Solef® PVDF is a semi-crystalline, melt-processable fluoropolymer that offers excellent resistance to oxidizing chemicals and barrier properties combined with exceptional fatigue resistance and long-term hydrostatic strength. It has been used successfully in domestic water supply applications for nearly 20 years and has an equally impressive track record in the chemical, semiconductor, and oil and gas industries.
Halar® ECTFE is a partially fluorinated melt-processable polymer that fills the performance gap between PVDF and fully fluorinated polymers. Its exceptional resistance to oxidizers makes it suitable for piping applications in even the harshest chemical environments.
The lower prediction limits extrapolated to 50 years time are 25 MPa at 20°C and 10 MPa at 80°C.
The presence of fluorine monomer and the high crystallinity of Solef® PVDF make it extremely resistant to a broad range of chemicals. These attributes also give the material outstanding barrier properties against water vapor, oxygen and methane to help preserve the integrity of closed systems.
