Fumex(
FMS) heat-resisting needle-punched filter material
Back
|
|
FMS heat-resisting needle-punched felt is a new
type heating resistant product. It was developed in 1997 and
manufactured in 1998. It is made of more than two varieties of heat-resisting fiber
for getting better chemical performance,. The trade name has been
fixed as FMS, and has applied trade mark registration.
|
|
FMS needle-punched felt has many advantages such
as heat-resisting, high strength and resistance to corrosion. After
chemical treatment and finishing , It
also possess the abilities of easily cleaning, waterproof,
antistatic and so on. And also different temperatures (e.g. 150-200℃、200-250℃、250-300℃),
we have different products to meet them.
|
|
FMS is more hard-wearing and more strong than
fiber glass, so it can work quickly and can load more pressure.
Compared with synthetic chemical fiber, FMS is heat-resisting and
corrosion resisting with good stability, strength and low cost.
|
|
FMS,
developed to meet our situation of country, is widely used in steel,
color metallurgy, chemical industry, construction, electric powder
etc. Performance as follow table:
