Hook-N-Shield® (TPU)

An EMI shielded, white, halogen-free, flame-retardant, thermoplastic polyurethane hook-and-loop solution.

Hook-N-Shield® (TPU) provides one of the best ways to obtain a clean, white appearance on the outside while offering a hook-and-loop closure and EMI shielding on the inside. EMI shielding is important for many applications, but this particular solution is not just an EMI shielding solution; it also offers halogen-free and flame-retardant properties.

This product utilizes:
  • TPU Jacketing
  • Aramid Hook-and-Loop
  • Braided Ground Strap
  • Nomex Sewing Thread
  • Z-7200-C EMI Shielding Cloth

Zippertubing® offers two types of fully halogen-free EMI shielding with the Hook-N-Shield® (TPU) solution, which includes our SHX mesh and our Z-7200-C cloth. Z-7200-C offers superior EMI shielding, while the SHX mesh provides a durable and conductive EMI shielding layer.

Because of the way that this product is engineered, it’s also a great solution for applications in which higher-temperature environments are likely to impact cables or wires.

Although this Hook-N-Shield® (TPU) is not specifically manufactured using a clean room in sterile conditions, with the right procedures, it could be used in the medical field, including in hospitals, operating rooms, trauma centers, and emergency rooms.
