- 4 1/2″ – 115 mm.
- Straight, very fine, sharp tips.
- Suitable to applications which require holding a very fragile and very small component. The Carbon Fiber reinforced ESD Plastic provides the tweezers with ESD and non-scratching properties.
Engineering plastic – CARBON FIBRE (CF).
- PA66/CF30 – polyamide 66 reinforced with 30 wt% carbon fibre.
- ESD safe material, lead-free.
- High mechanical strength and toughness.
- Low friction, self lubricating properties, excellent wear and abrasion resistance.
- Heat stabilized, 130°C (continuos use) – 190° (short time).
- Very low coefficient of linear thermal expansion.
- Very high rigidity, excellent tensile and flexural strength (bend strength), fatigue and creep resistance.
- Good chemical resistance (oils, grease, fuels, non polar solvents), but not resistant to strong acids, alkalis, hot water or steam.
- Applications include handling of sensitive components and devices (electronic components, micro-mechanical parts, glass and ceramic substrates, etc.) where non-scratching is critical. Popular in standard ESD and general electronics assembly and lab applications.
High performance plastic – PVDF (SV).
- PVDF – polyvinylidene fluoride carbon fibre reinforced.
- ESD safe material, (avoid powder attraction, sparks generation, ignition sources).
- Smooth surface, excellent mechanical strength and toughness.
- Heat stabilized, high heat capability, continuous use temperature up to 150°C.
- High purity (clean room and medical devices approved, low extraction value).
- Excellent chemical resistance to most aggressive substances (mineral and organic acid) and solvents (hydrocarbons, alcohols, halogenated), resistant to halogens.
- Outstanding resistance to hydrofluoric acid (40% conc., 90°C), nitric acid (50% conc., 90°C), hydrochloric acid (36% conc., 90°C).
- High abrasion resistant.
- Resistant to UV and nuclear radiation (sterilisation).
- Typical applications include handling of very scratch- and contamination-sensitive components, cleaning and etching processes.
Engineering plastic – WHITE DELRIN (DG).
- POM/GF30 acetal resin reinforced with 30 wt% glass fibre.
- Good tensile and flexural strength, fatigue and creep resistance.
- Low friction, good wear and abrasion resistance.
- Low moisture absorption and insulating.
- Good chemical resistance (oils, grease, fuels, organic solvents); not resistant to strong acids, alkalis and oxidizing agents; good hydrolytic resistance (hot water).
- Typical applications include handling of very scratch sensitive components (ceramic and glass devices, wafers, capillary).
