New TPU Material Enhances EMI Protection for Medical and Cleanroom Applications

Electromagnetic interference (EMI), radio frequency interference (RFI), and electromagnetic fields (EMF) continue to challenge sensitive electronic equipment across industries. In environments where signal purity and operational safety are paramount—such as medical facilities and cleanrooms—these disturbances can compromise device functionality with potentially serious consequences.

Engineering Excellence: The Foundation of Superior Shielding

Hook-N-Shield® (TPU) delivers exceptional shielding performance through its multi-layered construction. At its core lies the SHX-4 (SnCuFe) shielding mesh, featuring a four-layer tin-plated copper-clad steel braid. This specialized material composition provides effective attenuation across both high and low frequency interference spectra.

For enhanced protection, the system offers optional high-performance shielding fabrics: Z-3250-CN, a copper-nickel electroplated taffeta with superior corrosion resistance, and Z-7200-C, a non-magnetic, halogen-free alternative ideal for magnetically sensitive instruments and halogen-restricted environments.

TPU Outer Layer: Durability Meets Safety Standards

The 0.02-inch thermoplastic polyurethane (TPU) outer jacket combines mechanical resilience with stringent safety certifications. Demonstrating Stage 0 ozone resistance ("no cracking") and UL 94 V-0 flame retardancy, the halogen-free material meets the exacting requirements of medical, aerospace, and cleanroom applications where material safety and environmental compliance are critical.

Innovative Closure System: Installation Efficiency Redefined

The hook-and-loop closure system, constructed from aramid fiber, enables tool-free installation and maintenance. The design allows rapid deployment around cables with secure fastening, while maintaining easy access for component inspection or replacement. Aramid stitching ensures closure integrity while preserving the system's halogen-free properties.
