Zip-Shield® (PFR)
  • PFR jacketing is 18 Mil in thickness, offering resistance to abrasion and most fluids
  • Pressure track closure system for a secure seal
  • EMI shielding cloth is lightweight and corrosion resistant

 Zip-Shield® (PFR) is an EMI shielding solution consisting of a wraparound PFR jacket with a sewn-in shielding cloth and a pressure track. The highly flexible PFR-18 material is flame retardant and military grade as well as resistant to abrasion and most fluids. The jacketing is also non-PVC, which makes it good choice for many nuclear, aerospace and military applications where PVC materials are not permitted. The 3250 EMI shielding cloth offers protection from EMI, RFI, and EMF, so you can be confident that your components will not be compromised by these damaging interferences.

Zip-Shield® (PFR) is typically paired with the R-Track or the Z-Track. These pressure track systems are easy to seal and offer a long-lasting closure. If re-entry is required, you can easily break out components. The R-Track is a light-duty pressure track closure and is similar to a zip-lock closure. The R-Track can be sealed manually with a thumb or with an SLR slider tool. The Z-Track is a medium-duty pressure track closure with an arrowhead and channel interlock system, and it is the most versatile pressure track option. The Z-Track can be sealed with our ZTZ-SP plier tool. Zippertubing® can also manufacture Zip-Shield® (PFR) with our other pressure track closures upon request.
