Acrylic Coated needle felt
 It is strong, abrasion resistant, can work up to 150°C and has good resistance to common acids, solvents and oxidising agents.

Disadvantages
Polyester's only real weakness is a tendency to hydrolyse at elevated temperature which means that moisture can break down the fibres and cause them to revert to their basic constituents. This results in powdering of the fibres and a serious loss of strength.

Application
Because of its favourable price/quality ratio, polyester is the most common fibre used in filter media.
