Polyester needle punched felt, which is made of polyester fibers(PET), can be
divided into PET staple fiber, PET filament and PET monofilament. These products
possess the properties of strong acid-resistance, fair alkali-resistance. The
operating temperature is 300°C.
They can be widely used in pharmaceuticals, non-ferrous metals metallurgical
and chemical industrials, in the equipments of frame filter presses, centrifuge
filters, vacuum filters, etc. The filtering precision can reach less than 5 microns.
