Display

Advanced Specialty Polymer

LCD Light diffusion film and plate

  • Narrow Particle Size Distribution Gives High Luminance
  • Excellent diffusion effect with higher transmittance
  • Almost Parallel Light [Important for LCD Backlight Unit]
  • Easy Dispersion in Solvents and Waterborne and Excellent Solvent & Weather Resistance
