PPS Needle Felt Filter Cloth
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
PPS Needle Felt Filter Cloth is a type of high-performance non-woven filter media constructed from polyphenylene sulfide (PPS) fibers. These fibers are known for their excellent resistance to heat, chemical attack, and oxidation, making PPS filter cloth particularly suitable for harsh industrial environments. The term “needle felt” indicates that the fabric is made by mechanically interlocking the fibers through a needling process, which creates a porous yet dense material.
Here are the key characteristics of PPS Needle Felt Filter Cloth:
- High-Temperature Resistance: PPS filter cloth can withstand continuous exposure to temperatures typically up to 190°C, with a high melting point around 230°C.
- Chemical Resistance: It demonstrates strong resistance to acids, alkalis, and organic solvents, allowing for use in applications where corrosive gases are present.
- Hydrolysis Resistance: PPS fibers maintain their integrity in the presence of moisture and steam, providing stability in wet and humid conditions.
- Dimensional Stability: The material exhibits excellent dimensional stability, maintaining its shape and size under high temperatures and stress.
- Abrasion Resistance: The toughness of PPS fibers gives the filter cloth good resistance to abrasion, which is important for the longevity of filter bags in dust collection systems.
- Long Service Life: Due to its durable properties, PPS filter cloth tends to have a longer service life compared to other filtration materials, resulting in lower maintenance and replacement costs.
- Efficient Filtration Performance: The structure of the needle felt provides an effective area for capturing particulates while maintaining good air permeability.
PPS Needle Felt Filter Cloth is commonly utilized in filter bags for dust collection systems in industries such as coal-fired power plants, waste incineration, chemical processing, and metal smelting. Its ability to perform reliably in demanding conditions makes it a valuable component of industrial air pollution control equipment.

PPS (Polyphenylene Sulfide) Needle Felt Filter Cloth is a specialized filter media with a set of features that make it suitable for demanding filtration applications, particularly in industrial settings where high temperature and corrosive gases are present. The features of PPS Needle Felt Filter Cloth include:
- High-Temperature Resistance: PPS filter cloth can operate continuously at temperatures up to around 190°C (374°F), which makes it suitable for high-temperature filtration applications.
- Excellent Chemical Resistance: It has outstanding resistance to a wide range of chemicals, including acids, alkalis, and organic solvents, making it ideal for use in harsh chemical environments.
- Strong Hydrolysis Resistance: PPS fibers are resistant to hydrolysis, which is the chemical breakdown caused by reaction with water. This makes PPS filter cloth suitable for wet or humid conditions.
- Dimensional Stability: The material maintains its shape and dimensions under high temperatures and varying loads, ensuring consistent filtration performance.
- Good Abrasion Resistance: PPS filter cloth exhibits resistance to abrasion, which is beneficial in applications where the filter media might be subjected to mechanical wear.
- Low Thermal Conductivity: PPS fibers have low thermal conductivity, which contributes to energy savings in thermal processes by minimizing heat loss.
- Low Moisture Absorption: PPS fibers absorb very little moisture, which helps maintain filtration efficiency in humid conditions.
- Long Service Life: The combination of thermal and chemical stability, along with resistance to abrasion and hydrolysis, contributes to the long service life of PPS needle felt filter media.
- High Filtration Efficiency: The needle felting process creates a high surface area that enhances the capture of fine particles, leading to high filtration efficiency.
- Ease of Cleaning: The surface properties of PPS filter cloth facilitate the release of dust cakes during cleaning cycles, which is important for maintaining airflow and reducing energy consumption.
PPS Needle Felt Filter Cloth is widely used in dust collector systems for industries such as coal-fired power generation, incineration plants, cement production, metal processing, and chemical manufacturing.
