Technical Data Sheet: Engineering Plastic Type “CF”

General Notes:

• PA66/CF30 Polyamide 66 reinforced with 30 wt% carbon fiber heat stabilized
• Very high rigidity, excellent tensile and flexural strength, fatigue and creep resistance.
• Low friction, self lubricating properties, excellent wear and abrasion resistance.
• Good heat capability.
• Good chemical resistance (oils, grease, fuels, non polar solvents): not resistant to strong acids, alkalis and hot water or steam. For higher heat resistance and chemical compatibility see our “CP” PEEK Tweezers Line.
• ESD Safe Material, very low surface resistivity.
• Very low coefficient of linear thermal expansion.
• Typical applications include handling and positioning of electronic components and devices, where an optimal balance between stiffness and surface smoothness is required.
