Manufacturing Filter bags at Hongyuan Envirotech

The PTFE synthetic fiber filter bag is a product made from polytetrafluoroethylene, which is resistant to acid, alkali, and organic solvents. It can withstand high temperatures and has a low friction coefficient. This filter bag is suitable for use in harsh conditions where corrosion resistance is needed and has a long filter media life.

Our PTFE synthetic fiber filter bag is ideal for treating flue gas in coal-fired boilers, waste incineration, carbon black production, and titanium dioxide production. It is also used in the smelting, refining, and chemical production of certain metals. We offer this product in various specifications and it is highly regarded both domestically and internationally.

PTFE, also known as Teflon, is considered the top plastic due to its exceptional properties such as high temperature resistance (up to 280 degrees Celsius), long serves life, and non-stickiness. Because of these qualities, PTFE fiber is an ideal material for producing industrial filter cloths. Zonel Filtech specializes in offering PTFE filter cloths, specifically PTFE needle felt filter cloths.

Hongyuan uses only 100% top-quality PTFE (Teflon) fiber and PTFE filament scrim. These materials are then needle punched into felt and undergo special treatments such as singeing, glazing, heat setting, PTFE suspension bath, and PTFE membrane lamination. The resulting Teflon needle felt filter cloth (polytetrafluoretyhylene filter material) can be widely used in various industrial settings for dust collection (PTFE dust filter bags).


For more than 20 years, Hongyuan Envirotech Co., Ltd. has been a leading manufacturer of filter material and filter bags for dust filtration industry. Hongyuan Envirotech has been committed to providing customers best filter material with comprehensive cost performance.
