FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

How does an ESD-protected silicone jacket prevent electrostatic damage and particle attraction in a cleanroom?
Standard insulating cable jackets (surface resistance > 10¹² Ω) accumulate triboelectric static charges up to several kilovolts when flexed or wiped with isopropanol. Those charges both attract sub-micron airborne particles onto the cable and risk ESD discharge into sensitive wafers or OLED panels. Besilen ESD Control Cable uses a dissipative silicone jacket (10⁴–10⁷ Ω) that bleeds charge continuously to ground.
How must the antistatic outer sheath be grounded during installation?
To drain static charge into the equipment earth, clamp the outer black ESD silicone jacket inside a conductive metallic cable gland or conductive ESD clip bonded to the grounded machine frame.
Why choose Besilen ESD Silicone over SABclean S 776 / S 780 C TPE/PUR cleanroom cables?
Choose Besilen ESD when you need either (a) active electrostatic charge dissipation per DIN EN 61340-5-1 or (b) thermal endurance up to +180 °C (autoclave sterilization, wafer bake plates, thermal chucks). For high-cycle room-temperature drag chains (-40 to +80 °C), choose SABclean S 776 / S 780 C.
Is the cable free of talc and chalk separating powders?
Yes. Standard rubber cables use talcum powder inside the jacket to prevent core sticking, which contaminates cleanrooms when the jacket is stripped. Besilen ESD uses a non-shedding fluoropolymer/fleece release wrap instead of powder.
