McHenry, IL - Those who make and use diffusers to eliminate the hot spots caused by light emitting diodes (LEDs) in such applications as signage, light bulbs and illuminated knobs can turn to a new line of diffusion masterbatches from Chroma Corporation to improve efficiency and brightness. These concentrates offer a significant savings over their precompounded counterparts.
Chroma Corporation developed its light diffuser masterbatches using a polymer-based diffusion additive specially formulated for polycarbonate, acrylic and other clear plastics. These masterbatches provide for greater light transmission than traditional mineral-based light diffusers.
Traditional LED diffusers contain fine particles of a mineral like calcium carbonate, barium sulfate or titanium dioxide, which absorbs light allowing less light to transmit out. Chroma's new products contain proprietary spherical polymer particles that scatter and spread light in plastic sheets, molded specimens and films to form an even illumination, while allowing light transmission levels of 94 percent or more.
"LED use is increasing because these light sources are energy efficient, operate at relatively low temperatures and last for many years," says Stu Swain, Director of Sales and Marketing "Our new line of concentrates offer a way to make fuller use of LEDs in channel signs, automotive buttons and knobs, crowns for light bulbs and illuminated switches and key pads on electronic devices. It can make any device using this light source more efficient, so manufacturers can offer brighter products or install fewer LEDs in an array for the same illumination."
Chroma offers its light-diffusion masterbatches in conjunction with color pigments or dyes, UV stabilizers and all other additives needed for an interior or exterior application. The diffusion masterbatch is typically used at a rate of 3 to 6 percent, depending on the level of diffusion needed and the thickness of the part.
Founded in 1967, Chroma Corporation is a global thermoplastic-compounded raw material leader. Product offerings include the broadest range of custom color, special effect, and specialty additives in masterbatches and precompounded products in commodity and engineering thermoplastic resins. Materials are designed for extrusion, injection molding, blown film and a multitude of other processes and applications including rotational molding.
