Glass Fiber Membrane Filter 
Glass-Microfiber-Filters cbt.png

The glass fiber has a round cross-section and a constant diameter, and can be made very fine, with a high dimensional stability and high porosity. Therefore, the paper made from it has high tensile strength, good chemical stability, water resistance, oil resistance, acid and alkali resistance, corrosion resistance, high temperature resistance up to 500ºC, low thermal conductivity, sound absorption, and has good permeability, high load capacity and other excellent characteristics.

Cobetter glass fiber membrane filters are available in hydrophobic, hydrophilic, acid-treated with low metal content and copper acetate treatment version. The wide range of pore sizes  allow glass fiber membrane filters to be widely used in various industries.

As one of the leading enterprises in filtration and a technology driven company, Cobetter committed to providing customers in different industries with various solutions. Optimized manufacturing process and high quality standard allow us to provide most advanced membranes for each application.
