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
