Chemical resistance of bag filter media
  • Fibres used as media for bag filters such as polyester, polypropylene, nylon and nomex holds different characteristics depending on its chemical state and temperature.
WOUND FILTER
Polyester As the most used fibre, it has good economical efficiency, chemical resistance and heat resistance between 150-170℃.
Polypropylene Widely used in all fields of Chemical Industry due to its good resistance to acidity and basicity. However, it is only applicable within the temperature range of 90-100℃ and it is not suitable for Aromatic Hydrocarbon.
Nylon Chemical Resistance (except for Acidic Media) and high heat resistance (150-170℃)
