Product Description:

PTFE Fiber Alkali Resistance Filter Bags for Industrial Use

PTFE filter bags are very suitable for dust removal in various industries, such as chemical, pharmaceutical, food processing, etc. With high temperature resistance, PTFE coating process and chemical resistance, PTFE filter bags are also very suitable for applications requiring fire-resistant flame-retardant and anti-static properties.


PTFE filter bag is a filter bag made of a unique material. Under the conditions of continuous operating temperature of 240°C and instantaneous temperature of 260°C, it can resist acid and alkali corrosion in the entire pH range. PTFE filter bags are self-wetting, moisture-resistant, and resistant to ultraviolet radiation.

PTFE Filter Bags

The wear resistance of PTFE filter bags is average, so the frame of PTFE filter bags requires strict grid requirements (smoothness). PTFE filter bags are more suitable for harsh conditions that require filter materials to be corrosion resistant and have a long service life.


1. The dust itself is relatively viscous. When the PTFE filter bag is in contact with the filter material fibers, the intermolecular force is relatively strong. For example, oily particles, ammonium sulfate sulfuric acid produced by denitrification, nitric lime for desulfurization, etc.

2. Although some dust will not stick in the PTFE filter bag, it is easy to deliquescence. When it becomes trapped on the fiber surface, it absorbs moisture from the air and forms a solution such as powdered sugar on the fiber surface.

3. PTFE filter bags may not have strong dust adhesion, but they can absorb moisture in the flue gas and undergo a chemical recrystallization process to produce new hydraulic substances or crystals, forming a "shell" that covers the filter material surface. Such as cement clinker and desulfurization products - calcium sulfate.
