Material for Micro-Tec CT carbon fibre reinforced PVDF ESD safe plastic probes
The material used for manufacturing the Micro-Tec CT series ESD safe plastic probes is polyvinylidene fluoride (PVDF) reinforced with 30% carbon fibre.
It is used for the following products:
#52-001050 Micro-Tec CT1 carbon fibre reinforced PVDF probe, fine pointed / strong flat
#52-001051 Micro-Tec CT2 carbon fibre reinforced PVDF probe, curved pointed / strong flat
#52-001052 Micro-Tec CT3 carbon fibre reinforced PVDF probe, sharp flat / large flat
#52-001053 Micro-Tec CTS carbon fibre reinforced PVDF probes, set of all three
General remarks:
- CT series is plastic polyvinylidene fluoride (PVDF) reinforced with 30% carbon fibre
- ESD safe material (avoid powder or dust attraction, avoid spark generation)
- smooth surface
- excellent mechanical strength and toughness
- heat stabilised, high heat capacity with a continuous use temperature of 150°C
- high purity (clean room and medical devices approved; low extraction value)
- high abrasion resistance
- cryo compatible material
- excellent chemical resistance to most aggressive substances (mineral and organic acids), solvents (hydrocarbons, alcohols, halogenated) and halogens
- outstanding resistance to hydrofluoric acid (40% conc. / 90°C), nitric acid (50% conc. / 90°C) and hydrochloric acid (36% conc. / 90°C)
- resistant to UV and nuclear radiation (compatible with this sterilisation)
- typical applications include tweezers for handling scratch and contamination sensitive components, sample processing with chemicals, cleaning and etching processes.
