Zipper-Mesh^™ (ALHTG-65)

ALHTG-65 is a heavy weight, .065" thick, mechanically bonded glass fiber cloth treated with a proprietary coating and laminated on one side with Aluminum Foil for high temperature applications up to 1,202°F (650°C). The base cloth material will stand short-term exposures as high as 1,650°F (899°C). ALHTG-65 is manufactured from long textile glass fibers and contains no binders, thereby, assuring insulation efficiency during extended periods of elevated temperatures; even with direct exposure to fire. The material does not contain Asbestos and has no heavy metal additives.

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.

Ground wires normally allow an electrical connection or transfer of the electromagnetic interference (EMI) from the component to a grounded connector. Zippertubing offers many different gauges of ground wires to meet the needs of your application.

Our ground wires are comprised of tin-plated, copper-wire that are braided and formed into a flat configuration. They are used as an electrical ground drain, confirm to Federal Specification QQ-W-343E and American Society for Testing and Materials ASTM-B-575B specifications.

Brass toothed zippers consist of individual brass metal interlocking teeth attached to a separating Aramid 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. Brass 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. Brass toothed zippers can be used in very large size applications by increasing the tooth size. Brass toothed zippers are stronger than molded toothed zippers and more immune to damage. However, unlike plastic zippers they do not have a "self-lubricating" quality and may require periodic lubrication to operate smoothly. Ideally all zippers should be used in applications that are free of dirt and debris which could cause jamming. Brass zippers can be cleaned with a small brush if contaminated and they are prone to corrosion unlike plastic zippers. 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. Available with optional black oxide tooth finish.
