Fiberglass filter cloth is a material commonly used to filter and separate solid particles in industrial processes. It is made of fiberglass and has excellent chemical stability, high temperature resistance, corrosion resistance and mechanical strength. This makes fiberglass filter cloth widely used in many industries, such as chemical industry, petroleum, pharmaceutical, water treatment, metal processing, etc.

Characteristics of Fiberglass Filter Cloth

  • High temperature resistance.
  • Dust peels off easily.
  • Good dimensional stability and almost zero shrinkage.
  • It has good chemical resistance and is stable to other media except hydrofluoric acid, strong acid and strong alkali.
  • Does not absorb water or moisture.

Our Advantages

  • High-quality fiberglass yarn: Our selected 6μm fiberglass yarn with high strength, high stiffness and corrosion resistance.
  • Advanced production equipments: Filmedia is equipped with advanced jet looms, rapier looms and warping machines to ensure the stable and high qualified media We produce.
  • Strict quality inspection: Finally, the processed fiberglass filter cloth will undergo quality inspection. This includes inspecting the appearance, size, strength, filtration performance, etc. of the fabric to ensure it meets design requirements and application standards.

Finish Treatments

We independently designed and developed special equipment for desizing and PTFE impregnation ensuring efficiency and reducing the unqualified rate of the two processes:

  • PTFE membrane: Our laminating machine uses imported high temperature heating roller. The roller surface temperature tolerance is ±1 ℃ ensuring the film fastness and uniformity. PTFE membrane thickness is 15um. The max membrane width can be 2.2M.
  • PTFE impregnation, PTFE membrane, Anti Acid, Silicon+Graphite+PTFE treatment.
