Glass fiber filter paper

Features
  • Uniform texture, double-layer filter material structure, layered filtration;
  • Stable chemical and physical properties and strong corrosion resistance;
  • High filtration efficiency and low resistance;
  • Large specific surface area and high dust capacity;
  • High hydrophobicity, excellent water and moisture resistance;
  • Large expansion strength and high filter material stiffness;
  • The fluctuation of banner quantitative and vertical quantitative is very small;
  • High temperature resistance, can be used in high temperature environment within 300 ℃.
Applications
It is the raw material for the production of diaphragm filter, non diaphragm filter, combined filter and high-efficiency HEPA filter.
