Dimensional Stability:
Glassfiber Filter cloth has low elongation under load, generally 3% or less. Glass fibers produce fabrics with excellent dimensional stability under various types of conditions.

High Heat Resistance:
Glassfiber filter cloth has excellent heat resistance at relatively low cost. Glassfiber cloth retains approximately 50% of room temperature tensile strength at 700F (371C); approximately 25% at 900F (482C); with a softening point of 1555F (846C) and a melting point of 2075 F (1121 C).

Fire Resistance:
Glassfiber Filter cloth is composed of inorganic materials, and are noncombustible, a natural choice where flammability is of concern.

Good Thermal Conductivity:
The rapid heat dissipation of Glassfiber cloth is particularly important in electrical insulation applications.

Good Chemical Resistance:
Like glass itself, Glassfiber cloth is highly resistant to attack by most chemicals.

Outstanding Electrical Properties:
Glassfiber fabric withstands high temperature and has low moisture regain. Along with its high dielectric strength and low dielectric constant, glass is of major importance and usefulness in the electronics.

Durability:
Being inert, Glassfiber cloth is unaffected by sunlight, fungus or bacteria.

Economical:
Glassfiber Filter cloth is lower in cost than many other fabrics for similar applications.
