Super smooth carbon tabs and tapes

Super-smooth high purity double sided conductive adhesive carbon tabs and tapes have been especially developed for imaging and analysis applications of fine powder and fibre specimens. The adhesive material used for the tabs and tapes is fully transparent for EDS analysis with only trace amounts of Al and Si. The material is constructed using a super-smooth aluminium foil coated on both sides with a conductive, carbon-filled pressure sensitive acrylic adhesive. The result is a super-smooth surface combined with high conductivity. Total thickness of the material is approximately 110µm with an adhesive thickness of 40µm on each side. The adhesive exhibits a high adhesion strength to metals, plastics, ceramics, wafers, rubber, wood, glass, paper, and small particles or fibres.

Super-smooth double-sided carbon tapes:

  • Super-smooth thin material; 110µm total with 40µm adhesive on each side of the aluminium foil carrier
  • Highly conductive
  • Excellent for fine powders and small fibres
  • Ideal for automated EDS particle analysis
  • Use temperature range -20°C to + 60°C
  • Low outgassing rates
  • Fully EDS transparent high purity for EDS applications
  • High strength thin adhesive (2 x 40µm) combined with high tack
  • Long shelf life and can be stored in a refrigerator

Super-smooth, conductive, double-sided adhesive carbon tabs

EM-Tec super smooth conductive double-sided adhesive carbon tabs are supplied on a clear plastic sheet with easy lift-off plastic liner tabs. Available as Ø12mm and Ø24mm carbon tabs.

To use: lift the tab of the clear backing sheet, press the sticky surface to the mount, then remove the easy lift-off white liner tab, leaving the adhesive exposed. Mount specimens on the exposed adhesive. Alternatively, the white easy lift-off liner tab can be removed, the stub pressed on the exposed carbon tab and the clear plastic lifted off. Carbon tabs can be easily removed with isopropanol, ethyl acetate, ethanol or acetone.

  • Ø12mm carbon tabs are compatible with Ø12.7mm pin stubs, Ø12.2mm JEOL stubs and Ø15mm Hitachi stubs
  • Ø24mm carbon tabs are compatible with Ø25.4mm pin stubs, Ø25mm JEOL stubs and Ø25mm Hitachi stubs

Super-smooth, conductive, double-sided adhesive carbon tabs

The material is identical to that used for super-smooth carbon tabs, with one difference – the tapes are self-wound with a thin white liner on one side of the tape. The tape can be shaped into custom forms, strips and cut-outs. Available with 5mm, 8mm, 12mm and 20mm width by 20m long.

To use: cut the required length of carbon tape. Cut to shape if needed. Remove the white liner from one side and adhere the tape to the specimen support. The use of sharp pointed tweezers helps to lift the liner of the adhesive. Remove the top liner and stick the specimen to the tape. Carbon tape can be removed using isopropanol, ethyl acetate, ethanol or acetone.

If smoothness of the surface is not a requirement, then the lower cost, high purity carbon tapes are an excellent alternative.
