Thermally Stable NIR Dyes for High-Temperature Polymer Applications

QCR Solutions supplies thermally stable near-infrared (NIR) absorbing dyes engineered to withstand the extreme temperatures of polymer processing. These materials are specifically designed for use in polycarbonate (PC), PMMA, and high-performance thermoplastics, with absorption peaks in the 700–1600 nm range.

Our dyes maintain performance under extrusion, molding, and compounding conditions—making them ideal for laser protection lenses, IR-blocking optics, secure electronics, and plastic films.

Discuss Your Application

QCR Solutions offers a broad range of Near-Infrared (NIR) absorbing dyes, spanning from narrow notch filters to wide band absorbers. Our NIR dye library includes formulations that selectively attenuate specific wavelength regions between 700 nm and 1600 nm. Dyes can be used individually or combined to create custom spectral filters tailored to your application.

These NIR dyes are compatible with coatings, inks, solutions, and plastics, and are ideal for:

Laser safety eyewear (including 1064 nm YAG)
Infrared light filters (narrow and broadband)
Welding protection lenses
Security printing inks
Graphic arts and IR-blocking films

Custom dye recommendations, technical data, sample pricing are available upon request.

Below is a representative list of our Near Infrared absorbing Dyes (500-1000nm). Also available is our helpful guide on how to calculate your absorbing dye’s starting concentration: Concentration Calculation Worksheet | 2018 | QCR Solutions Corp
