PET Conductive Fiber Needle Punch Nonwoven Fabric
550g PET And Conductive Fiber Blending Needled Felt Anti-Static Punch Felt Membrane PET Needled Filter Fabric
Description
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 150°C and has good resistance to common acids, solvents and oxidising agents.
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.
