White Polyimides

Thermalbright® Polyimide

Thermalbright® Polyimide is a breakthrough high temperature, highly reflective, essentially opaque, white polyimide film. Typical polyimides are orange colored and highly absorptive when filled with white pigments, but Thermalbright is bright white in color and contains no silicones, acrylics or non-polyimide polymers.

Thermalbright is highly customizable and available in two different versions, Thermalbright® C and Thermalbright® N.

 Thermalbright® C is an electrostatic dissipative (ESD) capable material and Thermalbright® N for applications that require electrical insulation.

Performance

Unlike traditional “white polyimides,” Thermalbright® Polyimide is not a white acrylic laminate on top of an orange polyimide, it is a single film of white polyimide. This novel material is useful in thermal control applications requiring good UV and VUV durability.

  • High Optical Density / Light Blocking
  • Low Solar Absorptivity (0.11) High Emissivity (>0.64 at 1 mil thickness)
  • Low-Temperature Cure
  • Sprayable and Castable
  • Glass Transition Temperature 263 °C

Thermalbright® Polyimide is commercially available in rolls up to 60″ wide, as well as in castable and sprayable liquids. Thermalbright® Polyimide is ideal for use as thermal control materials, high-temperature labels, high temperature reflective materials, and other materials requiring long-duration exposure to extreme environments while retaining high reflectivity.

CORIN® XLS – Atomic Oxygen Resistant Polyimide

CORIN® XLS Polyimide combines polyimide and nanocomposite technologies to deliver unsurpassed levels of optical clarity, oxidative stability, and stability to solar radiation. CORIN® XLS Polyimide received a prestigious R&D 100 Award in 2008, recognizing it as one of the most important inventions of the year.

CORIN® XLS Polyimide is a fluorinated polyimide nanocomposite that offers the highest atomic oxygen (AO) durability and highest light transmission of all the NeXolve colorless polyimides, making it an ideal lightweight substitute material for glass used in space PV arrays in low earth orbit (LEO).

CORIN® XLS Polyimide exhibits a glass transition temperature in excess of 250°C and can be used as a replacement for glass substrates in display applications.

CORIN® XLS Polyimide can be processed with organic solvents for spray, dip, or casting applications.

NovaClear® Polyimide

Novaclear® Polyimide is a colorless polyimide with a higher temperature stability than NeXolve’s CP1 Polyimide, exhibiting a glass transition temperature exceeding 330°C.

NovaClear® Polyimide is a transparent, colorless polyimide with temperature durability comparable to many traditional amber polyimides.

NovaClear® has a low yellowness index and high Tg which make this material suitable for use in display applications with high temperatures. It is available as a film, liquid resin, or raw polymer powder.

Liquid NovaClear® resin can be direct coated onto many substrates; however, unlike traditional polyimide resins, no high temperature cure is required for this material. NovaClear® can be custom formulated with pigments, dyes, and many other additive chemistries to meet the needs of many applications.
