Description

Polyester Needle Felt Media
 
Overview:
Polyester Needle Felt Media is made from polyester fiber. The material has better anti-abrasion and higher porosity, good twist resistance. It is a kind of widely applied normal temperature filter material. We suggest the normal application must be ****0℃ above the dew point temperature.

Polyester Needle Felt Media 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 **0°C and has good resistance to common acids, solvents and oxidizing agents.
Disadvantages 
Polyester's only real weakness is a tendency to hydrolyze at elevated temperature which means that moisture can break down the fibers and cause them to revert to their basic constituents. This results in powdering of the fibers and a serious loss of strength.
 
Application
Because of its favorable price/quality ratio, polyester is the most common fiber used in filter media.
