FMS compound Needle Punched Felt
FMS
is a good high temperature resistance filter fabrics, this fabrics
mainly made by 5.5 micron diameter glass fiber blend with P84
(polyimide), aramid(Nomex), PPS (ryton) fiber, with the three
dimensional cellular structure, low air resistance, especial blend with
P84 which with leaf style fiber, can increase the filter surface (80%),
so easy to collect the dust, increase the fiber cohesion, can accept the
high wind speed (50% higher about 1~1.4m/min), and also with the
properties of abrasion resistance. This kind of fabrics widely used in
metallurgical plant, chemical plant, coal fired boiler, incinerator,
cement plant for dust collector or smoke filtration in high temperature
circumstance.
