Fluorilon-99W™ is a stable white thermoplastic with extremely high diffuse reflectance. The material is both thermally (>300°C), physically, and chemically stable to all but the most hostile environments. The sintered PTFE product has been employed in a number of space applications as a calibration target. The primary use is as a component in reflective optical systems where the highest diffuse reflectance possible is required.

Beginning March 2005, we will begin selling bulk Fluorilon FW-99 for prototyping work on a small basis. Please call or e-mail us for available sizes, price, and delivery.

 Properties:

  • Greater than 99% reflectance in the 400-800 nm range
  • Reflectance of >97% over the 300-2200 nm range
  • Reflectance of >92% over the 200-2500 nm range
  • Easily machined into diffusely reflective components
  • Hydrophobic
  • Chemically inert
  • Thermally stable to 300°C
  • Durable and cleanable

 Physical Properties:

  • Density: 1.5-1.6g/cm3
  • Porosity: 40-50 %
  • Pore size: typically 25-35 microns
  • Decomposition point: about 400°C
  • Toxicity: GRAS (non-toxic, same toxicity as Teflon)

 Applications:

  • Flat panel backlights
  • Illuminator panels
  • Integrating spheres
  • Line and cylindrical scanners and illuminators
  • Reflective diffuser panels
  • Reflectance standards for laboratory and remote sensing applications
  • Lamp housings (xenon flash, tungsten, LEDs)
  • Collection spheres for fiber optic evaluation
  • Attenuators for fiber optics couplers

 

Fluorilon-99W is available in bulk in sizes up to 12" square and up to 2" thick. Price is dependent on size and quantity.
