Polyester (PES)

Polyester – the most versatile, cost-effective and most common filter cloth for dust collection. It is durable, abrasion resistant, can operate at temperatures up to 150° C and has good resistance to most acids, solvents and oxidants.

 Its one weakness is a tendency to hydrolyze which results in a loss of strength and toughness as the fibers break down and turn to powder.

A wide variety of chemical and thermal treatments are available for polyester, the most common being superglaze to improve dust release and liquid repellency to assist with sticky.

Applicable in the relevant sectors of:

  • Cement industry
  • Plaster industry
  • Ceramic industry
  • Plastic industry
  • Grain industry
  • Mining industry
  • Steel industry
  • Metal industry
Chemical resistance:

  • Acids – not bad
  • Alkalis – not bad
  • Oxidizing – not bad
  • Hydrolysis – bad
  • Solvents – good
