Glass Microfiber

The unique properties of Unifrax Glass Microfiber products allow nonwovens producers to engineer superior products and solutions for high-efficiency filtration media, Absorbent Glass Mat (AGM) battery separator, and numerous other air and liquid filtration/separation applications. Utilizing the fine diameter, high specific surface area (SSA) and chemical properties of our fibers, our customers can optimize pore structure and mechanical properties of their specialty nonwovens.

Unifrax Glass Microfibers have the following outstanding characteristics:

• Broad product range: Average fiber diameters from 0.25μm – 5.0μm
• High tensile strength, low shot, consistent glass chemistry and purity High specific surface area (SSA)
• Long length to diameter ratio (L:D)
• Multiple glass chemistries: A, B, C & E-Glass
• Multiple fiberizing technologies available

Typical applications:

• Filtration media
• Battery separators
• Analytical papers
• Respirators and personal safety devices
• Fiber Reinforced Plastics (FRP)
• Surfacing veils
• Friction & absorbent materials
• Catalyst supports
• Cryogenic insulation
