| PVDF is strong and tough as reflected by its tensile properties and impact strength. Compared to many thermoplastics, PVDF has excellent resistance to creep and fatigue, yet in thin sections such as films, PVDF components are flexible and transparent. Applications Include: Filters Diaphragms Release films Piezoelectric films Chemical resistant tank linings Fuel cell seals Medical bags Advantages of PVDF Film: Excellent chemical resistance Stable to UV and the effects of weather Low NBS smoke generation and superior LOI Excellent transmittance of solar energy Excellent dielectric strength High heat resistance Excellent physical and mechanical properties for a fluoropolymer Resin FDA compliant FM 4910 approved&& |
