1. Fiberglass needle felt is a new style high temperature filter cloth of rational composition and excellent property.
made of 100% fiberglass by needling. It not only possesses the advantages of high temperature, corrosion resistan
-ce, fit stability, powerful strength, but also has high filter efficiency , up to 99%, because of its three-dimensional
structure and high porosity. Its filtering speed is once higher than woven filtering cloth. This product is applied in carbon black chemistry, ferrousmetallurgy, coal-fire boiler, fire resistance material and cement etc. to govern dust
pollution and recycle valuable micro grain.
