Fluorilon-99W

Stable white thermoplastic with extremely high diffuse reflectance, available as reflectance standards or bulk material

Fluorilon-99W™ is a sintered PTFE material with the highest diffuse reflectance of any known material. The material is both thermally (>300°C), physically, and chemically stable to all but the most hostile environments. It has been successfully used in a number of space applications as a calibration target.

The material is primarily used as a component in reflective optical systems where the highest diffuse reflectance possible is required.

Fluorilon-99W™ is available as a reflectance standard, or as bulk blocks or cylinders.

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
  • Hydrophobic
  • Chemically inert
  • Thermally stable to 300°C
  • Durable and cleanable

Fluorilon Reflectance Standards

Fluorilon Reflectance Standards

Fluorilon standards are available as 1.25″ (32 mm) or 2″ (50.8 mm) diameter disks, with a Delrin™ holder and protective cover. Larger targets (up to 10″ square in single piece, up to 48″ square/ 1200 mm as arrays) are also available, as are custom sizes.

Fluorilon is also easily machined into almost any shape; see the bulk fluorilon section or contact us for more information.

Bulk Fluorilon

Bulk Fluorilon Blocks

Fluorilon-99W is available in bulk in sizes up to 10″ x 10" x 1". Contact us to discuss your specific application.

Fluorilon can be machined into almost any shape. Our machinists have extensive experience with the nuances of machining Fluorilon; however, we also provide a guide for machining Fluorilon if you choose to engage your own machining facility.

Applications include:
  • 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
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)
