Pearly Series Polycarbonate master-batch – Controls heat producing Far Infrared Radiation (FIR) and Visible Light Transmission (VIS) wavelengths.
Unwanted solar radiation wavelengths are filtered out, allowing cool, diffused Green light and Near Infrared (NIR) to pass through.
VULCAN Solid EMBOSSED Polycarbonate sheet has all the properties of standard Solid Flat sheets but with additional light diffusing features.
The embossed texture targets users requiring softened, indirect light exposure and is most often used as interior wall claddings, windows, or skylights.
VULCAN Polycarbonate Solid EMBOSSED sheets come in sheets and rolls, and is customizable.
VULCAN Pearly has been designed as a solar heat protection application that attenuates longer wavelength heat-producing infrared radiation very effectively through reflection, but at the same time, allowing a high percentage of cool, diffused GREEN light to pass through.
Pearly have particle sizes in the range of 10~60μm, and is suitable for general-purpose infrared blocking applications.
Pearly reflects rather than absorbs heat producing far-red solar radiation without affecting the transmittance of the GREEN spectrum, and retains cool, diffused GREEN light.
