- Fluoropolymer sheets provided by Alfa Chemistry Fluoropolymers are available in various sizes and thicknesses. PTFE sheets of standard size 1500x1500 mm and different thicknesses are available from stock.
- If customers have other size requirements, please contact us for customization.
- The materials of our fluoropolymer sheets include PTFE, FEP, PVDF, etc.
- If you need to avoid static charges, anti-static fluoropolymer sheets are the recommended choice.
- If you need to bond fluoropolymer plates, etched fluoropolymer plates are the recommended choice.
Properties
PTFE
- Excellent chemical resistance
- Operating temperature -190°C to +260°C
- Maximum fatigue resistance
- Flame retardant-UL94V0
- Not sticky
- Low friction
- Anti-ultraviolet (no aging)
- No moisture absorption (water absorption rate<0.01%)
- Very good dielectric insulation performance
- The performance of PTFE can be improved by adding carbon, graphite, glass and other additives.
FEP
- Melting temperature is lower than PTFE
- More flexible than PTFE
- Transparent/transparent
- Low dielectric constant (insulation)
- Chemically inert
- Very low coefficient of friction
- Anti-stick performance
- Anti-ultraviolet (no aging)
- No moisture absorption (water absorption<0.01%)
- Working temperature from -200°C to +205°C
PVDF
- Excellent creep and fatigue resistance
- Excellent thermal stability
- Excellent radiation resistance
- Often used as an insulating and protective layer in chemical applications
- Anti-ultraviolet (no aging)
- High dielectric constant
- Working temperature is -20°C to +130 °C
Applications
- Polytetrafluoroethylene sheet can be used for electrical insulation, sealing gasket, anti-sticking material, lubricating material. The added material can be glass fiber, carbon, graphite and so on.
- The extruded ECTFE sheet can be thermoformed into various parts, such as the battery box of a pacemaker.
- The surface adhesion of the surface-modified fluoropolymer plate is improved. Therefore, the active coating of titanium dioxide can be fixed on the surface of the activated fluoropolymer substrate through the sol-gel dip coating method, which exhibits very high photocatalytic activity and bactericidal activity.
