Low surface resistance through nanotubes
Our ESD material is modified through nano technology and equipped with carbon nanotubes, among other things. Carbon nanotubes are used as a functional filler. Due to their graphitic surface structure they have a high electric conductance. Cable carriers made from this material have a surface resistance of ≤ 10 5 Ω which far exceeds the values required by the ESD standard. Carbon nanotubes have a diameter of only a few nanometers and a length of up to a few millimeters.
Cable carriers with nanotubes ■ ■ Low surface resistance: ≤ 10 5 Ω ■ ■ Significantly exceed the values required by the ESD standard ■ ■ Areas of application: chip handling, semiconductor manufacturing, electronics manufacturing, solar technology
Higher conductance of the complete cable carrier
The large specific surface and the extremely even distribution of the nanotubes in the material achieves good conductance even at the contact points between the chain links and therefore across the entire cable carrier length. A resistance of ≤ 10 5 Ω was mea- sured on a KABELSCHLEPP cable carrier of type ET 0320.025.030.038 with a length of 125 links (= 4 m).
Quality with factory certificate Each ESD cable carrier with nanotubes technology is supplied with a KABELSCHLEPP factory certificate to certify its quality.
High stability
High conductance even after one hundred thousand movement cycles The test shows that the surface resistance of the com- plete cable carrier decreases during the running-in phase and then remains constant at 10 Ω.
The modification of the fiberglass-reinforced material with nanotubes makes the cable carriers even sturdier. The nanotubes have a sixth of the weight of steel but their tensile strength is multiple times higher. This also increases the mechanical properties while retaining the high elasticity of the cable carriers made of ESD material. This effect is also applied successfully in numerous sports equipment, e.g. tennis rackets, bicycles and golf clubs.
