Polyester Needle Felt By Zhejiang Heading Filter Material Co., Ltd.

Our range of Polyester Needle Felt is the most versatile, most cost effective and most widely used filter medium for dust collection. It is strong, abrasion resistant, can work up to 150A 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.
