Both items are supplied as impulse sealing technology accessories.
3E is able to supply the following standard sized steel alloy bands:
• widths from 1.5mm to 10mm
• thicknesses from 0.1mm to 0.3mm
3E is able to supply steel alloy bands having the following sections:
• with T-profile
Special bands can be manufactured according to the customer’s specific requirements. For any further information or non-standard measurements, please contact our sales office.
3E is able to supply steel alloy wires with standard diameters ranging from 0.8mm to 1.2mm. For any further information or non-standard measurements, please contact our sales office.
• Working temperature: DO NOT exceed 200°C to avoid mild thermal drifts
• Specific resistance: at 20°C 0.730 [ohm x mm² / mt]
• Specific resistance: at 200∞C 0.850 [ohm x mmq / mt]
• Temperature coefficient: 913 PPM / K
Notes and additional information
In order to obtain repetitive working temperatures, it is advisable to sheathe the bands and wires with copper or silver at their ends, outside the sealing area, up to the electrical – mechanical connection terminals.
You can also coat the bands and wires with Teflon. For this type of application, please contact our technical department.
Use and Application
Both steel alloy bands and wires can be heated by impulse thermoregulators to accelerate heating times and consequently to speed up sealing at very high temperatures. In this case it is essential to apply the copper plating or silver plating treatment.
