HL Filter offers woven fiberglass fabrics, additionally laminated with an ePTFE membrane, with excellent tensile strength, high heat resistance, low weight, and great cosmetics. Fiberglass Fabrics are woven for fiber orientation, and each fabric features its own unique weight, strength, and fabric characteristics.
Bulk Roll Goods: weight, thickness, density, roll width, and roll length are customized at your request.
Fiberglass has excellent resistance to most acids, but is attacked by hydrofluoric acid
Not recommended where bases and salts such as chlorides, bromides, and cyanides are present
Poor flex abrasion qualities
High tensile strength
High heat resistance, good thermal conductivity, and fire resistance
Outstanding Electrical Properties
Unaffected by sunlight, fungus or bacteria.
Finishes limited, maximum temperature range.
Glass fabrics are lower in cost than many other fabrics for similar applications.
Requires a 20 vertical wire minimum support cage when used in tubular filter bag form
Usually used in high heat applications. Continuous operating temperature of 500℉ (260℃)
