Excellent high temperature resistance: For extended periods of time, Polytetrafluoroethylene (PTFE) Filter Felt can withstand temperatures as high as 220°C without melting or degrading.  Because PTFE has a very low coefficient of friction, contaminants are less likely to stick to its surface, making it easier to clean.
Chemical resistance : PTFE has excellent chemical resistance and can resist the erosion of a variety of corrosive substances such as strong acids, strong alkalis, and solvents.
Wear resistance: PTFE Filter Felt resists wear and breaks less readily than other Filter Felt because of its high wear resistance.
Lasting: Because of their resistance to chemicals and temperatures, PTFE filter felts usually have a long lifespan.
High Filtration Efficiency: PTFE filter felts are able to effectively capture fine particles and particulates because of the fine nature of PTFE fibers.
