Glass Microfibre

The unique properties of Unifrax Glass Microfibre products allow non-woven producers to engineer superior products and solutions for high-efficiency filtration media, Absorbent Glass Mat (AGM) battery separators and numerous other air and liquid filtration/separation applications. Using the fine diameter, high specific surface area (SSA) and chemical properties of our fibres, our customers can optimise the pore structure and mechanical properties of their speciality non-wovens.

Unifrax Glass Microfibres have the following outstanding characteristics:

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

Typical applications:

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