It's woven fiberglass, so inherently flame resistant.Lucky to be working in the theater this week, however we're unlucky that the reason is our theatre flooded.
Our Z-tek fiberglass heatsheild got soaked, couple of 60' lengths . Is it inherently Heat/Flame resistant or would the water have damaged its head-shielding properties?
Thanks
It appears that the vermiculite coating adds to the heat resistance, but the fiberglass fabric itself is inherently heat resistant. From the website: https://www.newtex.com/npm/fabrics/zetex-fiberglass-fabric
Zetex® fiberglass fabrics are widely used for thermal insulation, acoustic insulation, and for protection from heat and fire. These woven fiberglass fabrics support operating temperatures up to 1000°F / 540°C and peak temperatures up to 1300°F / 700°C. They are inherently heat and flame retardant fabrics made from inorganic materials so they will not produce hazardous out-gassing.
- Vermiculite Coating: The proprietary ZetexPlus® vermiculite coating increases the operating temperature resistance of the fiberglass fabric to 1500°F (815°C) and peak temperature resistance to 2000°F (1095°C). This high-temperature coating also improves abrasion resistance. ZetexPlus® vermiculite coated fiberglass fabrics are commonly used in fire curtains, fabric expansion joints, and pipe or tank insulation systems.
That material was then known as Daco. Now it is nylon reinforced vinyl under a couple of trade names. It's available in different weights. I'm not sure I would recommend it now unless the temps were under 250/300 degrees. We use and sell Weldflex these days. Black finish fiberglass.Does all Zetex have this vermiculite coating? I can understand its use in a fire curtain, but as an electric border that may get moved around and handled a lot--not so much.
A hundred or so years ago, when I desired "asbestos borders" for my electrics, @Ted jones recommended a material normally used in gym divider curtains: much less expensive and easier to sew. Never had any problems; was very pleased.
