Commonly known as Teflon® filter bags, which are made from PTFE, short for polytetrafluoroethylene. PTFE is a high-performance synthetic polymer with unique properties. In addition to being hydrophobic, which means it repels water, PTFE is known for its chemical resistance, non-stickiness, high-temperature tolerance, and low friction coefficient. These properties make PTFE filter bags ideal for a wide range of filtration applications.

PPS filter bags are made from polyphenylene sulfide (PPS), which is a high-performance thermoplastic polymer, also otherwise known by the proprietary name Ryton© or Procon©. Polyphenylene sulfide filter bags are known for their excellent filtration characteristics.

Aramid filter bags are made of a synthetic fiber material called aramid, also known as Nomex. It was first developed in the 1960s and made commercially available in 1967 by DuPont. For filtration applications, it is most often known as Meta Aramid.

Fiberglass filter bags are widely used in industrial dust collection and filtration applications. They are made of fine glass fibers that are woven or nonwoven into a fabric.
