Aluminum Foil Coated Fiberglass Sleeve with Velcro Hook & Loop Closure
High Temperature, Heat Resistant & Radiant Heat Reflective
Heat Reflective Sleeve
1000°F / 537°C Peak Exposure:
450°F / 232°C Continuous
This high temperature, heat resistant and radiant heat reflective sleeve can be used to protect wires, cables, hoses (hydraulics), piping and tubing from radiant heat sources such as glowing steel slab, liquid metal pour stream, infrared heaters and other similar sources.
First, a layer of highly polished aluminum foil is calendared under high pressure and with an adhesive onto a high temperature fiberglass base fabric. That fabric is slit into an tape, which is then sewn with a velcro hook and loop closure, allowing it to be used as a removable sleeve.
The fabric can also be fabricated into a sleeve with Velcro hook and loop closure, to result in a removable sleeve.
This aluminized sleeve reflects more than 95% of the radiant energy that hits its surface, keeping the underlying cables, hoses and wires cool.
Available in sizes from 1/2" through 12" ID. Larger sizes are available with a seam construction.
Two weights of fabric are used to make these sleeves: a 21oz and a 35oz. The 21oz material has better aluminum adhesion for applications requiring some flexing The 35oz material will have some random and occasional small surface flaws, typically smaller than 1/4" square, where the aluminum surface may be cracked or lifted from the substrate or void; this is normal for this material as part of the sleeve fabrication process.
A four layer aluminum coated fabric is available. This fabric is more robust, but quite stiffer than a single layer aluminum coated fabric.
Generally, aluminum foil coated fiberglass is suitable for applications involving static hoses, cables and wires. For installation where continuous movement or flexing is involved, an aluminum-mylar-aluminum coating applied to the fiberglass is more suitable. Also available is a solid annular stainless steel sleeve.
The reduced continuous temperature limit of this material is due to the adhesive used to help bond the aluminum foil layer to the fabric. Notwithstanding the temperature limit, intense radiant heat can be reflected while still under the continuous temperature limit.
