Porous PTFE

Thanks to a specific manufacturing process, GTS can produce porous PTFE parts. Different porosities are possible, allowing for the filtration of very aggressive vapours, gases, or liquids at high temperatures. The parts are easy to clean, even after filtering sticky media. Other applications are known in the field of optics.

Examples of applications:
high-performance filters,
- fluid separation,
- membranes / diaphragms,
- light measuring components (reflectors, spectrometers, photometers, integrating sphere (Ulbricht sphere), calibration targets),
Medical devices.

Highlights

• microporous The porosity is adjustable by mixing powders of different sizes and hardnesses.
• high permeability to gas, vapour and certain liquids: Capable of filtering very aggressive vapours, gases and liquids at high temperatures. Water and electrolytes cannot penetrate the pores.
• excellent chemical inertia inert to almost all chemical products
• good solvent resistance
• good resistance to high temperatures -70°C to +210°C
• Excellent electrical and thermal insulator: the dielectric constant and the tangent remain low regardless of frequencies
• Excellent non-stick Easy to clean
• very low coefficient of friction
• non-inflammable (oxygen saturation index of at least 95%)
• neutral for the body – suitable for food use
