PPS Filter Bags
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, including:
- High Temperature Resistance – PPS filter bags can operate continuously at temperatures up to 160°C (320°F), with surges up to 190°C (375°F). This makes them ideal for applications where high temperatures are present, such as in incinerators, power generation, cement production, and metal processing.
- Excellent Chemical Resistance – PPS filter bags are resistant to a wide range of acids, alkalis, and solvents. This makes them suitable for applications where corrosive chemicals are present, such as in the chemical processing and pharmaceutical industries.
- Good Moisture Resistance – PPS filter bags are also resistant to moisture and hydrolysis. This makes them a good choice for applications where high humidity or wet conditions are present, such as in food processing and wastewater treatment.
- High Mechanical Strength – PPS filter bags have a high tensile strength and tear resistance, making them resistant to abrasion and tear. This is important in applications where the filter bags are subjected to high levels of wear and tear, such as in the mining and construction industries.
In addition to these filtration characteristics, PPS filter bags also offer a number of other advantages, such as:
- Long Service Life – PPS filter bags have a long service life, even in challenging operating conditions. This can lead to significant cost savings over time.
- Easy to Clean and Maintain – PPS filter bags are easy to clean and maintain, which helps to reduce downtime and improve productivity.
- Environmentally Friendly – PPS filter bags are made from a recyclable material, which makes them an environmentally friendly choice.
Scrim-supported felt is used exclusively in the production of Aokai PPS filter bags in order to improve filtration efficiency and to extend the filter bag life.
