Solef® PVDF Polyvinylidene Fluoride
Solef® PVDF is a fluorinated semi-crystalline thermoplastic which is obtained by polymerizing vinylidene fluoride. This fluorinated polymer has been manufactured and marketed for more than 30 years, using both suspension and emulsion process developed and perfected by Solvay/Syensqo Specialty Polymers.
Why Solef® 6008 PVDF?
Solef® PVDF, without any additives, has the intrinsic stability inherent to fluoropolymers, even when exposed to harsh environments. It provides the user with a unique combination of properties leading to longer equipment life. The most important properties of Solef® PVDF are listed below:
- Excellent chemical resistance to most aggressive substances and solvents
- Excellent mechanical strength and toughness
- High abrasion resistance
- High temperature capabilities: continuous use service temperature up to 150°C/302°F
- Excellent ageing resistance
- High purity
- Resistance to UV and nuclear radiations
- Excellent intrinsic fire resistance
- Low permeability to most gases and liquids
- Easily melt-processed by standard methods of extrusion and molding
- Wide range of rigid and flexible grades available
