Fumex( FMS) heat-resisting needle-punched filter material :
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:
