
Solef® PVDF is used for applications such as
* lithium-ion batteries (li-ion) in hybrid and electric vehicles (xEV),
* for offshore oil and gas pipes and liners and
* in membranes for water purification.
