Media Features

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

Dimensional stability

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 500oF (260oC)
