Polyester Needle Punched Filter Felt By Shandong Aobo Environmental Protection Technology Co.,ltd.

Starting to be one of the apparent companies in the organization, we are Exporting a big series of Polyester Needle Punched Filter Felt in Dezhou, Shandong, China that 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 favorable price/quality ratio, polyester is the most common fibre used in filter media.
