PPS Filter Bag
PPS (Polyphenylene Sulfide) Needle Felt Filter Cloth, also known by the brand name Ryton, is a type of high-performance non-woven filter media used for dust collection and air filtration in industrial applications.
Product Details
A PPS filter bag is a type of industrial filter bag made from Polyphenylene Sulfide (PPS) fibers. PPS is a high-performance thermoplastic polymer known for its exceptional resistance to heat and chemicals, making it suitable for harsh environments. The acronym “PPS” can also refer to the commercial name Ryton®, which is a brand of PPS fibers.
The key features and benefits of PPS filter bags include:
- Heat Resistance: PPS filter bags can withstand continuous high temperatures, typically up to 190°C (375°F), without degrading.
- Chemical Resistance: These filter bags offer excellent resistance to both acids and alkalis, as well as organic solvents, enabling their use in a variety of harsh chemical environments.
- Hydrolysis Resistance: PPS fibers are resistant to hydrolysis, ensuring stable performance in moist or wet conditions.
- Durability: The intrinsic strength of PPS fibers provides a long service life for the filter bags, contributing to lower maintenance costs and fewer replacements.
- Efficient Filtration: PPS filter bags are effective at capturing fine particulate matter, helping to maintain clean air emissions and comply with environmental regulations.
- Low Emission Levels: The material’s tight pore structure helps achieve low particulate emissions from the dust collection system.
- Customizable: These filter bags can be produced in various sizes and shapes to fit different dust collector systems and can include special treatments or finishes according to the application needs.
- Applications: PPS filter bags are typically used in applications such as coal-fired power plants, waste incinerators, kilns, and chemical processing facilities where the filtration of hot and corrosive gases is required.
PPS filter bags are a critical component in air pollution control systems where thermal stability and chemical resistance are paramount for efficient and reliable operation. They are designed to filter out particulates from industrial exhaust streams while withstanding the rigors of continuous operation in challenging conditions.
