High-performance semi-crystalline fluoropolymers

Solef® 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.

Processing

Solef® 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 Solef® PVDF can be easily assembled using standard welding methods, such as:

  • Hot air welding with welding rod
  • Butt welding
  • Heat-sealing
  • Ultrasonic
  • IR welding
