PPS+PTFE filter bags are made of polyphenylene sulfide (PPS) + polytetrafluoroethylene (PTFE). PPS+PTFE filter bags are renowned for their excellent filtration characteristics, including:
High temperature resistance - PPS+PTFE filter bags can operate continuously at temperatures up to 170°C (320°F) and can withstand surges up to 200°C (375°F). This makes them highly suitable for high-temperature applications such as incinerators, power generation, cement production, and metal processing.
Superior chemical resistance - PPS+PTFE filter bags can withstand various acids, alkalis, and solvents. This makes them suitable for applications involving corrosive chemicals, such as chemical processing and pharmaceutical industries.
Good moisture resistance - PPS+PTFE filter bags are also moisture-resistant and resistant to hydrolysis. This makes them a good choice for applications in high humidity or wet conditions, such as food processing and wastewater treatment.
High mechanical strength - PPS+PTFE filter bags have high tensile strength and tear resistance, making them wear-resistant. This is important in applications where filter bags are subjected to high levels of abrasion, such as mining and construction industries.
In addition to these filtration characteristics, PPS+PTFE filter bags also have many other advantages, such as:
Long service life - PPS+PTFE filter bags have a long service life, even under challenging operating conditions. Over time, this can significantly save costs.
Easy to clean and maintain - PPS+PTFE filter bags are easy to clean and maintain, helping to reduce downtime and improve productivity.

Q7.How to choose material for filter bag with good price ?
Since every filter has its own characteristics and parameters, when we choose filter material for dust collector filter bag, we have to know the following parameters:
(1) Working temperature
(2) Humidity
(3) Dust diameter
(4) Gas' chemical properties
(5) Dust abrasiveness
(6) Filter's mechanical parameters
Q8.When we produce the filter bags ,you need to provide the below size :
(1)The diameter of the filter bags /the semi-perimeter of the filter bags
(2)The length of the filter bags
(3)The diameter of CPO and the thickness of CPO on dust collector on dust collector
(4)The drawing of the filter bags or the sample of the bag
(5)The material of the filter bags
(6)The type of the filter bags : round or flat ,the type of the filter bag top : snap cuff or snap ring
(7)The application of the filter bags ,cement ,asphalt ,power plant , chemical ,waste incineration , metallurgy and so on.
