Zipper-Mesh^™ (PFR)

PFR-18 is an extremely flexible, flame-retardant polyether urethane material that has a soft rubber-like texture. PFR-18 jacketing offers exceptional ruggedness, resistance to abrasion and most fluids, while exhibiting high flexibility in virtually any demanding environment. The material meets Mil-I-3930/21 specifications and is an excellent choice for many nuclear, aerospace and military applications where PVC materials are not permitted. PFR-18 can be configured for round, flat and rectangular cable configurations and can be combined with most Zippertubing EMI Shielding materials.

SHX-4 (SnCuFe) is a flexible 4 layer knitted wire mesh EMI shielding material that is made of Tin plated, Copper clad Steel wire. The knitted mesh design creates a highly flexible shield that unlike many tubular braids will not change attenuation performance when articulated. The knitted wire mesh maintains constant window spacing during cable assembly movement and as a result yields excellent EMI shielding performance from 500 KHz through 1 GHz. The material is highly conductive, rugged and is ideal for airborne applications where lightning strike grounding is required. The mesh can be added to most Zippertubing jacket materials to create an easy to install Zip-On EMI shielded assembly. SHX-4 shields come with a standard 15 AWG drain wire attached to simplify grounding.

Toothed zippers consist of individual molded Delrin® interlocking teeth attached to a separating Polyester fabric tape which has a fixed start and stop point. The zipper is closed via a self-locking slider which make a zipper installation tool free. Toothed zippers are available as a medium or heavyweight, highly flexible, closure system for cables where a tool-free installation is desired and the open/closure cycle frequency is likely to be high. Toothed zippers perform best in round cable applications where the cable bundle diameters exceeds 1.0 inch and larger and on flat ribbon cables over 2.0" wide. Toothed zippers can be used in very large size applications by increasing the tooth size. Ideally all zippers should be used in applications that are free of dirt and debris which could cause jamming, however toothed zippers are easily cleaned with a small brush if contaminated. For smaller cables and lightweight applications use a "coil zipper" style. Zippers cannot be cut to length on site at the time of installation so assembly length must be known at the time of order. Zippers items are typically commercial items and meet the manufactures performance specification; however they can be procured in compliance to A-A-55634.
