Key Application Areas – Detailed

1. Anti‑Reflective (AR) Coatings for Deep‑UV and Visible Optics

• Radar domes, DUV lithography optics, pellicle films (photomasks), silicon wafer windows – the ultra‑low refractive index of PF160/PF235, combined with ≥95% transmission, can reduce Fresnel reflection to <1% per surface when properly designed as single‑layer or multilayer stacks.
• Compatibility with spin‑coating, dip‑coating, and spray‑coating allows easy integration into existing fabrication lines.

2. Anti‑Fouling and Release Layers for Bio‑ and Microfluidic Devices

• Gene‑sequencing chips, microfluidic channels, implantable sensors – the non‑stick surface (water contact angle ≥110°) effectively resists adsorption of proteins, cells, lipids, and organic contaminants, improving assay accuracy and device lifetime.
• In precision moulding (e.g., LED lens manufacturing), PF235’s high Tg and release properties enable clean demoulding without release agents, reducing defects.

3. Low‑k Dielectric Cladding and Insulation for High‑Frequency Electronics

• Fibre‑optic cladding, 5G/6G waveguide coatings, high‑speed interconnect insulation – the dielectric constant of 1.89–1.95 and exceptionally low loss tangent minimise signal attenuation and crosstalk at millimetre‑wave frequencies.
• The amorphous nature prevents anisotropic dielectric behaviour, ensuring consistent performance irrespective of film orientation.

4. Gas Separation Membranes

• The rigid, microporous‑like free volume of these amorphous fluoropolymers imparts high selectivity for gas pairs such as O₂/N₂, CO₂/CH₄, and perfluorinated compound recovery. PF160 and PF235 have been studied for their permeability‑selectivity trade‑off, with results published in peer‑reviewed journals (see references).

5. Optical Waveguide Cladding and Interlayer Dielectrics

• The low refractive index makes PF160/PF235 ideal cladding materials for polymer optical waveguides, where index contrast with the core (e.g., ~1.5) determines mode confinement. Their thermal stability allows soldering reflow processes.

PF160 and PF235 have been tested by SGS and comply with the requirements of EU RoHS Directive 2011/65/EU and Amendment Directive (EU) 2015/863.
