Zip-Shield® (3250) is an EMI shielding solution consisting of a jacket with a sewn-in shielding cloth and a pressure track. Zippertubing® offers a wide range of jacketing options for your unique application requirements, whether you need a jacket that is military grade and flame retardant or one that is PVC free and provides exceptional abrasion resistance. 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.
If you require an EMI shielding cloth that is non-magnetic, Zip-Shield® (7200) is also available. If you require shielding for lower frequencies, Zip-Shield® (SHX4) would be the ideal choice, and if you require shielding for higher frequencies, Zip-Shield® (SH1) would be the ideal choice.
Zip-Shield® (3250) 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, and if re-entry is required, you can easily break out components. 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. 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.
Zippertubing® can also manufacture Zip-Shield® (3250) with our other pressure track closures upon request.
Jacketing options for Zip-Shield® (3250) include:
63-10: Flexible and lightweight PVC film that is military grade, abrasion resistant, and fluid resistant.
63-20: Flexible and medium weight PVC film that is military grade, abrasion resistant, and fluid resistant.
PFR-18: Extremely flexible polyurethane film that has excellent abrasion and fluid resistance and is military grade and flame retardant.
PVL-10: Extremely flexible and lightweight woven polyester fabric that has a PVC coating in addition to high tear strength and abrasion protection.
VNH-23: Extremely flexible and medium weight nylon fabric that has a PVC coating and is military grade, flame retardant, and provides durable protection for applications in rugged environmental conditions.
DVH-20: Durable polyester fabric with a PVC coating that is flame retardant, abrasion resistant, and ideal for applications in which components may be exposed to harsh outdoor conditions.
DVH-40: Heavy duty polyester fabric that has a PVC coating and is extremely tough for rugged conditions, such as industrial applications in which abrasion and tear resistance are required.
NET-30: Medium weight jacket made of woven polyester fibers with a PVC coating that is flame retardant and abrasion resistant and allows air or water to pass freely through the jacket for applications with such requirements.
RPU-17: Flexible and medium weight white polyurethane and polyester fabric jacketing that is tear resistant and flame retardant.
