ALCOM® LDDC PMMA 1000UV18123 BK1016-11

MOCOM Compounds ALCOM® LDDC PMMA 1000UV18123 BK1016-11 is a translucent, UV stabilized Polymethylmethacrylate polymer used for Automotive, Lighting, and interior decoration/finishing, light transparent components, and Black Panel-Technology applications such as lamp covers, display elements, and operating elements. Pre-drying conditions involve 80°C in a dry air (dessiccant) dryer for 3-4 hours and 80°C in an air circulating dryer for 4-6 hours with a maximum moisture content of less than 0.02%. For processing injection molding, the melt temperature should be between 220-270°C and the mold temperature should be between 50-80°C. It should be protected from light.

Technical Details & Test Data

Product Performance Characteristics

Alcom® LDDC – Deep Color
 

  • Deep Color for illuminated parts
    • Optical appearance in deep colors (e.g. “Piano Black”) when backlight LEDs switched off
  • Optimized transmission of (colored) LED light
    • Symbols or displays visible, when LEDs are switched on
    • No visual color shift of transmitted light
  • Transmission with/without homogeneous scattering
    • Tailor made: Color, transmission, haze, half power angle
  • Suited for illuminated applications
    • Seamless user interfaces
    • Decorative elements, consoles
  • Displays, touch sensitive surfaces

​​​​​​​

Example: Cover Lens for Displays

  • Transparent black material covers display unit
  • Mold-in-Color user surface
  • Display on: clear transmission
  • Display off: deep gloss black panel
  • Electronics not visible

Example: Classic Ambient Lighting
 

  • Piano black diffusing lens
    • Homogeneous light output
  • Established assembly concepts
  • Can be implemented into seamless designs

Also, for ambient lighting of larger areas, e.g.

  • Illuminated door trim
  • Illumination of center console

​​​​​​

Pre-Drying Conditions
  • 80 °C in a dry air (dessiccant) dryer for 3-4 h
  • 80 °C in an air circulating dryer for 4-6 h
