Materials of anti-static heel straps(Ready stocks)
The materials of anti-static heel straps are mainly composed of the following three parts:
Conductive rubber
As the core buffer layer for static electricity conduction, it is usually made of synthetic rubber material with a surface resistance range of 10³-10⁶Ω. The black contact layer directly contacts the skin or socks to achieve charge conduction. Some products use a stitching process to fix the conductive rubber layer to the sole to form a complete static electricity release path.
Conductive webbing
The woven strap that is in direct contact with the ankle/instep of the human body is usually made of conductive fibers (such as ESD materials embedded with metal wires). The webbing is responsible for collecting human static electricity and transferring it to the conductive rubber layer, and finally introducing it into the anti-static floor. Its resistance to ground with the conductive rubber must meet the 10⁶Ω standard.
Adjustable Velcro
Velcro using injection hook technology is used to fix the webbing and adapt to different foot shapes. Its functions include:
Providing a length adjustment function to ensure that the webbing is in close contact with the skin;
Maintaining the stability of the conductive path to avoid static electricity conduction failure due to looseness. In special application scenarios (such as wearing high heels), the toe strap will use a combination of thinner conductive rubber and woven tape, but the core material is the same as the heel strap.
