Material for EM-Tec CN carbon fibre reinforced polyamide ESD safe plastic tweezers

The material used for manufacturing the EM-Tec CN series  ESD safe plastic tweezers is a Polyamide 66 (Nylon66) reinforced with 30% carbon fibre.

It is used for the following products:

#50-012702 EM-Tec 702A.CN ESD safe PA66/carbon fibre reinforced tweezers, blunt tips
#50-012705 EM-Tec 705.CN ESD safe PA66/carbon fibre reinforced tweezers, fine tips
#50-012707 EM-Tec 707.CN ESD safe PA66/carbon fibre reinforced tweezers, sharp tips
#50-012708 EM-Tec 708.CN ESD safe PA66/carbon fibre reinforced tweezers, sharp angled tips
#50-012709 EM-Tec 709.CN ESD safe PA66/carbon fibre reinforced tweezers, flat tips
#50-012710 EM-Tec 710.CN ESD safe PA66/carbon fibre reinforced tweezers, flat thin tips
#50-012717 EM-Tec 707A.CN ESD safe PA66/carbon fibre reinforced tweezers, sharp curved tips


General remarks:

  • CN series is the engineering plastic polyamide 66 (PA66) reinforced with 30% carbon fibre
  • ESD safe material (avoid powder or dust attraction, avoid spark generation)
  • heat stabilised and good heat capacity
  • Very high rigidity, excellent tensile and flexural strength
  • good fatigue and creep resistance
  • low friction and self lubricating properties
  • excellent wear and abrasion resistance
  • good chemical resistance against oils, grease, fuels and non-polar solvents. Not resistant to strong acids, alkalis, hot water or steam
  • very low coefficient of linear expansion
  • Typical applications include tweezers handling of sensitive components, devices and samples in laboratory, assembly and manufacturing
