Pomalux SD-A (Static-dissipative acetal copolymer) Non-carbon-filled, permanently staticdissipative material which is non-migratory and non-humidity dependent. With enhanced lubricity, Pomalux SD-A provides superior wear resistance and ease of machining. Its extremely low outgassing values and non-sloughing characteristics make it ideal for applications where particulate generation cannot be tolerated. Enhanced lubricity, chemically resistant, and dimensionally stable.

Advantages:
  • Low outgassing
  • Consistent resistivity values
  • Ease of machining
  • Good chemical resistance

Applications:
  • Disk drive assembly fixtures
  • Semiconductor/electronic components
  • Telecommunication hardware
  • Automotive equipment
